Insights

Spermatogenic arrest, a cause of infertility in men, is linked to genetic variants affecting cell division and germline development. Understanding these variants can help develop new treatments for non-obstructive azoospermia.

Area of Science:

  • Reproductive Biology
  • Genetics
  • Male Infertility

Background:

  • Spermatogenic arrest causes non-obstructive azoospermia (NOA) in 10-15% of infertile men.
  • This arrest results from disruptions in premeiotic, meiotic, or postmeiotic germ cell progression.

Purpose of the Study:

  • To review genetic variants associated with spermatogenic arrest in NOA.
  • To discuss the utility of gene panel screening for identifying genetic causes of NOA.

Main Methods:

  • Comprehensive review of genetic variants identified through genome/exome sequencing in NOA patients.
  • Analysis of knockout mouse models for genes implicated in spermatogenic failure.
  • Discussion on the application of gene panel-based screening.

Main Results:

  • Numerous genetic variants have been identified in genes crucial for mitosis, meiosis, and germline differentiation.
  • Knockout mouse models have been developed to study the functional impact of these variants.
  • Gene panel screening shows promise for diagnosing NOA cases.

Conclusions:

  • Genetic variants play a significant role in spermatogenic arrest and NOA.
  • Further research into these variants and gene panel screening can advance diagnostic and therapeutic strategies for male infertility.

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...

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...

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....

Sex-linked Disorders01:43

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Genetic Variation01:25

Genetic Variation

Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles,...

Nondisjunction01:21

Nondisjunction

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers.  Nondisjunction is common during anaphase I or anaphase II of meiosis.  Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...
