Summary
Genetic variants are a key cause of male infertility, particularly impacting sperm motility. This review focuses on genetic defects in radial spoke complexes, crucial for sperm tail function and male fertility.
Area of Science:
- Reproductive Biology
- Genetics
- Molecular Biology
Background:
- Male infertility affects global reproductive health, with motility defects common in infertile males.
- Idiopathic male infertility accounts for 15-40% of cases, with unresolved causal factors.
- Genetic variants are increasingly recognized as significant contributors to male infertility.
Purpose of the Study:
- To review current knowledge on genetic variants causing male infertility.
- To highlight the role of radial spoke complex proteins in sperm motility and fertility.
Main Methods:
- Literature review of genomic analyses and genetic variant studies.
- Focus on proteins within the radial spoke complexes critical for sperm tail structure and function.
Main Results:
- Diverse genetic variants have been identified as causes of idiopathic male infertility.
- Defects in radial spoke complex proteins are directly linked to sperm motility issues.
Conclusions:
- Genetic factors, especially those affecting radial spoke complexes, are crucial for male fertility.
- Understanding these genetic underpinnings is vital for diagnosing and potentially treating male infertility.

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...
01:41Spermatogenesis
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...
01:22Spermatogenesis
Spermatogenesis is a complex process that involves the development of sperm cells from undifferentiated stem cells in the seminiferous tubules of the testes. The process is essential for the production of mature and functional sperm cells that are capable of fertilizing an egg.
The process of spermatogenesis can be divided into mitosis, meiosis, and spermiogenesis. During mitosis, the spermatogonia or stem cells divide to produce two identical daughter cells, type A and B spermatogonia. Type-A...

01:43Sex-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.
02:19The 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,...

02:32X and Y Chromosomes
Among mammals, the gender of an organism is determined by the sex chromosomes. Humans have two sex chromosomes, X and Y. Every human diploid cell has 22 pairs of autosomes and one pair of sex chromosomes. A human female has two X chromosomes, while a male has one X chromosome and one Y chromosome.
The germline cells such as egg and sperm cells carry only half the number of chromosomes, i.e., 22 autosomes and one sex chromosome. All eggs have an X chromosome, while sperm cells can carry an X or...
