Ovulation is an essential condition for conception and a factor in whether menstruation is normal.
About 400,500 follicles mature and expel in a woman's lifetime, and only one follicle can be fully developed and discharged in each menstrual cycle, and the survival time of the egg after release < 24 hours, which shows how important it is to seize this opportunity to conceive.
Some older people who are trying to conceive need to get pregnant as soon as possible for various reasons, and ovulation monitoring is to better improve the pregnancy rate; There are also some women with abnormal menstruation who want to know the ovarian ovulation function, which can guide the menstrual problem. Commonly used methods for monitoring ovulation in clinical practice include the determination of basal body temperature, the monitoring of follicles under B-ultrasound, the determination of blood progesterone level and the detection of ovulation test strips.
Basal body temperature measurement.
Generally, ovulation occurs 14 days before menstruation, the basal body temperature is low before ovulation, and the basal body temperature will rise by 0 after ovulation3-0.5 degrees for at least 10 days and again before your next period.
The measurement method is to put a special basal thermometer under the tongue to measure the body temperature after waking up at a fixed time every morning, before getting up, not going to the toilet, not eating or drinking, and not talking. Record the basal body temperature measured every day on the abscissa of the date and the vertical axis of the body temperature, and mark the menstrual status, ** situation, medication information, etc. below **. The basal body temperature of the three-month menstrual cycle is continuously measured to observe the change of body temperature.
B-ultrasound monitoring. Follicles can be monitored by ultrasound from the 10th day of menstruation, and the diameter of the follicles can grow to 16-30 mm before ovulation, and most of them are 20-25 mm. However, dynamic monitoring of follicular development is required to determine the presence or absence of ovulation.
Progesterone test. If the menstrual cycle is regular for 28 days, blood can be drawn to check progesterone levels on the 18th and 24th days of menstruation, and then the progesterone level can be repeated 2 to 3 days later. If it is still low, it indicates anovulation. If progesterone levels are reached, ovulation is indicated.
However, for women with irregular menstruation, it is more difficult to ** the time of the next menstrual period, and it is more difficult to determine the time of progesterone measurement. And it only reflects whether the ovaries are ovulating, and it is impossible to estimate when the ovaries will ovulate.
Test strip detection. Dipstick ovulation is a test to predict ovulation by measuring the peak LH level in the urine. The blood LH peak usually occurs 36 hours before ovulation and the urine LH peak occurs within 12 hours of the blood LH peak.
Finally, it is recommended to choose the method of ovulation monitoring according to your own situation, and the probability of conception will be higher under the guidance of the doctor. I wish every woman can have healthy ovaries, and I wish every woman who is trying to conceive can be promoted to a pregnant mother as scheduled!
