Preventive online and offline health management intervention in polycystic ovary syndrome.

World J Clin Cases 2022 Apr;10(10):3060-3068

Dermatological Department, Beijing Hospital of Traditional Chinese Medicine, Capital Medical University, Beijing 101100, China.

Background: Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism, hyperinsulinemia, ovarian polycystic changes, and irregular ovulation, often occurring in women of childbearing age for whom it can be a cause of infertility. Hypothalamus-pituitary-ovarian axis dysregulation is important in the pathogenesis of PCOS and the associated chronic excess of sex hormones can lead to cardiovascular and cerebrovascular diseases, diabetes, and malignancies such as endometrial cancer, and breast cancer. At present, most scholars agree that lifestyle interventions in conjunction with drug treatment can help PCOS patients achieve their goals of successful pregnancy and childbirth. Read More

Puberty induction with recombinant gonadotropin: What impact on future fertility?

Ann Endocrinol (Paris) 2022 Jun 15;83(3):159-163. Epub 2022 Apr 15.

Endocrinologie et diabétologie pédiatrie, Hôpital Bicêtre, AP-HP, Le Kremlin-Bicêtre, France.

Congenital hypogonadotropic hypogonadism (CHH) is a group of rare diseases characterized by inadequate secretion of the gonadotropins LH (luteinizing hormone) and FSH (follicle stimulating hormone) during the physiological activation periods of the gonadotropic axis. The disease? (anomaly) is present from fetal life and usually persists throughout life. Clinically, hypogonadotropic hypogonadism is associated with neonatal clinical signs (micropenis, cryptorchidism in boys in about half of the cases). Read More

Characterization of pituitary stem/progenitor cell populations in spontaneous dwarf rats.

J Vet Med Sci 2022 May 5;84(5):680-688. Epub 2022 Apr 5.

Laboratory of Veterinary Biochemistry, Joint Department of Veterinary Medicine, Faculty of Agriculture, Tottori University, Tottori, Japan.

Spontaneous dwarf rat (SDR) is a primary experimental animal model for the study of pituitary dwarfism with a point mutation in the Gh gene encoding growth hormone (GH). In previous studies, SDR has been reported to be associated with the GH deficiency as well as combined hormone deficiencies, the cause of which is unknown. In this study, we focused on the characteristics of pituitary stem/progenitor cell populations, which are a source of hormone-producing cells, in SDR. Read More

A Novel Homozygous CYP19A1 Gene Mutation Causing Aromatase Deficiency.

Cureus 2022 Feb 9;14(2):e22059. Epub 2022 Feb 9.

Department of Endocrinology, Nil Ratan Sircar Medical College, Kolkata, IND.

Aromatase deficiency is a rare autosomal recessive disorder and its exact prevalence is not known. Aromatase enzyme catalyzes the conversion of androgens to estrogens in gonadal and extra-gonadal tissues. Deficiency of aromatase enzyme can lead to ambiguous genitalia in a female child and maternal virilization during pregnancy due to raised androgen levels in the mother. Read More

Panhypopituitarism Presents As Amenorrhea Secondary to Post Traumatic Stress Disorder in a 33-Year-Old Patient: A Case Report.

Cureus 2022 Mar 3;14(3):e22812. Epub 2022 Mar 3.

Medicine, New York Institute of Technology College of Osteopathic Medicine (NYITCOM), Old Westbury, USA.

Hormonal derangements should be suspected whenever a patient experiences amenorrhea with no abnormal physical exam findings. Clinical suspicion is increased if she also reports psychological trauma that could affect her nervous system and, by association, her hormones since the pituitary gland is present in the brain. Additional exams that aid in the diagnosis of amenorrhea include a variety of blood panels and imaging scans. Read More

Leptin secreted from testicular microenvironment modulates hedgehog signaling to augment the endogenous function of Leydig cells.

Cell Death Dis 2022 03 4;13(3):208. Epub 2022 Mar 4.

Department of Urology, Miller School of Medicine, University of Miami, Miami, FL, USA.

