  • How long after sex does fertilization occur?

  • This takes a few days. Implantation usually occurs between five and 10 days after fertilization. But as you read above, fertilization can occur as soon as a few minutes after sex or as many as five days after.

  • How long after sex implantation can you get pregnant (and why)?

  • So, the short answer to how long after sex implantation happens is anywhere from 5 鈥?15 days. After sexual intercourse, sperm can survive for up to 5 days, but an egg is only viable for about 24 hours. So, you don鈥檛 have to have sex the same day you ovulate in order to become pregnant, but there鈥檚 still a relatively tight timeline.

  • When does fertilization take place?

  • Hence, fertilization takes place in that period of time (1 day), although the sexual act itself may have occurred two or three days earlier. In the following sections we explain all the phases of this process. During the ovulation process, the egg goes from the ovary into the fallopian tubes. Sperm, meanwhile, develop continuously in the testes.

  • How long does it take for sperm to reach the egg?

  • Usually, the sperm reaches the egg within 15 to 45 minutes of ejaculation. However, the process could be much longer than that if you haven鈥檛 ovulated yet by the time you have sex, because sperm can live inside a reproductive tract and wait for an egg for up to five days.
