In the male clinic, there are often young couples who come to see me. Often the first thing they say to me is, “Doctor, I suspect I’m infertile! I’ve been trying to conceive for two months and I haven’t won yet!” I can only tell him in a scientific manner, “There are data showing that a normal man and woman have about a 60% chance of pregnancy in a year. (The male semen quality is fine, the female ovulation is fine, and regular sexual intercourse.)” Without waiting for me to finish, I was greeted by the inquisitive eyes of the young couple: “Doctor, what can be done to increase the chance of conception?” Timing of conception and frequency of sex If we say that the usual menstruation is regular, we usually have no problem by default, in this case, sex every 2-3 days. The ovulation date of a woman is usually about 14 days before the next menstrual period. The egg can survive 1-2 days in the fallopian tube after being discharged from the ovary to wait for fertilization; the man’s sperm can maintain the fertilization ability in the woman’s reproductive tract for 2-3 days. Give yourself patience for 12 months and 80% of couples can succeed. If the woman is over 35 years of age when preparing for pregnancy, try to conceive for 6 months. There is a certain pattern to everything, give your tadpole a little more time and patience. If it is not successful come back to the hospital. If you normally have irregular periods, then: monitoring follicles is optional and without special circumstances, you can use basal body temperature (normal daily temperature before waking up in the early morning (i.e. basal body temperature) is below 37 degrees, around 36.4 – 36.6 degrees. The body temperature drops slightly during ovulation and rises on average by about 0.5 degrees after ovulation, maintaining it until just before the onset of menstruation when it starts to drop) and ovulation test strips. These two methods are relatively simple and can be operated at home by yourself, and the accuracy is also okay, with an error of about 2-3 days. The more accurate method is ultrasound follicle monitoring, which is especially suitable for women with irregular menstruation, starting on the 11th-12th day of menstruation, going to the hospital for ultrasound to see the follicles, and then continuing to monitor at intervals according to the follicles detected until you see the follicles expel. (It is relatively troublesome and may require several trips back and forth to the hospital.) If no follicles are detected on ultrasound for 2 months in a row, you are not ovulating and need to be seen by a gynecologist for systematic treatment. The body can also give some hints before and after ovulation, the female body’s endocrine hormones will change, if you are careful, can be detected. For example, before and after ovulation, there may be breast tenderness, vague pain in one side of the abdomen, a little vaginal bleeding, increased mucus discharge and straining, etc. The most important thing to remember is that you can’t be too careful. The most important role of the snapping process is to let the male sperm into the woman’s body, and as for how the position does not have much impact on the outcome (emphasis on one thing: premature ejaculation and circumcision are not affected by pregnancy, but if impotence can not enter the guide is affected). So it is not necessary to talk about too many positions when having sex, and do not give yourself and your partner too much psychological pressure to force the use of fixed positions that are not suitable for both sides, not only will affect the harmony of the couple’s sexual life, the formation of a strange circle of couples in order to have sex, and most importantly, unpleasant sex, will affect the male sperm secretion and ejaculation process, so that the epididymis can not fill the secretion of sperm, ejaculation is not sufficient, so that sperm The number of sperm is greatly reduced, low level of play. For many friends care about the same room after the inversion of this thing is not necessary, in general after the same room lying still for a while on the good, if not assured in the buttocks under a pillow, and inversion is not necessary to do. Life and living Unhealthy habits should be changed: It is best for men to quit smoking during pregnancy preparation, especially second-hand smoke, which is more harmful. The best thing to do is to stop smoking, especially second-hand smoke, which is more harmful. Also, stay away from hot baths, saunas, chemical and radiological sites to take good care of your tadpoles. Moderate physical exercise: such as swimming, jogging, ball games, etc., to enhance physical fitness. (2-3 times a week, a half hour to an hour can be.)
