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.

Mouse sperm delivery via cauda epididymis without transport medium

, 2016
This study was aimed to investigate the effects of room temperature (RT, 20-25 oC) and absence of medium during cauda epididymis transport on spermatozoa quality, fertility and embryo development.

Successful ICSI in Mice Using Caput Epididymal Spermatozoa

Frontiers in Cell and Developmental Biology, 2019
Spermatozoa undergo their last phase of spermiogenesis, known as maturation, as they pass through the epididymis. A recent report indicates that mouse immature spermatozoa retrieved from the caput epididymis for intracytoplasmic sperm injection (ICSI ...

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.

Expression of NELL2/NICOL-ROS1 lumicrine signaling-related molecules in the human male reproductive tract

Reproductive Biology and Endocrinology
The maturation of spermatozoa is a regulated process, influenced by genes expressing essential secreted proteins in the proximal epididymis. Recent genetic studies in rodents have identified the non-sex steroidal molecular signals that regulate gene ...
