Comparing the role of anti-M üllerian hormone as a marker of FSH action in male and female fertility.

Comparing the role of anti-Müllerian hormone as a marker of FSH action in male and female fertility. Expert Rev Endocrinol Metab. 2019 Mar 04;:1-12 Authors: Urrutia M, Grinspon RP, Rey RA Abstract INTRODUCTION: Originally limited to the assessment of disorders of sex development, anti-Müllerian hormone (AMH) measurement has more recently been extended to several conditions affecting the reproductive axis in males and females. Follicle-stimulating hormone (FSH) regulation of gonadal function has been extensively studied, but its role on AMH production has been explored only recently. Areas covered: We addressed the relationship between FSH action on the gonads and the usefulness of AMH as a marker in conditions affecting the reproductive axis. Expert opinion: Sertoli cells are the most active cell population in the prepubertal testis. Serum AMH is an excellent marker of FSH action on Sertoli cell proliferation and function in patients with hypogonadotropic hypogonadism. Low serum AMH is expected to predict low sperm production and prompts initial FSH treatment followed by human chorionic gonadotropin (hCG) or luteinizing hormone (LH) addition. Gonadotropin treatment may be more effective if installed to mimic the postnatal activation stage of the hypothalamic-pituitary-testicular axis. In females, AMH secretion by small antral follicles is stimulated by FSH. Elevated AMH indicates increased follicle numbers and should be considered as a potential...

Authors: Cho CL, Esteves SC, Agarwal A Abstract Varicoceles exert deleterious effect on testicular function. The condition has been associated with male infertility, testicular hypotrophy and pain. These comprises the common indications for varicocele repair currently. Significant improvement in semen parameters and pregnancy outcomes had been suggested by reports decades ago. However, selection of the best candidates remains an issue since not all patients respond positively to treatment. Consensus has been reached in recent decade after the publication of a series of meta-analyses. Significant improvement in preg...

Conclusion: We report the first homozygous nonsense mutation in theGNRHR gene (chr4: g. 68619942G#x3e;A, c.112C#x3e;T, p. Arg38*) that is associated with familial nCHH. Hence, our study displayed a good correlation of the genotype and phenotype of nCHH patients.Horm Res Paediatr 2019;91:1 –8

An appropriate diagnostic evaluation is essential for the most appropriate treatment to be performed. Currently, macroprolactinemia is the third most frequent cause of non-physiological hyperprolactinemia after drugs and prolactinomas. Up to 40% of macroprolactinemic patients may present with hypogonadism symptoms, infertility and/or galactorrhea. Thus, the screening for macroprolactin is indicated not only for asymptomatic subjects but also for those without an obvious cause for their prolactin (PRL) elevation. Before submitting patients to macroprolactin screening and pituitary magnetic resonance imaging (MRI), one shoul...

by Iyad H. Manaserh, Lakshmikanth Chikkamenahalli, Samyuktha Ravi, Prabhatchandra R. Dube, Joshua J. Park, Jennifer W. Hill Insulin resistance and obesity are associated with reduced gonadotropin-releasing hormone (GnRH) release and infertility. Mice that lack insulin receptors (IRs) throughout development in both neuronal and non-neuronal brain cells are known to exhibit subfertility due to hypogonadotropic hypogonadi sm. However, attempts to recapitulate this phenotype by targeting specific neurons have failed. To determine whether astrocytic insulin sensing plays a role in the regulation of fertility, we generated mice...

Klinefelter syndrome (KS), in which subjects have additional copies of X chromosomes, is the most common male sex chromosome abnormality, with a prevalence of 1 in 660 and an incidence of about 1 in 500-700 newborns. Its sign and symptoms include infertility, generally low testosterone levels, and an increased prevalence of obesity and metabolic syndrome. Epicardial fat thickness (EFT) reflects visceral adiposity rather than general obesity.

CONCLUSION: We suggest that serum levels of IGF-I should be watched in children with poor development of sexual organs, although it remains to be investigated whether GH in some cases should be added to sex steroids in management of hypogonadism in pubertal children, e.g. in boys with micro-penis.

Muffin tops, man boobs, and bagel bumps: These are among the varied and perverse ways that the hormonal distortions inflicted on unwitting humans who consume the seeds of grasses, i.e., grains, show themselves. In our modern world filled with thousands of processed foods, there are plenty of landmines for health. Gummy bears and gumdrops will rot teeth, for instance. Indulge in a handful of dried prunes and you’ll have to schedule a substantial portion of your day on the toilet due to bowel irritants. But only wheat and grains are associated with a wide swath of health problems that range from autoimmune disease to m...

Because it has become such a frequent item in everyday meals, suggesting that something so commonplace must be fine, people often ask: Is wheat really that bad? Let’s therefore catalog the health conditions that are associated with wheat consumption. Health conditions we know with 100% certainty are caused by consumption of wheat and related grains: Celiac disease, dermatitis herpetiformis, cerebellar ataxia, “idiopathic” peripheral neuropathy, temporal lobe seizures, gluten encephalopathy, type 1 diabetes, rheumatoid arthritis, autoimmune hepatitis, autoimmune pancreatitis, tooth decay Health conditions ...

Authors: Young J, Xu C, Papadakis GE, Acierno JS, Maione L, Hietamäki J, Raivio T, Pitteloud N Abstract The initiation and maintenance of reproductive capacity in humans is dependent upon pulsatile secretion of the hypothalamic hormone gonadtropin-releasing hormone, GnRH. Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder that results from the failure of the normal episodic GnRH secretion, leading to delayed puberty and infertility. CHH can be associated with an absent sense of smell, also termed Kallmann syndrome, or with other anomalies. CHH is characterized by rich genetic heterogeneity, with...
