At coitus, human sperm are deposited into the anterior vagina, where, to avoid vaginal acid
and immune responses, they quickly contact cervical mucus and enter the cervix. Cervical …

The identification of human sperm hyperactivated motility has potential importance in sperm
function tests, as well as in quality control assays and in reproductive toxicology …

Sperm transport and motility were studied through the transparent walls of the mouse
oviduct by direct microscopic observation and videomicrography. Observations were made …

Sperm acrosome reaction: its site and role in fertilization† Page 1 Biology of Reproduction,
2018, 99(1), 127–133 doi:10.1093/biolre/ioy045 Review Advance Access Publication Date: 16 …

Sperm from naturally mated mice were observed and videotaped moving within mouse
oviducts. The typical pattern of sperm progress involved intermittently breaking free and …

A movement pattern known as hyperactivation has been observed among sperm recovered
from the periovulatory oviduct of several species. In culture medium, hyperactivated sperm …

Fertilization is the process by which haploid gametes, sperm and egg, unite to produce a
genetically distinct individual. Interest in this area has exploded in recent years. Here are …

These experiments were conducted to determine whether or not sperm motility
hyperactivation facilitates penetration of the zona pellucida of the oocyte. Two approaches …

Hyperactivated motility, a swimming pattern displayed by mammalian sperm in the oviduct
around the time of ovulation, is essential to fertilization. Ca2+ has been shown to be crucial …

Spermiogenesis refers to the process by which postmeiotic spermatids differentiate into
elongated spermatids and eventually spermatozoa. During spermiogenesis, round …
