Understanding spermatogenesis is a prerequisite for treatment [PDF]
Reproductive Biology and Endocrinology, 2003 Throughout spermatogenesis multiplication, maturation and differentiation of germ cells results in the formation of the male gamete. The understanding of spermatogenesis needs detailed informations about the organization of the germinal epithelium, the ...

Ubiquitin-Proteasome System–Regulated Protein Degradation in Spermatogenesis
Cells, 2022 Spermatogenesis is a prolonged and highly ordered physiological process that produces haploid male germ cells through more than 40 steps and experiences dramatic morphological and cellular transformations.

Annales d'Endocrinologie, 2022 International audienceMale infertility contributes to 50% of all cases of infertility. The main cause is low quality and quantity of sperm. In humans, spermatogenesis starts at the beginning of puberty and lasts lifelong.

The Potential Role of Deubiquitinating Enzymes (DUBs) in Male Fertility [PDF]
BiomoleculesUbiquitination dynamically regulates critical cellular processes, including cell cycle progression, apoptosis, DNA repair, and chromatin remodeling. Deubiquitinating enzymes (DUBs) negatively regulate protein ubiquitination and are equally important for ...

Advances in research on RNA N-6-methyladenosine(m6A) modification related enzymes in mammalian spermatogenesis [PDF]
Jichu yixue yu linchuang, 2023 N-6-methyladenosine(m6A) has been well-known to be a type of RNA epigenetic modification over the past decade. The m6A modification enzymes include “Writers” (METTL3/14/WTAP, etc.),“Erasers” (FTO and ALKBH5) and “Readers” (YTHDC1/2,YTHDF1/2/3, etc ...

Current Biology, 2017 Most organisms consist of two cell lineages - somatic cells and germ cells. The former are required for the current generation, and the latter create offspring. Male and female germ cells are usually produced during spermatogenesis and oogenesis, which take place in the testis and the ovary, respectively. Spermatogenesis involves the differentiation of

Human Reproduction, 1998 Spermatogenesis is a complex process involving mitotic cell division, meiosis and the process of spermiogenesis. The regulation of spermatogenesis involves both endocrine and paracrine mechanisms. The endocrine stimulation of spermatogenesis involves both follicle stimulating hormone (FSH) and luteinizing hormone, the latter acting through the ...

Functions of somatic cells for spermatogenesis in stallions
Journal of Animal Science and Technology, 2022 Spermatogenesis and testis development are highly structured physiological processes responsible for post-pubertal fertility in stallions. Spermatogenesis comprises spermatocytogenesis, meiosis, and spermiogenesis.
