To get pregnant, a sperm must fertilize an egg, which typically occurs during sexual intercourse when sperm is deposited in the vagina and travels through the cervix to meet an egg released from the ovaries during ovulation. The fertilized egg then implants itself into the uterus, leading to pregnancy. Factors such as timing, reproductive health, and fertility can influence the chances of conception. For those trying to conceive, understanding the menstrual cycle and ovulation can be beneficial.
