[Ageing of the spermatogenesis system]
Summary
Ageing reduces male germ cell development and function. This review examines age-related changes in stem spermatogonial cells and their niche, including in senescence-accelerated mutant mice.
Area of Science:
- Reproductive Biology
- Gerontology
- Cellular Biology
Background:
- Male reproductive function declines with age.
- Spermatogenesis, the process of sperm production, is particularly sensitive to ageing.
- Understanding these changes is crucial for reproductive health in aging populations.
Purpose of the Study:
- To review and synthesize current data on the effects of ageing on male germ cell development.
- To investigate the causes of reduced spermatogenesis in later life stages.
- To analyze age-specific alterations in stem spermatogonial cells and their microenvironment.
Main Methods:
- Literature review of studies on ageing and male germ cell development.
- Analysis of age-related changes in stem spermatogonial cell structure and function.
- Examination of the stem cell niche in aging male reproductive systems.
- Comparative study of senescence-accelerated mutant mice (SAM) to understand accelerated ageing effects.
Main Results:
- Ageing significantly impacts the structural-functional integrity of stem spermatogonial cells.
- The stem cell niche undergoes age-specific changes that affect spermatogenesis.
- Senescence-accelerated mutant mice exhibit distinct alterations in their spermatogenic systems due to accelerated ageing.
Conclusions:
- Ageing poses a significant challenge to male fertility through detrimental effects on germ cells and their supporting environment.
- Targeting stem spermatogonial cells and their niche may offer therapeutic strategies for age-related male infertility.
- Further research into senescence-accelerated models can provide insights into mitigating age-related reproductive decline.

Spermatogenesis
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...

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...
Menopause
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...
Sperm Transport
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
The maturation phase occurs in the epididymis, where sperm...

Oogenesis
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
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...
