Jasuja R, Pencina KM, Spencer DJ, et al., 2023, Reference intervals for free testosterone in adult men measured using a standardized equilibrium dialysis procedure., Andrology, Vol: 11, Pages: 125-133
BACKGROUND: Free testosterone (FT) determination may be helpful in evaluating men suspected of testosterone deficiency especially in conditions with altered binding-protein concentrations. However, methods for measuring FT by equilibrium dialysis and reference intervals vary among laboratories. OBJECTIVE: To determine reference intervals for FT in healthy, nonobese men by age groups as well as in healthy young men, 19-39 years, using a standardized equilibrium dialysis procedure METHODS: We measured FT in 145 healthy, nonobese men, 19 years or older, using a standardized equilibrium dialysis method performed for 16-h at 37°C using undiluted serum and dialysis buffer that mimicked the ionic composition of human plasma. FT in dialysate was measured using a CDC-certified liquid chromatography tandem mass spectrometry assay. RESULTS: In healthy nonobese men, the 2.5th, 10th, 50th, 90th, and 97.5th percentile values for FT were 66, 91, 141, 240, and 309 pg/ml, respectively; corresponding values for men, 19-39 years, were 120, 128, 190, 274, and 368 pg/ml, respectively. FT levels by age groups exhibit the expected age-related decline. FT levels were negatively associated with body mass index, age, and sex hormone-binding globulin (SHBG) levels. Percent FT was lower in middle-aged and older men than young men adjusting for SHBG level. DISCUSSION: Further studies are needed to determine how these reference intervals apply to the diagnosis of androgen deficiency in clinical populations and in men of different races and ethnicities in different geographic regions. CONCLUSION: Reference intervals for free FT levels (normative range 66-309 pg/ml [229-1072 pmol/L] in all men and 120-368 pg/ml [415-1274 pmol/L] in men, 19-39 years), measured using a standardized equilibrium dialysis method in healthy nonobese men, provide a rational basis for categorizing FT levels. These intervals require further validation in other populations, in relation to outcomes, and in randomized tri

Electrochemical aptamer-based (E-AB) sensors using conformational change-induced electron transfer kinetics are sensitive, reagent-less, and cost-effective tools for molecular sensing. Current advances in this technology can allow continuous drug pharmacokinetic monitoring in living animals (Dauphin-Ducharme et al., ACS Sens 4(10):2832-2837, 2019; Idili et al., Chem Sci 10(35):8164-8170, 2019), as well as automated analysis of hormone pulsatility (Liang et al., Nat Commun 10(1):852, 2019). In this chapter, we provide the methodology for an automated E-AB conformational change-based robotic sensing platform. By using an open-source programmable robotic system, this method can be adapted to a wide range of experimental scenarios.

Kisspeptin is a hypothalamic neuropeptide that acts via the hypothalamus to stimulate hypothalamic gonadotrophin-releasing hormone secretion and downstream gonadotrophin release. In health, kisspeptin induces normal puberty and modulates ovulation in healthy women. Hypothalamic kisspeptin expression is reduced in several functional reproductive disorders; thus, treating such conditions with kisspeptin is conceptually attractive. Recent studies have demonstrated that kisspeptin can induce a more physiological degree of oocyte maturation during in vitro fertilisation treatment that can reduce the risk of potentially life-threatening complications such as ovarian hyperstimulation syndrome seen with human chorionic gonadotrophin. Furthermore, chronic use of kisspeptin could potentially restore reproductive health in females with hypothalamic amenorrhoea, treat hyposexual drive disorder in otherwise healthy males and has potential indications in polycystic ovary syndrome, osteoporosis and metabolic dysfunction-associated fatty liver disease. Finally, kisspeptin analogues could potentially overcome some of the pharmacological challenges associated with the natural forms of kisspeptin such as short duration of action and development of tachyphylaxis.

