Sperm and egg during ovulation

A woman's menstrual cycle usually ranges from the 1st to the 10th of each month. During this period, the woman's ovaries release eggs, and sperm move from the fallopian tubes to the ovaries to prepare for fertilization with the eggs. This process takes several days, depending on the woman's menstrual cycle and the sperm's survival time.

During a woman's ovulation period, the ovary will release a mature egg, which is about 0.4mm in size. Sperm usually survives in a woman's body for 3-4 days, but some sperm can survive longer. When the sperm meets the egg, they combine through hydrogen bonds to form a fertilized egg. This fertilized egg will implant in the woman's uterus and begin a new journey of life.

A woman's ovulation period can be determined by measuring her basal body temperature and observing changes in her abdomen. Basal body temperature refers to the phenomenon that the body temperature rises by 0.3-0.5 degrees Celsius when the human body is not performing any activities. During a woman's ovulation period, her basal body temperature will rise and last for several days. In addition, women can also determine their ovulation period by observing changes in their abdomen. Generally speaking, the abdomen will begin to enlarge slightly and the sex drive will increase.
