Machine learning for sperm selection

Nature Reviews Urology, 2021
Infertility rates and the number of couples seeking fertility care have increased worldwide over the past few decades. Over 2.5 million cycles of assisted reproductive technologies are being performed globally every year, but the success rate has remained at ~33%.

Sperm Selection Technology in ART

Seminars in Reproductive Medicine, 2021
AbstractIntracytoplasmic sperm injection (ICSI) is a commonly used in vitro fertilization technique. Selection of sperm for injection is currently done using subjective assessment of morphology, which may not accurately identify the best-quality sperm.

Sperm competition games: sperm selection by females

Journal of Theoretical Biology, 2003
We analyse a co-evolutionary sexual conflict game, in which males compete for fertilizations (sperm competition) and females operate sperm selection against unfavourable ejaculates (cryptic female choice). For simplicity, each female mates with two males per reproductive event, and the competing ejaculates are of two types, favourable (having high ...

Sperm Selection: Effect on Sperm DNA Quality

2013
The selection of spermatozoa without DNA fragmentation and chromosomal diseases prior to assisted reproductive techniques helps to optimize the outcome of the treatment; in particular, sperm selection prior to in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is crucial.

Microfluidic Sperm Selection

2020
With advances in assisted reproduction techniques, the degree of demand on the male gamete has decreased to such a level that the role of the sperm has been reduced to a mere packet of DNA to be released into the cytoplasm of the oocyte. Now, we know that regardless of appearance, this package may contain unpleasant surprises such as sperm DNA damage ...

Sperm longevity following pre-freeze sperm selection

Journal of Equine Veterinary Science, 2012
centrifugation improves cryosurvival after delayed cryopreservation, as compared to the standard centrifugation processing. Moreover, centrifugation processing directly after semen collection and storage of selected sperm was compared with centrifugation of stored sperm just prior to cryopreservation.