Thurston L, Hunjan T, Ertl N, et al., 2022, Effects of kisspeptin administration in women with hypoactive sexual desire disorder: a randomized clinical trial, Jama Network Open, Vol: 5, Pages: 1-14, ISSN: 2574-3805
Importance: The absence or deficiency of sexual desire leading to distress or interpersonal difficultydefines ‘hypoactive sexual desire disorder’ (HSDD). Despite being the most common female sexualhealth complaint worldwide, current treatment options for HSDD are limited in their safety andeffectiveness. The hormone kisspeptin is a key endogenous activator of the reproductive hormonalaxis with additional emerging roles in sexual and emotional behavior, however, its effects in womenwith HSDD are unknown.Objective: To test the hypothesis that kisspeptin enhances sexual and attraction brain processing inwomen with HSDD.Design: A randomized, double-blind, two-way crossover, placebo-controlled clinical trial. Functionalneuroimaging, psychometric and hormonal analyses were employed to investigate the effects ofkisspeptin administration on brain processing, in response to erotic stimuli (erotic videos) and facialattraction (face images of varying attractiveness).Setting: The trial was conducted in a university research setting from October 2020 to April 2021. Datawere analyzed from May to December 2021.Participants: 32 premenopausal women with HSDD for at least 6 months’ duration.Interventions: 75-minute intravenous infusion of kisspeptin-54 (1 nmol/kg/h) vs equivalent-rateplacebo infusion.Main Outcome and Measures: Blood oxygen level–dependent responses across the whole brain andregions of interest during kisspeptin vs placebo administration, in response to erotic and facialattraction stimuli.Results: Of the 40 participants who were randomized, 32 women completed both kisspeptin andplacebo visits, and the mean (SEM) age was 29.2 (1.2) years. Kisspeptin administration resulted inmodulations in sexual and facial attraction brain processing (all P<.05). Furthermore, positivecorrelations were observed between kisspeptin-enhanced hippocampal activity in response to eroticvideos, and baseline distress relating to sexual function (P<.01). In additio

Thurston L, Hunjan T, Mills E, et al., 2022, Melanocortin 4 receptor agonism enhances sexual brain processing in women with hypoactive sexual desire disorder, Journal of Clinical Investigation, Vol: 132, Pages: 1-12, ISSN: 0021-9738
BACKGROUND. Hypoactive sexual desire disorder (HSDD) is characterized by a persistent deficiency of sexual fantasies and desire for sexual activity, causing marked distress and interpersonal difficulty. It is the most prevalent female sexual health problem globally, affecting approximately 10% of women, but has limited treatment options. Melanocortin 4 receptor (MC4R) agonists have emerged as a promising therapy for women with HSDD, through unknown mechanisms. Studying the pathways involved is crucial for our understanding of normal and abnormal sexual behavior.METHODS. Using psychometric, functional neuroimaging, and hormonal analyses, we conducted a randomized, double-blinded, placebo-controlled, crossover clinical study to assess the effects of MC4R agonism compared with placebo on sexual brain processing in 31 premenopausal heterosexual women with HSDD.RESULTS. MC4R agonism significantly increased sexual desire for up to 24 hours after administration compared with placebo. During functional neuroimaging, MC4R agonism enhanced cerebellar and supplementary motor area activity and deactivated the secondary somatosensory cortex, specifically in response to visual erotic stimuli, compared with placebo. In addition, MC4R agonism enhanced functional connectivity between the amygdala and the insula during visual erotic stimuli compared with placebo.CONCLUSION. These data suggest that MC4R agonism enhanced sexual brain processing by reducing self-consciousness, increasing sexual imagery, and sensitizing women with HSDD to erotic stimuli. These findings provide mechanistic insight into the action of MC4R agonism in sexual behavior and are relevant to the ongoing development of HSDD therapies and MC4R agonist development more widely.TRIAL REGISTRATION.

Sharma B, Koysombat K, Dhillo W, et al., 2022, Use of kisspeptin to trigger oocyte maturation during in vitro fertilisation (IVF) treatment, Frontiers in Endocrinology, Vol: 13, Pages: 1-9, ISSN: 1664-2392
Infertility is a major global health issue and is associated with significant psychological distress for afflicted couples. In vitrofertilisation (IVF) utilises supra-physiological doses of stimulatory hormones to induce the growth of multiple ovarian follicles toenable surgical retrieval of several oocytes for subsequent fertilisation and implantation into the maternal endometrium. Thesupra-physiological degree of ovarian stimulation can lead to potential risks during IVF treatment, including ovarianhyperstimulation syndrome (OHSS) and multiple pregnancy.The choice of oocyte maturation trigger, such as human chorionic gonadotrophin (hCG) or gonadotrophin releasing hormoneagonist (GnRHa), can impact both the efficacy of IVF treatment with a bearing on luteal phase hormonal dynamics and thus thedegree of luteal phase support required to maintain optimal pregnancy rates, as well as on safety of treatment with particularrespect to the risk of OHSS. Kisspeptin regulates gonadotrophin releasing hormone (GnRH) release and is therefore a key regulatorof the hypothalamo-pituitary-gonadal (HPG) axis. Kisspeptin has been shown to be requisite for the occurrence of the physiologicalovulatory luteinising hormone (LH) surge. In this review, we discuss the potential use of kisspeptin as a novel trigger of oocytematuration.

