Following insemination of spermatozoa pre-ovulation, the mammalian oviduct ensures, by
the formation of a functional sperm reservoir (SR), that suitable (low) numbers of viable and …

In the pig, a functional tubal sperm reservoir (SR) is established before ovulation to ensure
availability of suitable numbers of viable spermatozoa for fertilization. The boar's large …

The testis is an important male reproductive organ, which ensures reproductive function via
the secretion of testosterone and the generation of spermatozoa. Testis development begins …

Fertilization success cannot be attributed solely to the absolute number of vital, motile,
morphologically normal spermatozoa inseminated into the female but more especially to …

Whole-cell voltage clamp of mammalian spermatozoa was first achieved in 2006. This
technical advance, combined with genetic deletion strategies, makes unambiguous …

For sperm to successfully fertilize an oocyte, it needs to pass through certain steps prior to,
during and after initial recognition of the zona pellucida (ZP). During capacitation, the …

Sperm migration through the female genital tract is not a quiet journey. Uterine contractions
quickly operate a drastic selection, leading to a very restrictive number of sperm reaching …

Research over the past 3 decades has caused a major shift in the way that the oviduct, or
fallopian tube, is perceived. Previously, it was regarded as little more than the anatomic site …

A reliable, easy to assess marker for fertility in agricultural species would be highly desirable
and Anti-Müllerian Hormone (AMH) is a promising candidate. This review summarizes …

Sperm are stored in the isthmic region of the oviduct under conditions that maintain viability
and suppress early capacitation steps until ovulation occurs. The initial contact between …
