Detailed explanation-1: -Ovulation always occurs 14 days before menses; therefore, with an average 28-day cycle, ovulation occurs on day 14. At the end of the proliferative phase, 17-beta-estradiol levels are at a high due to the follicle maturation and increased production of the hormone.

Detailed explanation-2: -During days 10 to 14 of the cycle, only one of the developing follicles forms a fully mature egg. Around day 14 in the menstrual cycle, a sudden surge in LH causes the ovary to release this egg. This is ovulation. After ovulation, the hormone progesterone rises which helps prepare your uterus for pregnancy.

Detailed explanation-3: -In an average 28-day menstrual cycle, ovulation typically occurs about 14 days before the start of the next menstrual period. However, each person’s cycle length may be different, and the time between ovulation and the start of the next menstrual period may vary.

Detailed explanation-4: -Around Day 14 (in a 28-day cycle), hormones cause the mature follicle to burst and release an egg from the ovary, a process called ovulation. Over the next few days, the egg travels down the fallopian tube towards the uterus.

Detailed explanation-5: -Follicular Phase (Day 1-14) This phase is when the uterine lining thickens in preparation for a fertilized egg to be implanted, leading to pregnancy. During this phase, the ovaries ready the egg to be released into the uterus on day 14 (the day of ovulation) by increasing reproductive hormone production.
