Ovulation is a key stage in the menstrual cycle, involving the release of a mature egg triggered by luteinizing hormone around day 14, followed by transportation through the fallopian tube for potential fertilization within 12-24 hours.

Insights

Ovulation occurs around day 14 of a 28-day menstrual cycle when the ovary releases a mature egg, marking a critical phase for potential conception.
After ovulation, the egg is swiftly transported from the ovary to the uterus through the fallopian tube, where it must be fertilized within a narrow timeframe of 12-24 hours to have a chance of resulting in pregnancy.

Egg release and journey to potential pregnancy.

Ovulation is a crucial part of the menstrual cycle where the ovary releases a mature egg from a dominant follicle, triggered by a surge of luteinizing hormone around day 14 of the typical 28-day cycle.
Following ovulation, the egg is picked up by the fimbriae at the end of the fallopian tube, transported by cilia into the tube, and gently pushed towards the uterus by muscular contractions, where it must be fertilized within 12-24 hours to potentially lead to pregnancy.
