The severity of sperm alterations in the different etiologic categories was evaluated by the total motile sperm count per ejaculate (TMS) (normal > 16). The TMS was less than 5 in classical causes of male infertility such as testicular failure, endocrinopathy, cancer, or antisperm antibodies. ...
If a male's left vas deference is blocked, how is his sperm count affected? Explain. Under what circumstances is population growth represented by G=rN Why is it more likely for a woman to get pregnant if intercourse occurs a couple of days before ovulation?
In addition, SP-TAC was measured in three different ejaculate portions from 43 ejaculates (one ejaculate per boar): the sperm-peak portion (first 10 mL) of sperm rich fraction (SRF); the rest of the SRF; and the post-SRF. Experiment 2. Relationship between SP-TAC and sperm quality ...
The purpose of this study was to quantitate changes in seminal volume, sperm count, motility, qualitative forward progression, and total motile sperm cells per ejaculate, across three consecutive ejaculates collected from individuals within 24 h preceding an IVF cycle.Said, Al-HasenReed, Michael L...

An aliquot (200渭l) from each ejaculate was used for evaluation of semen characteristics (wave motion, motility, viability, sperm morphology, intact-acrosome, sperm concentration, total sperm count per ejaculate). The remaining volume was centrifuged to collect SP and TPC (g/dl) of SP was ...
We report here the case of two brothers, both exhibiting a total absence of motile and normal spermatozoa in their ejaculates, with a very high index of multiple abnormalities (IMA) per sperm cell. Two ICSI attempts were made for one of these brothers, which were both unsuccessful....
