When is a woman least fertile? refers to the period in a woman’s menstrual cycle when the chances of conceiving are lowest. This typically occurs during the follicular phase, which begins on the first day of menstruation and ends when ovulation occurs, usually around day 14 of a 28-day cycle.
Understanding a woman’s fertile period is crucial for both contraception and conception. Avoiding unprotected intercourse during this time can help prevent pregnancy, while couples trying to conceive may wish to time intercourse to increase their chances of success.
