Motility7
- If sperm count, motility, structure are abnormal then other analyses (hormonal, genetic) are made. (drseymur.az)
- In semen analysis, absence of sperm is called - azoospermia, low concentration- oligospermia, low motility - astenospermia, abnormal sperm morphology - teratospermia. (drseymur.az)
- In our study, we conducted a thorough analysis and unveiled a multitude of abnormalities in zebrafish sperm and testicular tissue caused by ZPT exposure, including a dose-dependent diminishing of testosterone levels, various sperm deformities, decreased sperm concentration and motility, and ROS-induced testicular tissue DNA damage. (bvsalud.org)
- Exposure to PM2.5 was associated with alterations in D-Aspartate levels, which might partially mediate the association between PM2.5 and reduced sperm motility. (bvsalud.org)
- Moreover, urinary TCAA modeled as a continuous variable was negatively associated with sperm progressive motility and total motility, while the inverse associations across increasing urinary TCAA quartiles were seen among leaner men (BMI (bvsalud.org)
- Exposure to DBPs reflected by urinary DCAA and TCAA was inversely associated with sperm motility and such effects were more evident among leaner men. (bvsalud.org)
- Moreover, the distinction between living round spermatids, to be used in ROSI, and dead round spermatids, to be discarded, needs specific methods and skills, not required in the case of ICSI where sperm cell viability can be easily evaluated on the basis of sperm motility in most cases. (wikipedia.org)
ICSI4
- On the other hand, when the sperm is mechanically inserted into the ovum via ICSI, it is not clear precisely when the ovum and the sperm unite and cease to be, or at least, it is not clear to us - and we have not taken a position on the question. (robertpgeorge.com)
- In terms of insemination, ICSI needs only one sperm cell per oocyte , while IVF needs 50,000-100,000. (wikipedia.org)
- [2] The microinjection procedure for ROSI also differs slightly from that of ICSI, since additional stimuli are needed to ensure proper oocyte activation after spermatid injection. (wikipedia.org)
- In ICSI Treatment IVF Treatment, the male partner provides a sperm sample in case of a very low count. (sisuhospital.com)

- Count, mobility, morphology (structure) of sperms are the most important indicators in semen analysis. (drseymur.az)
Embryo2

- Round spermatid injection (ROSI) is a technique of assisted reproduction whereby a round spermatid is injected into oocyte cytoplasm in order to achieve fertilization. (wikipedia.org)
