The composition of semen varies, but sperm as a general rule make up only a very small percentage, usually less than five percent, of the volume. The groundwork for the production of these unique cells is laid during fetal development. Specialized cells known as germ cells migrate to the ...
checking for cell viability once the eggs are produced is a process called oocyte (immature egg) selection. This is done prior to fertilization to choose the eggs that have the best chance of leading to pregnancy. The sperm cells are also analyzed via "sperm washing," which removes inactive ...

Oligospermia is a possible cause of male infertility that can be mild, moderate or severe depending on the concentration of sperm in the ejaculate. This seminal alteration can have various causes and hinders natural pregnancy, so it may be necessary to o
