- 摘要:
- Standardized swim-up trials are used in IVF clinics to select particularly motile spermatozoa in order to increase the probability of a successful

- 摘要:
- for population persistence. For males, fertility relies on the ability of sperm to collide and fuse with eggs; consequently, sperm morphology is predicted to be a prime target
