The Y Chromosome Determines Maleness02:19

The Y Chromosome Determines Maleness

8.9K
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....

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

3.9K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

The Ratio of X Chromosome to Autosomes02:45

The Ratio of X Chromosome to Autosomes

10.1K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.  
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Disorders of the Male Reproductive System

5.4K
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....

Infertility in Males01:23

Infertility in Males

684
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...

Development of the Sexual Organs in the Embryo and Fetus01:15

Development of the Sexual Organs in the Embryo and Fetus

5.0K
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the...

Area of Science:

  • Endocrinology
  • Genetics
  • Reproductive Medicine

Background:

  • Androgen insensitivity syndrome (AIS) is a frequent cause of disorders of sex development, arising from androgen receptor (AR) dysfunction.
  • The clinical presentation of AIS correlates with the level of residual AR activity.
  • Understanding the molecular actions of androgens and AR gene mutations is crucial for comprehending AIS pathogenesis.

Purpose of the Study:

  • To review the molecular mechanisms of androgen action and the spectrum of AR gene mutations.
  • To elucidate the pathogenesis of complete and partial forms of Androgen Insensitivity Syndrome.
  • To highlight the importance of a multidisciplinary approach in the clinical management of AIS.

Main Methods:

  • Review of existing literature on androgen receptor function, gene mutations, and clinical management of AIS.
  • Analysis of the relationship between AR activity and AIS phenotype.
  • Discussion of current and future research directions in AR dysfunction and associated disorders of sex development.

Main Results:

  • AR dysfunction is the primary cause of AIS, with varying phenotypes based on residual AR activity.
  • Hormone replacement therapy is necessary post-gonadectomy.
  • Patients retaining gonads face germ cell tumor risks, with potential for new tumor markers.

Conclusions:

  • The role of AR dysfunction in complete AIS is established, while its contribution to partial AIS requires further investigation.
  • A multidisciplinary approach is essential for comprehensive AIS patient care.
  • Further research into AR mechanisms and associated proteins is needed for partial AIS and other disorders of sex development.
