How to determine the woman’s ovulation period?

How to determine the woman’s ovulation period? Every woman has her own specific ovulation period. Even women with irregular menstruation have their own ovulation period. Just remember that the first day of menstrual cramps can calculate the ovulation period, and at the time of ovulation, some women Physiological reactions can be manifested, or it can be detected by some instruments. The mechanism of basal body temperature changes: The body temperature regulation center is extremely sensitive to the action of progesterone (also known as progesterone), and a certain amount of progesterone (12,8nmol/L) can cause an increase in body temperature. The next day after ovulation, the corpus luteum is formed by the ovary. The secretion of progesterone from the corpus luteum will increase the body temperature by about 0.6 degrees Celsius, and the body temperature will be high and low. The high temperature period lasts about 12-16 days (average 14 days). If there is no pregnancy, the corpus luteum atrophy stops the secretion of progesterone, the body temperature drops, return to the basic line, menstrual cramps. If it is pregnant, because the corpus luteum is supported by hormones secreted by the embryo, it continues to secrete progesterone, and the body temperature continues to be high. If the ovary is dysfunctional, there is no ovulation and no corpus luteum formation, so the body temperature will continue to be low. The menstrual cycle of women begins with the first day of menstruation. The length of the cycle varies from person to person, ranging from 21 to 35 days, with an average of about 28 days, which is separated by ovulation day and follicular phase before ovulation. After ovulation, it is the luteal phase. The length of the follicular phase is not necessarily the same, but the normal luteal phase is fixed at about 14 days for up to two days. The role of basal body temperature 1. Determine whether ovulation guides contraception. The general basal body temperature of follicular phase is 36.5 °C, and the luteal phase rises above 0.5 °C. Therefore, biphasic performance appears, indicating ovulation. If the single-phase type has no late-increased body temperature curve, suggest No ovulation. If the body temperature increases by 0.3 to 0.6 ° C or even higher within 24 hours, it means that it is in the state of ovulation. In addition, the basal body temperature can also roughly see the quality of the discharged eggs. If the basal body temperature is high and the temperature can last for 13 to 14 days, then the egg quality is good. 2, diagnosis of early pregnancy and judgment of early pregnancy safety If the basal body temperature is higher for more than two weeks, it is necessary to consider going to the hospital for examination, because you may be pregnant. If ≥ 20 days can be determined as early pregnancy. In the early pregnancy, the BBT curve gradually decreased, indicating that the luteal function is insufficient or the placenta is dysfunctional, and there is a tendency to miscarriage. 3, observe the corpus luteum function BBT should rise immediately after ovulation, and continue at a high level ≥ 11 days. If the BBT rises in a stepped shape, the curve will take a high level after 3 days or the BBT will rise steadily. On the 11th, it can be diagnosed as luteal function. 4, suggest that other lesions during the menstrual period BBT does not decrease, there may be endometriosis or early subclinical abortion, endometriosis lesions will produce absorption of heat after bleeding. When the BBT of the primary amenorrhea is biphasic, uterine amenorrhea should be considered, such as congenital absence of uterus or genital tuberculosis to destroy the endometrium. 5, the calculation of appropriate endometrial biopsy irregular time period patients, to understand the endometrial secretion and luteal function, should be estimated after the BBT rise next 2 to 3 days before the menstrual cramps for endometrial biopsy. The ovulation date of a woman is generally about 14 days before the next menstrual cramp. After the egg is discharged from the ovary, it can survive for 1-2 days in the fallopian tube to wait for fertilization. The sperm of the man can maintain 2-3 days of fertilization ability in the woman’s reproductive tract. Sex life is the easiest in the days before and after the egg is discharged. Pregnancy, if you do not want to get pregnant, you must do contraception.
