Sperm aneuploidies and low progressive motility.
BACKGROUND Patients with poor semen quality show increased sperm disomy and diploidy rates. Oligozoospermia and teratozoospermia are known to influence sperm aneuploidy, but there is still a debate about whether aneuploidies are associated with reduced motility. METHODS Ejaculates from a large group of patients were examined by light microscopy to evaluate sperm concentration, motility and mo...
متن کاملHuman Male Meiosis and Sperm Aneuploidies
Reports indicate that infertile males, especially those with low sperm count, have an increase in chromosomally-abnormal spermatozoa, therefore the study of these individuals is critical for the field of assisted reproduction. Importantly, aneuploid sperm remain able to fertilize eggs, often resulting in repetitive intracytoplasmic sperm injection (ICSI) failure, recurrent miscarriage, and offs...
متن کاملLong-term cryostorage of sperm in a human sperm bank does not damage progressive motility concentration.
BACKGROUND The use of quarantined cryopreserved semen is mandatory in donor insemination programs. Whether sperm cells can survive and retain their ability to fertilize after long-term storage remains a controversial issue. The objective of this study was to determine the effect of the duration of cryostorage in liquid nitrogen on the sperm cells' progressive motility concentration (PMC) in a l...
متن کاملSperm motility and MSP.
Form follows function, and this maxim is particularly true for the nematode sperm cell. Motility is essential for fertilization, and the process of spermatogenesis culminates in the production of a crawling spermatozoon with an extended pseudopod. However, the morphological similarity to amoeboid cells of other organisms is not conserved at the molecular level. Instead of utilizing the actin cy...