Although testosterone deficiency (TD) may be present in one out of five men 40 years or older, the factors responsible for TD remain largely unknown. Leydig stem cells (LSCs) differentiate into adult Leydig cells (ALC) and produce testosterone in the testes under the pulsatile control of luteinizing hormone (LH) from the pituitary gland. However, recent studies have suggested that the testicular microenvironment (TME), which is comprised of Sertoli and peritubular myoid cells (PMC), plays an instrumental role in LSC differentiation and testosterone production under the regulation of the desert hedgehog signaling pathway (DHH).

U-shaped association between prevalence of secondary hypogonadism and body mass index: a retrospective analysis of men with testosterone deficiency.

Int J Impot Res 2022 Feb 3. Epub 2022 Feb 3.

Department of Urology, University of Miami Miller School of Medicine, Miami, FL, USA.

The prevalence of both obesity and hypogonadism in the United States has increased over the past two decades. While prior studies have shown an association between obesity and secondary hypogonadism-low testosterone and luteinizing hormone-few have used a large enough sample size to determine prevalence at each body mass index class. We aimed to compare rates of secondary hypogonadism among body mass index classes by constructing a retrospective database with men who had their body mass index, morning testosterone and luteinizing hormone levels measured during a visit to a urology clinic at a tertiary academic medical center between 2011-2020.

Gonadotropin-releasing hormone-secreting neuron development and function: an update.

Minerva Endocrinol (Torino) 2022 Mar 1;47(1):58-69. Epub 2022 Feb 1.

Department of Pharmacological and Biomolecular Sciences, University of Milan, Milan, Italy -

The coordinated and pulsatile secretion of gonadotropin-releasing hormone (GnRH) plays a central role in vertebrate reproductive function. The development of the hypothalamo-pituitary-gonadal (HPG) axis is characterized by a complex network of molecular signals that controls, at first, migration of the GnRH neurons along the nose, through the cribriform plate, up to the frontal lobe. This migratory process is orchestrated by several factors including anosmin-1, polysialylated form of the neural cell adhesion molecule, γ-amino butyric acid, hepatocyte growth factor, chemokines, cytokines and semaphorins.

Rodolfo A Rey

Ther Adv Endocrinol Metab 2022 5;13:20420188211065660. Epub 2022 Jan 5.

Departamento de Histología, Embriología, Biología Celular y Genética, Facultad de Medicina, Universidad de Buenos Aires, Buenos Aires, Argentina.

Clinical manifestations and the need for treatment varies according to age in males with hypogonadism. Early foetal-onset hypogonadism results in disorders of sex development (DSD) presenting with undervirilised genitalia whereas hypogonadism established later in foetal life presents with micropenis, cryptorchidism and/or micro-orchidism. After the period of neonatal activation of the gonadal axis has waned, the diagnosis of hypogonadism is challenging because androgen deficiency is not apparent until the age of puberty. Read More

Warren Alpert Medical School, Brown University, 272 George St., Providence, RI 02906, USA.

The pituitary is an organ of dual provenance: the anterior lobe is epithelial in origin, whereas the posterior lobe derives from the neural ectoderm. The pituitary gland is a pivotal element of the axis regulating reproductive function in mammals. It collects signals from the hypothalamus, and by secreting gonadotropins (FSH and LH) it stimulates the ovary into cyclic activity resulting in a menstrual cycle and in ovulation. Read More

Clomiphene citrate for men with hypogonadism: a systematic review and meta-analysis.

Andrology 2022 03 8;10(3):451-469. Epub 2022 Jan 8.

Department of Urology, University Medical Centre Utrecht, Utrecht, The Netherlands.

Background: Male hypogonadism is a clinical and biochemical androgen insufficiency syndrome, becoming more prevalent with age. Exogenous testosterone is first-choice therapy, with several side effects, including negative feedback of the hypothalamic-pituitary-gonadal axis, resulting in suppression of intratesticular testosterone production and spermatogenesis. To preserve these testicular functions while treating male hypogonadism, clomiphene citrate is used as off-label therapy. Read More
