Answer:
During ovulation, which typically occurs in the middle of a woman's menstrual cycle, the ovaries release a mature egg, or ovum, into the fallopian tubes. This process is triggered by a surge in luteinizing hormone (LH) from the pituitary gland. The surge of LH causes the dominant follicle in one of the ovaries to rupture, releasing the egg. The egg then travels down the fallopian tube towards the uterus. This is the time when a woman is most fertile and has the highest chance of conceiving if sperm is present. The lining of the uterus thickens in preparation for potential implantation of a fertilized egg. If the egg is not fertilized within 12 to 24 hours after ovulation, it will disintegrate, and the menstrual cycle will continue. However, if fertilization occurs, the fertilized egg will implant into the uterine lining, leading to pregnancy. Ovulation is a crucial process in the reproductive cycle and plays a central role in fertility.
