Answer from Roger W. Harms, M.D. (With Mayo Clinic obstetrician and medical editor-in-chief )
The life span of sperm after ejaculation depends on the environmental conditions.
Sperm ejaculated outside the body may survive only minutes to a few hours.
Sperm ejaculated into a woman’s vagina can live in a woman’s reproductive tract for up to five days or perhaps even longer. Fertilization is possible as long as the sperm remain alive.
Salute e …peggio nun nisse.
