INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence

Andrology, EarlyView.
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

Healthy Aging Men Do Not Suffer From Relevant Limitations of Their Reproductive Functions

Andrology, EarlyView.
Abstract Background While metabolic disorders are well‐established contributors to testosterone decline and erectile dysfunction (ED), little is known about the natural progression of reproductive parameters in healthy aging men. Objectives This study aimed to evaluate longitudinal changes in reproductive parameters and sought to determine the ...

Cryopreservation of Spermatozoa Prior and Post‐Orchiectomy in Patients With Testicular Germ Cell Cancer—Does the Timing Matter?

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell cancer (TGCC) is the most frequent malignancy in young men of reproductive age. According to guidelines, semen cryopreservation should be performed prior to orchiectomy. Lack of time and local facilities as well as mental pressure are challenges in terms of fertility preservation before surgery.

Comprehensive Quantification of Oligoasthenozoospermia Induced by Obesity, Reproductive Toxicants, and Their Combination in Rat Models

Andrology, EarlyView.
ABSTRACT Background Oligoasthenozoospermia is a leading cause of male infertility and has been increasingly associated with the global surge in obesity and exposure to reproductive toxicants. Despite extensive research on each factor individually, their combined pathological effects remain poorly understood.

اثر عصاره الکلی گیاه آب بشقابی بر غلظت سرمی تستوسترون، FSH و LH در موش صحرایی نر نژاد ویستار [PDF]

مجله دانشگاه علوم پزشکی سبزوار, 1970
زمینه و هدف: تعداد اسپرم ها و قدرت باروری آن ها به سطح هورمون های آندروژنی خون وابسته است. بنابراین احتمال می رود که عصاره گیاه آب بشقابی بر سطح هورمون های موثر در روند اسپرماتوژنز اثر بگذارد. به همین منظور، مطالعه ای با هدف تعیین اثر عصاره الکلی گیاه آب

Parental Educational Attainment at Birth and Biomarkers of Male Fecundity: A Study From the Danish National Birth Cohort

Andrology, EarlyView.
ABSTRACT Background Low parental education is associated with poorer offspring health, but its influence on male fecundity remains unclear. Objective To study the association between parental educational attainment at birth and biomarkers of male fecundity in young men and to explore whether this association is mediated by maternal smoking in pregnancy

The satiety hormone cholecystokinin gates reproduction in fish by controlling gonadotropin secretion

eLife
Life histories of oviparous species dictate high metabolic investment in the process of gonadal development leading to ovulation. In vertebrates, these two distinct processes are controlled by the gonadotropins follicle-stimulating hormone (FSH) and ...

Macro-FSH is a rare cause of inappropriately high FSH concentrations

Endocrinology, Diabetes & Metabolism Case Reports
Summary Assessment of hormone concentrations can be subjected to laboratory pitfalls. Macro-hormones are hormone–autoantibody complexes which are cleared slowly from circulation and cause a false elevation in hormones’ concentrations. Macro-prolactin and macro-thyroid-stimulating hormone (TSH) are most frequently encountered while macro-follicle ...

Homo sapiens, industrialisation and the environmental mismatch hypothesis

Biological Reviews, EarlyView.
ABSTRACT For the vast majority of the evolutionary history of Homo sapiens, a range of natural environments defined the parameters within which selection shaped human biology. Although human‐induced alterations to the terrestrial biosphere have been evident for over 10,000 years, the pace and scale of change has accelerated dramatically since the onset