Tsoutsouki J, Patel B, Dhillo W, et al., 2022, Kisspeptin in the prediction of pregnancy complications, Frontiers in Endocrinology, Vol: 13, ISSN: 1664-2392
Kisspeptin and its receptor are central to reproductive health acting as key regulators of the reproductive endocrine axis in humans. Kisspeptin is most widely recognised as a regulator of gonadotrophin releasing hormone (GnRH) neuronal function. However, recent evidence has demonstrated that kisspeptin and its receptor also play a fundamental role during pregnancy in the regulation of placentation. Kisspeptin is abundantly expressed in syncytiotrophoblasts, and its receptor in both cyto- and syncytio-trophoblasts. Circulating levels of kisspeptin rise dramatically during healthy pregnancy, which have been proposed as having potential as a biomarker of placental function. Indeed, alterations in kisspeptin levels are associated with an increased risk of adverse maternal and foetal complications. This review summarises data evaluating kisspeptin’s role as a putative biomarker of pregnancy complications including miscarriage, ectopic pregnancy (EP), preterm birth (PTB), foetal growth restriction (FGR), hypertensive disorders of pregnancy (HDP), pre-eclampsia (PE), gestational diabetes mellitus (GDM), and gestational trophoblastic disease (GTD).
Mills E, Yang L, Abbara A, et al., 2022, Current perspectives on kisspeptins role in behaviour, Frontiers in Endocrinology, Vol: 13, ISSN: 1664-2392
The neuropeptide kisspeptin is now well-established as the master regulator of the mammalian reproductive axis. Beyond the hypothalamus, kisspeptin and its cognate receptor are also extensively distributed in extra-hypothalamic brain regions. An expanding pool of animal and human data demonstrates that kisspeptin sits within an extensive neuroanatomical and functional framework through which it can integrate a range of internal and external cues with appropriate neuroendocrine and behavioural responses. In keeping with this, recent studies reveal wide-reaching effects of kisspeptin on key behaviours such as olfactory-mediated partner preference, sexual motivation, copulatory behaviour, bonding, mood, and emotions. In this review, we provide a comprehensive update on the current animal and human literature highlighting the far-reaching behaviour and mood-altering roles of kisspeptin. A comprehensive understanding of this important area in kisspeptin biology is key to the escalating development of kisspeptin-based therapies for common reproductive and related psychological and psychosexual disorders.
Hudson J, Cruickshank M, Quinton R, et al., 2022, Adverse cardiovascular events and mortality in men during testosterone treatment: an individual patient and aggregate data meta-analysis., The Lancet Healthy Longevity, Vol: 3, Pages: e381-e393, ISSN: 2666-7568
Background: Testosterone is the standard treatment for male hypogonadism, but there is uncertainty about its cardiovascular safety due to inconsistent findings. We aimed to provide the most extensive individual participant dataset (IPD) of testosterone trials available, to analyse subtypes of all cardiovascular events observed during treatment, and to investigate the effect of incorporating data from trials that did not provide IPD. Methods: We did a systematic review and meta-analysis of randomised controlled trials including IPD. We searched MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, MEDLINE Epub Ahead of Print, Embase, Science Citation Index, the Cochrane Controlled Trials Register, Cochrane Database of Systematic Reviews, and Database of Abstracts of Review of Effects for literature from 1992 onwards (date of search, Aug 27, 2018). The following inclusion criteria were applied: (1) men aged 18 years and older with a screening testosterone concentration of 12 nmol/L (350 ng/dL) or less; (2) the intervention of interest was treatment with any testosterone formulation, dose frequency, and route of administration, for a minimum duration of 3 months; (3) a comparator of placebo treatment; and (4) studies assessing the pre-specified primary or secondary outcomes of interest. Details of study design, interventions, participants, and outcome measures were extracted from published articles and anonymised IPD was requested from investigators of all identified trials. Primary outcomes were mortality, cardiovascular, and cerebrovascular events at any time during follow-up. The risk of bias was assessed using the Cochrane Risk of Bias tool. We did a one-stage meta-analysis using IPD, and a two-stage meta-analysis integrating IPD with data from studies not providing IPD. The study is registered with PROSPERO, CRD42018111005. Findings: 9871 citations were identified through database searches and after exclusion of duplicates and of irrelevant citations, 225
Guzman S, Dragan M, Kwon H, et al., 2022, Targeting hepatic kisspeptin receptor ameliorates non-alcoholic fatty liver disease in a mouse model., Journal of Clinical Investigation, Vol: 132, Pages: 1-20, ISSN: 0021-9738
Nonalcoholic fatty liver disease (NAFLD), the most common liver disease has become a silent worldwide pandemic. The incidence of NAFLD correlates with the rise in obesity, type 2 diabetes and metabolic syndrome. A hallmark feature of NAFLD is excessive hepatic fat accumulation or steatosis, due to dysregulated hepatic fat metabolism which can progress to nonalcoholic steatohepatitis (NASH), fibrosis and cirrhosis. Currently, there are no approved pharmacotherapies to treat this disease. Here we have identified that activation of the kisspeptin receptor (KISS1R) signaling pathway has therapeutic effects in NAFLD. Using high fat diet-fed mice, we demonstrated that a deletion of hepatic Kiss1r exacerbated hepatic steatosis. In contrast, enhanced stimulation of KISS1R protected against steatosis in wild-type C57BL/6J mice and decreased fibrosis using a diet-induced mouse model of NASH. Mechanistically, we found that hepatic KISS1R signaling activates the master energy regulator, AMPK, to thereby decrease lipogenesis and progression to NASH. In NAFLD patients and in HFD-fed mice, hepatic KISS1/KISS1R expression and plasma kisspeptin levels were elevated, suggesting a compensatory mechanism to reduce triglyceride synthesis. These findings establish KISS1R as a therapeutic target to treat NASH.

