USP7 and SET9 Expression in The Oligospermic Human Semen: A Case-Control Study [PDF]

International Journal of Fertility and Sterility, 2022
Background: Oligospermia is defined as a less than 15 million per milliliter sperm in each ejaculation of semen. Proper and complete spermatogenesis requires the expression of a large number of genes.

Association of CATSPER1, SPATA16 and TEX11 genes polymorphism with idiopathic azoospermia and oligospermia risk in Iranian population

BMC Medical Genomics, 2022
Male infertility is a heterogeneous disease which can occur due to spermatogenesis defects. The idiopathic azoospermia and oligospermia are the common cause of male infertility with unknown underlying molecular mechanisms.

An effective method for establishing animal models of azoospermia and oligospermia

Andrologia, 2021
The current study aims to develop a validated animal model to predict successful spermatogenesis retrieval in azoospermia and oligospermia men. Thirty‐two mice were equally divided into 4 groups: control, scrotal hyperthermia (15 times), scrotal ...
