The answer is 12 to 24 hours.
Fertilization is the process by which the egg and the sperm fuse to produce a zygote.
It involves a series of steps from sperm preparation: capacitation and acrosome reaction, egg and sperm fusion, cortical reaction, zygote formation, and implantation.
Ovulation is a process in which the oocytes are matured and released from the follicles. The eggs released from the follicles move through the fallopian tube if this egg is fused with sperm. The zygote gets implanted in the uterine lining.
For the proper fusion of egg and sperm, the sperm injected into the female reproductive tract must fuse with the egg within 12 to 24 hours.
