Insights

Anti-Müllerian hormone (AMH) is crucial for male fetal development and regulates Leydig cell function. AMH also serves as a key indicator for prepubertal testicular function and adult female fertility.

Area of Science:

  • Reproductive Endocrinology
  • Developmental Biology

Background:

  • Anti-Müllerian hormone (AMH), also known as Müllerian inhibiting substance (MIS), is produced by Sertoli and granulosa cells.
  • It plays a vital role in male fetal development by inducing Müllerian duct regression and influences Leydig cell steroidogenesis and follicular development.

Purpose of the Study:

  • To elucidate the physiological roles and regulatory mechanisms of AMH.
  • To highlight AMH's significance as a biomarker in reproductive health.

Main Methods:

  • Review of existing literature on AMH.
  • Analysis of AMH's signaling pathways and genetic regulation.

Main Results:

  • AMH signals via specific serine/threonine kinase receptors, interacting with the bone morphogenetic pathway.
  • AMH production is positively regulated by SF1, SOX9, and FSH, and negatively by testosterone.
  • Defects in AMH signaling lead to persistent Müllerian derivatives in males.

Conclusions:

  • AMH is essential for normal male sexual differentiation.
  • AMH is a reliable marker for assessing prepubertal testicular function and female ovarian reserve.

The Y Chromosome Determines Maleness02:19

The Y Chromosome Determines Maleness

The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size. Today,...
Testes: Histology01:27

Testes: Histology

A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.
The spermatogenic cells, responsible for producing sperm, are...
Infertility in Males01:23

Infertility 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...

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...
Hormonal Regulation01:40

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.
Spermatogenesis01:41

Spermatogenesis

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...
