In recent years, a number of studies focused on the role of epigenetics, including DNA methylation, in spermatogenesis and male infertility. We aimed to provide an overview of the knowledge concerning the gene and genome methylation and its regulation during spermatogenesis, specifically in the context of male infertility etiopathogenesis. Overall, the findings support the hypothesis that
Spermatogenesis is a vital biological process. It is the means by which male gametes are produced. Through meiosis, it permits genetic recombination to increase genetic variations and thereby improve the gene pool. Any disturbance or interference in this process could lead to reduced fertility among males.

Solution. The sperm cells are the haploid gametes which are produced in the male. There are different parts of the sperm cell. (a) Acrosome: This structure contains enzymes used for penetrating the female egg. (b) Nucleus: There is the genetic material which is a haploid genome because it contains only one copy of each chromosome.
What is the scrotum and where is it located? - A hairy sac of skin & connective tissue that hangs outside the pelvic cavity at the root of the penis. - Divided by a midline septum which provides a compartment for each testis. Describe the function of the scrotum. The scrotum helps regulate the temperature of the testes. - sperm survival
During spermatogenesis, many cellular events ensure that diploid spermatogonia (2n) can become haploid spermatids (1n). Some of these events are described in (a–c). (a) Mitosis. Type A spermatogonia undergo either self-renewing replication or differentiation into intermediate and type B spermatogonia.
Spermatogenesis is the complete process of the production of the sperm cells from the cells of the germinal epithelium of males. Spermiogenesis is the final differentiation and maturation process of the spermatids into sperm cells. The main difference between spermatogenesis and spermiogenesis is the mechanism of each process in the production
The detailed process of spermatogenesis is reviewed in the other chapters. The effects of Leydig cell on spermatogenesis mostly act via secreting hormones, mainly androgen. The importance of androgen for the regulation of spermatogenesis is proven by pharmacological treatment of androgens and the conditional knockout androgen receptor.
