[Testosterone-inhibin interaction in male sterility]
Problemy Endokrinologii
|January 1, 1991
Summary
Hormonal imbalances, including low testosterone and high estradiol, are linked to male infertility. High inhibin activity may disrupt sperm production and mobility, contributing to sterility.
Area of Science:
- Endocrinology
- Reproductive Medicine
- Andrology
Context:
- Investigated hormonal profiles in men under 40 experiencing secretory sterility.
- Analyzed hormones in peripheral blood and seminal fluid.
- Compared hormonal levels between healthy individuals and infertile patients.
Purpose:
- To elucidate the role of peripheral blood and seminal fluid hormones in the pathogenesis of male sterility.
- To establish correlations between specific hormone levels and sperm parameters.
Summary:
- Sterile men exhibited decreased peripheral testosterone and elevated estradiol. Luteinizing hormone (LH) and prolactin levels were also increased.
- Testosterone was lower in seminal plasma than peripheral blood, while inhibin activity was higher in seminal plasma.
- Positive correlation found between blood testosterone and sperm concentration/motility. Inhibin activity showed complex correlations with sperm parameters, potentially indicating sterility.
Impact:
- Identifies specific hormonal dysregulations associated with male infertility.
- Suggests inhibin activity as a potential key factor in sterility pathogenesis.
- Provides insights for diagnosing and potentially treating male reproductive disorders.

01:41Spermatogenesis
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...
01:30Enzyme Inhibition
Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.
01:52Eukaryotic Transcription Inhibitors
Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.

01:22Birth Control Methods
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although vasectomy...
01:23Infertility in Males
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
01:28Infertility in Females
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
