NEET BIOLOGY

Detailed explanation-1: -The maturation of eggs typically takes about 14 days and can be divided into 2 distinct periods. During the initial period, many eggs, as many as 1000, begin to develop and mature. The second phase of development requires gonadal hormone stimulation to stimulate further development.

Detailed explanation-2: -Most girls begin menstruating between nine and 13 years of age, but their ovaries don’t start releasing eggs until a least a year or two later. Simple mathematics would suggest a woman’s egg supply would then typically exhaust itself around 33 years later.

Detailed explanation-3: -During a menstrual cycle, hormones cause some follicles to grow and mature an egg within. Luteinizing hormone (LH) is a follicle-stimulating hormone that signals the ovary to release one egg, the most healthy one. When LH surges, the mature egg is released from the follicle.

Detailed explanation-4: -During your period, follicles (pockets) in your ovaries are stimulated to grow-there’s 1 egg in each of these follicles. During the week or so after your period ends, 1 of the eggs becomes totally mature each month. When an egg is mature, it means it’s ready to be fertilized by a sperm cell.

Detailed explanation-5: -When a young person reaches puberty, they begin to ovulate-a process in which a mature egg cell (also called an ovum) that is ready for fertilization by a sperm cell is released from one of the ovaries (two reproductive organs located in the pelvis).
