Patient's question:
NoDoctor's answer:
Hello, after sperm enters the vagina, it can survive for 2-3 days. If it encounters ovulation during this period, it can lead to conception. The lifespan of an egg is also about 2-3 days. It takes sperm about 1 day to travel from the vagina to the fallopian tubes, and the fertilized egg needs 2 days to implant.