Patel B, S Dhillo W, 2022, Menopause review: Emerging treatments for menopausal symptoms., Best Pract Res Clin Obstet Gynaecol, Vol: 81, Pages: 134-144
Vasomotor symptoms (VMS) affect 2 out of 3 women during menopause and are highly disruptive and intolerable. They exert a negative impact on a woman's physical and mental well-being and are considered a high clinical priority requiring effective treatment. Although hormone therapy remains the gold-standard treatment for hot flushes, it is associated with several side effects and contraindications. Furthermore, alternative treatments for VMS are currently less efficacious and have limited availability; therefore, a new medication to treat VMS would benefit millions of women worldwide. Neurokinin 3 receptor (NK3R) antagonists have recently been developed as novel therapeutic agents for the amelioration of VMS through their action on NK3 receptors within the hypothalamus and consequent regulation of the thermoregulatory centre. So far, three NK3R antagonists have been studied in menopausal women, which have demonstrated significant reductions in VMS frequency and severity and have shown their ability to transform patients' quality of life.

Comninos AN, Hansen MS, Courtney A, et al., 2022, Acute effects of kisspeptin administration on bone metabolism in healthy men, Journal of Clinical Endocrinology and Metabolism, Vol: 107, ISSN: 0021-972X
CONTEXT: Osteoporosis results from disturbances in bone formation and resorption. Recent non-human data suggests that the reproductive hormone, kisspeptin, directly stimulates osteoblast differentiation in vitro and thus could have clinical therapeutic potential. However, the effects of kisspeptin on human bone metabolism are currently unknown. OBJECTIVE: To assess the effects of kisspeptin on human bone metabolism in vitro and in vivo. DESIGN: In vitro study: Mono- and co-cultures of human osteoblasts and osteoclasts treated with kisspeptin. Clinical study: Randomized, placebo-controlled, double-blind, two-way crossover clinical study in twenty-six men investigating the effects of acute kisspeptin administration (90 minutes) on human bone metabolism, with blood sampling every 30 minutes to +90 minutes. PARTICIPANTS: In vitro study: Twelve male blood donors and eight patients undergoing hip replacement surgery. Clinical Study: Twenty-six healthy eugonadal men (age 26.8±5.8 years). INTERVENTION: Kisspeptin (versus placebo). MAIN OUTCOME MEASURES: Changes in bone parameters and turnover markers. RESULTS: Incubation with kisspeptin in vitro increased alkaline phosphatase levels in human bone marrow mesenchymal stem cells by 41.1% (P=0.0022), and robustly inhibited osteoclastic resorptive activity by up to 53.4% (P<0.0001), in a dose-dependent manner. Kisspeptin administration to healthy men increased osteoblast activity, as evidenced by a 20.3% maximal increase in total osteocalcin (P=0.021) and 24.3% maximal increase in carboxylated osteocalcin levels (P=0.014). CONCLUSIONS: Collectively, these data provide the first human evidence that kisspeptin promotes osteogenic differentiation of osteoblast progenitors and inhibits bone resorption in vitro. Furthermore, kisspeptin acutely increases the bone formation marker osteocalcin but not resorption markers in healthy men, independent of downstream sex-steroid levels. Kisspeptin could therefore have clinical thera

