A woman's egg lives in the uterus for 12 to 24 hours after ovulation. This short time period makes it critical to understand ovulation to increase chances of pregnancy.
Understanding fertility helps increase a woman's chances of getting pregnant. Based on egg ovulation and sperm life, intercourse should occur a few days preceding, and on the day of, ovulation.
Sperm survive in the uterus between 3 to 5 days, depending on strength. Having intercourse 2 days before ovulation gives slower sperm enough time to reach the uterus and meet the egg as it descends down the Fallopian tube.
The easiest way to determine ovulation is to check cervical mucus consistency. Five days before ovulation, cervical mucus is thin, clear, stretchy and slippery, creating a fertile environment that speeds a sperm's journey to the egg.
