A sperm is the male reproductive component that fertilizes an egg. Sperm are of a surprising low quality, but additional problems can hinder reproductive efforts. The sperm may be unable to swim s...
About Sperm BankSperm bank can be defined as an establishment where the semen is stored in cold conditions for artificial insemination at a later stage. It makes use of cryopreservation freezers to fr...
Males produce hundreds of thousands to hundreds of millions of sperm within a single ejaculate depending on the species. Does it matter then which sperm is actually fertilising the egg?
(Wiley) The journal Andologia has published the first report of abnormal sperm parameters in obese men based on computer aided sperm analysis.
This year's ASRM is a big one for Cryos International, as it celebrates its 30 year anniversary, maintaining its position as the world's largest sperm bank (PRWEB) October 28, 2017 Cryos Inte...
Obesity was associated with lower sperm volume, number, concentration and motility, and higher chance of sperm defects, according to findings published in Andrologia.“Previous studies on obesity and...
Learn how long sperm cells are able to survive in a variety of environments outside the body, along with information about sperm health and fertility.
Sperm count in men from North America, Europe, Australia and New Zealand declined by 50-60 percent between 1973 and 2011, according to a new study from the Hebrew University of Jerusalem. Surprisingly...
The size and shape of individual sperm, known as sperm morphology, is a contributing factor to fertility. Learn how it is tested and what the results mean.
The efficiency of intracytoplasmic sperm injection (ICSI) in bovines is low compared to other species due in part to inadequate egg activation and sperm nucleus decondensation after injection. We hypo...
Varicocele disease is well-known cause of infertility in men. The presence of spermatic varices veins create a hostile environment to spermatogenesis. It results in reduced quality of the sperm produc...
The cryoprotective agent (CPA) is one of the most important factors that affects the cryosurvival of sperm. The aim of the present study was to compare two different CPAs, glycerol (Gly) and ethylene ...
Sperm-egg interaction depolarizes the egg membrane, allowing the sperm to enter; however, if the egg membrane is not allowed to depolarize from its resting potential (e.g. by voltage-clamp), the sperm...
To diagnose infertility in men, semen analysis is conducted in which sperm morphology is one of the factors that are evaluated. Since manual assessment of sperm morphology is time-consuming and subjec...
