Best time to conceive: scientific planning to improve success rate

The best time for conception mainly revolves around the ovulation period of women. It can be divided into three levels based on physiological laws, living habits and medical advice:core period(1-2 days before ovulation),secondary period(3-5 days before and after ovulation) andInfluencing factors(such as age, health status).The ovulation period is the stage with the highest probability of pregnancy, and accurate measurement of ovulation day can be achieved through basal body temperature method, ovulation test strips or ultrasound monitoring.In addition, avoiding tobacco and alcohol, eating a balanced diet and exercising moderately can also optimize conditions for conception.

Scientific calculation of ovulation period

Women's menstrual cycle is usually 28 days, and ovulation is usually about 14 days before the next menstruation.For example, if the cycle is 30 days, ovulation will be around day 16.At this time, the cervical mucus becomes transparent and elastic, and the basal body temperature rises by 0.3-0.5°C, both of which are signals of ovulation.Ovulation test stripsPredicting ovulation by detecting the peak value of luteinizing hormone (LH) in urine can achieve an accuracy of more than 90%.It is clinically recommended to monitor follicular development in combination with B-ultrasound, especially for those with irregular cycles.

Optimize the frequency and timing of sex

The pregnancy rate is highest in intercourse 1-2 days before ovulation, because sperm can survive in a woman's body for 2-3 days, while eggs only last 12-24 hours.It is recommended to have intercourse every other day during the ovulation period to avoid frequent ejaculation and lower sperm quality.The American Society for Reproductive Medicine points out that the monthly probability of natural pregnancy for healthy couples aged 20-35 is about 20%-30%, which can be increased to 30%-40% with reasonable planning.avoid misunderstandingsFor example, "abstinence to save sperm" may lead to an increase in aging sperm.

Lifestyle Habits and Assistive Means

Men should avoid hot environments (such as saunas), smoking and excessive alcohol consumption, which can reduce sperm count.Women can supplementfolic acid(400μg/day) to prevent fetal neural tube defects.Clinical data shows that women with a BMI of 18.5-24.9 have a higher pregnancy rate.Some couples will use fertility monitors (such as "Clearblue" ovulation tester) or APPs (such as "Flo"), but individual differences should be noted.

Summary and comprehensive suggestions