Aceves-Martins M, Quinton R, Brazzelli M, et al., 2022, Identifying the outcomes important to men with hypogonadism: A qualitative evidence synthesis, Andrology, Vol: 10, ISSN: 2047-2919
OBJECTIVE: Men with male hypogonadism (MH) experience sexual dysfunction, which improves with testosterone replacement therapy (TRT). However, randomised controlled trials provide little consensus on functional and behavioural symptoms in hypogonadal men; these are often better captured by qualitative information from individual patient experience. METHODS: We systematically searched major electronic databases to identify qualitative data from men with hypogonadism, with or without TRT. Two independent authors performed the selection, extraction, and thematic analysis of data. Quality of eligible studies was assessed using the Critical Appraisals Skills Programme and Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research tools. RESULTS: We analysed data from five studies published in nine reports that assessed a total of 284 participants. Published data were only available within North America, with no ethnic minority or other underserved groups included. In addition to sexual dysfunction, men with MH experienced adverse changes in physical strength, perceptions of masculinity, cognitive function, and quality of life. The experience of MH appeared dependent on the source(s) of educational material. DISCUSSION: We propose a patient-centred approach to clinician interactions rather than focusing on discreet MH symptoms. Current evidence about the experience of MH is limited to North America and predominantly white ethnicity, which may not be broadly applicable to other geographic regions. Broadening our understanding of the MH experience may improve the targeting of information to patients. In addition, a multidisciplinary approach may better address symptoms neither attributable to MH nor alleviated by TRT.

Phylactou M, Abbara A, Al-Memar M, et al., 2022, Changes in circulating kisspeptin levels during each trimester in women with antenatal complications, Journal of Clinical Endocrinology and Metabolism, Vol: 107, Pages: e71-e83, ISSN: 0021-972X
ContextAntenatal complications such as hypertensive disorders of pregnancy (HDP), fetal growth restriction (FGR), gestational diabetes (GDM), and preterm birth (PTB) are associated with placental dysfunction. Kisspeptin has emerged as a putative marker of placental function, but limited data exist describing circulating kisspeptin levels across all three trimesters in women with antenatal complications.ObjectiveTo assess whether kisspeptin levels are altered in women with antenatal complications.DesignWomen with antenatal complications (n=105) and those with uncomplicated pregnancies (n=265) underwent serial ultrasound scans and blood-sampling at least once during each trimester (March 2014 to March 2017).SettingEarly Pregnancy Assessment Unit at Hammersmith Hospital, UK.ParticipantsWomen with antenatal complications: HDP (n=32), FGR (n=17), GDM (n=35) and PTB (n=11), and 10 women with multiple complications, provided 373 blood samples, and a further 265 controls provided 930 samples.Main outcomeDifferences in circulating kisspeptin levels.ResultsThird trimester kisspeptin levels were higher than controls in HDP but lower in FGR. The odds of HDP adjusted for gestational age, maternal age, ethnicity, BMI, smoking and parity were increased by 30% (95%CI 16-47%; p<0.0001), and of FGR were reduced by 28% (95%CI 4-46%; p=0.025), for every 1 nmol/L increase in plasma kisspeptin. Multiple of gestation-specific median values of kisspeptin were higher in pregnancies affected by PTB (p=0.014), and lower in those affected by GDM (p=0.020), but not significantly on multivariable analysis.ConclusionWe delineate changes in circulating kisspeptin levels at different trimesters and evaluate the potential of kisspeptin as a biomarker for antenatal complications.
