Typical range: 21-35 days
Ovulation Day = Cycle Length - Luteal Phase
The fertile window extends from 5 days before to 1 day after ovulation, as sperm can survive up to 5 days in the reproductive tract.
Ovulation is the release of an egg from one of the ovaries, which typically occurs once per menstrual cycle. This event is crucial for conception, as the released egg can be fertilized by sperm for about 12-24 hours after ovulation. Understanding your ovulation timing can help with family planning, whether you're trying to conceive or avoid pregnancy.
The fertile window spans approximately 6 days: the 5 days before ovulation and the day of ovulation itself. This is because sperm can survive in the female reproductive tract for up to 5 days, waiting for an egg to be released. Having intercourse during this window maximizes the chances of conception.
