    GONADOPENIA AND AGING IN MEN.
    Endocr Pract 2018 Apr;24(4):375-385
    Objective: The decrease in testosterone levels that occurs with aging has become an important clinical issue both due to the growth of the geriatric population and patient interest in testosterone therapy. The decision to assess for testosterone deficiency and the ability to determine whether the benefits exceed the risks require a comprehensive evaluation of the aging patient. This article is part of a series of papers focused on the endocrinology of aging. Read More

    Constitutively active follicle-stimulating hormone receptor enables androgen-independent spermatogenesis.
    J Clin Invest 2018 Mar 26. Epub 2018 Mar 26.
    Institute of Reproductive and Developmental Biology (IRDB), Department of Surgery and Cancer, Imperial College London, Hammersmith Hospital Campus, London, United Kingdom.
    Spermatogenesis is regulated by the 2 pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This process is considered impossible without the absolute requirement of LH-stimulated testicular testosterone (T) production. The role of FSH remains unclear because men and mice with inactivating FSH receptor (FSHR) mutations are fertile. Read More

    Recombinant luteinizing hormone supplementation to recombinant follicle stimulating hormone therapy in gonadotropin releasing hormone analogue cycles: what is the evidence?
    Curr Med Res Opin 2018 May 15;34(5):881-886. Epub 2018 Jan 15.
    c Reproductive Medicine, Department of Obstetrics and Gynecology , Hadassah-Hebrew University Medical Center , Ein-Kerem , Jerusalem , Israel.
    Objective: To look into current evidence exploring the added value of rLH supplementation to rFSH in GnRH analogues cycles, to identify groups of women that still have no evidence for adjuvant rLH therapy and to discuss ways that may advance research on this topic.

    Methods: Eight systematic reviews and meta-analyses exploring the benefit for pregnancy achievement of rLH supplementation, excluding other LH activity preparations, to GnRH analogues cycles in the ART setting were thoroughly evaluated.

    Results: Evidence exists to show that rLH supplementation seems to have added value for pregnancy achievement in women with poor ovarian response and in women ≥35 years of age employing the GnRH agonist protocol, while the evidence is still debatable when the GnRH antagonist is administered.

    Reproductive Endocrinology Department, Le Kremlin-Bicêtre, F-94275, France.
    Context: Hyperprolactinemia-induced hypogonadotropic amenorrhea (hPRL-HA) is a major cause of hypothalamic gonadotrophin-releasing hormone (GnRH) deficiency in women. In hyperprolactinemic mice, we previously demonstrated that hypothalamic kisspeptin (Kp) expression was diminished and that Kp administration restored hypothalamic GnRH release, gonadotropin secretion, and ovarian cyclicity, suggesting that Kp neurons could also play a role in hPRL-HA.

    The presence of symptoms of testosterone deficiency in the exercise-hypogonadal male condition and the role of nutrition.
    Eur J Appl Physiol 2017 Jul 3;117(7):1349-1357. Epub 2017 May 3.
    Department of Human Sciences, The Ohio State University, A054 PAES Building, 305 Annie and John Glenn Avenue, Columbus, OH, 43210, USA.
    Purpose: High volumes of aerobic exercise have been associated with reduced testosterone (T), known as the exercise-hypogonadal male condition (EHMC). Although the presence of low T has been identified, few studies have assessed the presence of androgen-deficient symptoms. The purpose of this investigation is to assess men exhibiting EHMC and evaluate their hypothalamic-pituitary-gonadal axis, the presence of hypogonadal symptoms, and also investigate a possible contribution of inadequate nutrition to the condition.

    Pulsatile GnRH Therapy May Restore Hypothalamus-Pituitary-Testis Axis Function in Patients With Congenital Combined Pituitary Hormone Deficiency: A Prospective, Self-Controlled Trial.
    J Clin Endocrinol Metab 2017 Jul;102(7):2291-2300
    Department of Endocrinology, Peking Union Medical College Hospital, Key Laboratory of Endocrinology, Ministry of Health, Beijing 100730, China.
    Context: The effectiveness of pulsatile gonadotropin-releasing hormone (GnRH) therapy in patients with congenital combined pituitary hormone deficiency (CCPHD) has not been investigated because of the limited number of patients, as well as these patients' presumed pituitary hypoplasia, poor gonadotrophic cell reserve, and impaired gonadotrophic response to GnRH.

    Objective: To assess the pituitary response to pulsatile GnRH therapy in men with CCPHD.

    Design: Prospective, self-controlled, 3-month clinical trial. Read More

    Long-Term Neonatal Estrogen Exposure Causes Irreversible Inhibition of LH Pulses by Suppressing Arcuate Kisspeptin Expression via Estrogen Receptors α and β in Female Rodents.
    Endocrinology 2017 09;158(9):2918-2929
    Graduate School of Bioagricultural Sciences, Nagoya University, Nagoya, Aichi 464-8601, Japan.
    Exposure to estrogen during the developmental period causes reproductive dysfunction in mammals, because the developing brain is highly sensitive to estrogens. In the present study, we report that long-term exposure to supraphysiological doses of estrogen during the neonatal critical period causes irreversible suppression of Kiss1/kisspeptin expression in the arcuate nucleus (ARC) via estrogen receptor-alpha (ERα) and ERβ, resulting in reproductive dysfunction in female rats. Daily estradiol-benzoate (EB) administration from days 0 to 10 postpartum caused persistent vaginal diestrus in female rats. Read More

    Anti-Müllerian Hormone and Ovarian Morphology in Women With Isolated Hypogonadotropic Hypogonadism/Kallmann Syndrome: Effects of Recombinant Human FSH.
    J Clin Endocrinol Metab 2017 Apr;102(4):1102-1111
    Assistance Publique-Hôpitaux de Paris.
    Context: Isolated hypogonadotropic hypogonadism (IHH), characterized by gonadotropin deficiency and absent puberty, is very rare in women. IHH prevents pubertal ovarian stimulation, but anti-Müllerian hormone (AMH) and antral follicle count (AFC) have not been studied.

    Objectives: (1) To compare, in IHH vs controls, AMH, ovarian volume (OV), and AFC. Read More

    17α-HYDROXYLASE/17, 20-LYASE DEFICIENCY: CLINICAL AND MOLECULAR CHARACTERIZATION OF EIGHT CHINESE PATIENTS.
    Endocr Pract 2017 May 22;23(5):576-582. Epub 2017 Feb 22.
    Objective: 17α-hydroxylase/17, 20-lyase deficiency (17OHD) is caused by mutations in the cytochrome P450 17A1 (CYP17A1) gene. To better understand 17OHD, a rare disease, we described the clinical features and performed CYP17A1 gene analysis in 8 affected Chinese patients.

    Methods: Patients with complete (7/8) or partial (1/8) 17OHD were derived from 6 families. Read More

    Global Medical Affairs, MSD Pharmaceuticals Private Limited, 10th Floor, Platina Building, C-59, G-Block, Bandra Kurla Complex, Mumbai, Maharashtra, India.
    Background: A high prevalence of hypogonadism in men with Type-2 diabetes mellitus (T2DM) has been reported worldwide.

    Objectives: To evaluate the prevalence of hypogonadism in Indian males with T2DM and assess the primary and secondary hypogonadism along with androgen deficiency.

    Materials And Methods: In this cross-sectional study, 900 men with T2DM were evaluated using androgen deficiency in aging male questionnaire. Read More
