Sperm cells exhibit extraordinary phenotypic variation, both among taxa and within individual species, yet our understanding of the adaptive value of sperm trait variation across multiple contexts is incomplete.

Background and Aims: Embryo aneuploidy is caused by many factors, including patient age, sperm quality and sperm selection method. There are several methods for selecting sperm, ICSI (intracytoplasmic sperm injection) and IMSI (intracytoplasmic ...

No evidence for pre-copulatory sexual selection on sperm length in a passerine bird. [PDF]
There is growing evidence that post-copulatory sexual selection, mediated by sperm competition, influences the evolution of sperm phenotypes. Evidence for pre-copulatory sexual selection effects on sperm traits, on the other hand, is rather scarce.

The birth of a healthy child in a married couple with a history of multiple unsuccessful attempts at ART by selecting sperm on oocyte-cumulus complexes. Case report [PDF]
In male infertility, couples must use assisted reproductive technologies with the intracytoplasmic sperm injection (ICSI) technique. A significant disadvantage of ICSI is bypassing natural selection barriers since selective processes in the female ...

Novel distance-progesterone-combined selection approach improves human sperm quality
Background Sperm selection is essential for the health of offspring conceived via assistive reproductive technology (ART). Various methods of sperm preparation for in vitro fertilization and intracytoplasmic sperm injection have been developed to acquire

Rheotaxis-based sperm separation using a biomimicry microfluidic device
Sperm selection is crucial to assisted reproduction, influencing the success rate of the treatment cycle and offspring health. However, in the current clinical sperm selection practices, bypassing almost all the natural selection barriers is a major ...

Conventional Magnification Suffices for High-quality Sperm Selection When Embryologist Experience Is Optimized: A Comparison with MSOME [PDF]
The ability to choose the appropriate sperm is essential to enhance the assisted reproductive technologies results. This study evaluated the performance of five embryologists in selecting sperm using conventional magnifications.
