The hormones involved in the control of spermatogenesis are the following: Testosterone is secreted by Leydig cells of the testis. One of its functions in this process is to activate genes that promote the differentiation of spermatogonia. FSH (follicle-stimulating hormone) is secreted by the pituitary gland and acts on the testicle, in the
Bookshelf ID: NBK26914. In most species, there are just two types of gamete, and they are radically different. The egg is among the largest cells in an organism, while the sperm (spermatozoon, plural spermatozoa) is often the smallest. The egg and the sperm are optimized in opposite ways for the propagation of the genes they carry.
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
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.
Abstract. FSH and testosterone (T) secretion are essential for the successful completion of spermatogenesis. Because there are no receptors for FSH or testosterone on germ cells, there are intermediate steps in this action, the nature of which are unknown. However, as the Sertoli cell contains receptors for both FSH and T, it is likely that
The most common histological classifications are: 1. “Mixed atrophy” (tubules with varying stages of spermatogenesis). 2. Various types of “spermatogenic arrest” (such as round spermatid or meiotic arrest, MA, Fig. 2 b, these stages being the most advanced that can be found). 3.
Spermatogenesis is the process of formation of haploid male gametes or sperms or spermatozoa from male germ cells or spermatogonia. Sperms are formed in the seminiferous tubules of testes, the male reproductive organ. Spermatogenesis is important for maintaining the number of chromosomes in the offsprings.
