Male Reproductive System - Seminiferous Tubule

Wall of the seminiferous tubule. The seminiferous tubule is isolated from the blood by a blood testis barrier. Both the basal lamina and the pale-stained Sertoli cells participate in this barrier. Sitting on the basal lamina are spermatogonia. These germ

Differential expression of apoptotic proteins in seminiferous tubule cells of adult rats by neonatal exposure to 6-n-propyl-2-thiouracil (PTU), a thyroid disrupting chemical [PDF]

, 2017
634-641Role of thyroid hormones in the development of testis is still a matter of debate. Previously, we have shown that spermatogenesis is impaired in adult rats by 6-n-propyl-2-thiouracil (PTU)-induced neonatal hypothyroidism.

Children Born Using Ejaculated Sperm From Men With Klinefelter Syndrome. Is Sperm Production Associated With Testicular Volume?

Andrology, EarlyView.
ABSTRACT Background A large number of children have been born using testicular sperm from men with Klinefelter syndrome (KS), whereas reports of children conceived using ejaculated sperm are rare. Objective To review all published cases of children conceived using ejaculated sperm from men with KS, assess their health and karyotype, and evaluate ...

Spatiotemporal Expression of ARRDC5 in Mammalian Spermatogenesis

Andrology, EarlyView.
ABSTRACT Background Spermiogenesis is the final phase of sperm development during which haploid round spermatids transform into specialized spermatozoa and occurs across distinct stages of sperm production in the seminiferous epithelium. Abnormalities in this process lead to malformations and an inability of sperm to fertilize eggs.

Male Mice Heterozygous for Protamine 1 and Protamine 2 Are Infertile, Displaying Sperm Damage and Retention of Protamine 2 Precursors, Transition Proteins, and Histones

Andrology, EarlyView.
ABSTRACT Background During spermiogenesis, protamines (PRMs) replace histones to hypercondense and protect sperm DNA. Rodents and primates express two PRMs (PRM1 and PRM2). Alterations of species‐specific PRM ratios are associated with sub‐ or infertility in mice and humans.

Sox9 downregulation in non-obstructive azoospermia by UTF1 and mediator role of POU5F1

BMC Research Notes
Background Spermatogenesis is the process of producing mature sperm from Spermatogonial stem cells (SSCs) and this process requires a complex cooperation of different types of somatic and germ cells.

The Impact of Common Medications on Male Fertility: An Updated Systematic Review

Andrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...
