In general, only one follicle on one side of the ovary is mature and discharged, and its fertilization ability can be maintained for about half a day. Although the number of male sperm is high and can survive 1-2 days in a woman’s body, not many sperm really reach the fallopian tube, and only one sperm can successfully combine with the egg in the end. all efforts to miss the day of ovulation will be meaningless! There are some infertile couples who do not have any diseases affecting fertility, but because they do not have a good understanding of the basic knowledge of ovulation, which leads to many years of infertility, women with regular menstruation generally have a cycle of about 28 days, and their ovulation is in the middle of the menstrual cycle, so how to correctly grasp the best time to conceive has become a common concern for many couples of childbearing age. How to accurately grasp the ovulation period of women! 1. Changes in cervical mucus: During ovulation, women will experience changes in vaginal secretions. The cervical mucus, which used to be sticky and turbid, will become thin and transparent, and the amount will increase because the female reproductive tract has changed to meet the sperm, and the above changes will enable the sperm to penetrate the cervical mucus more smoothly and reach the fallopian tubes. 2. Changes in basal body temperature: Women of childbearing age will experience changes in basal body temperature during ovulation, so the arrival of ovulation can be initially determined by monitoring the basal body temperature, which is a convenient and economical way to determine the basal body temperature and can be done at home at any time. However, the method also has shortcomings, the basal body temperature is easily affected by weather, season, activities, emotions, etc., and the change of basal body temperature is often about half a degree, so there are certain limitations. 3, changes in female physiology: women during ovulation have a higher desire for sexual intercourse than usual, individual women will be more intense, while some women can have a slight pain in the lower abdomen, breast heaviness, etc., male compatriots can carefully observe the physiological changes in their wives, so as to improve the probability of conception. 4, medical aid judgment: for couples who have not been pregnant for a long time or have difficulty conceiving, it is recommended that dynamic examination of urinary hormone levels and ultrasound monitoring of ovulation can be taken to the hospital, and the above methods can more accurately determine the development of follicles and emissions, thus improving the probability of conception.
