Sexual intercourse frequency and conception have what relation?

Woman normal menstruation, menstrual cycle is 28 days or so commonly, period is commonly 3 ~ 7 days, HP is moderate, colour is normal. Equivalent to the middle of the menstrual cycle is oviposit period. Ovulation often vaginal spurt, sexy, namely "LeYuZhi". After eggs leave the ovaries, life in general is 1 ~ 2 days. Sperm in the vagina acidic environment can survive up to 8 hours,



Can survive into the uterus after 2 ~ 3 days. So each menstrual cycle within 2 days before and after ovulation, sexual intercourse becomes pregnant easily. Sexual intercourse if too thin, is easy to lose time conception. In general, sexual life in 1 ~ 2 times per week, for moderate, women's ovulation can be appropriately increased.



Some couples, when they want to pregnancy, is always hard to frequent intercourse, backfired. If ejaculation sex or not 1 times a day, it can reduce the amount of semen and sperm density decreased, a significant reduction in the rate and survival rate of sperm activity, sperm in female reproductive tract ability to travel and meet with egg "power", less chance of natural conception is greatly reduced.



Sexual intercourse frequency would lead to another cause of infertility is likely to cause her immune infertility. This is because the wife frequently repeated contact with husband's sperm, sperm, for some women can generate specific immune response to say, the sperm and semen is a kind of antigen material, easy to stimulate the body to produce antisperm antibodies. The more the more frequently the sexual intercourse, the woman to absorb the man's sperm, antigen stimulate antibody level is more intense. These antibodies basically has two kinds: one kind is called "agglutinating antibody, called a" brake antibodies. When sperm meets the agglutinating antibody, accumulation will stick together and bound to each other and lose the ability of activity, the last is absorbed by the female genital tract mucosa. Sperm if you encounter "brake antibodies," will make the action, and the antibody "brake" still can make the contraction of the uterus and fallopian tube ability is abate, obstacles to move to the uterine cavity fertilized egg. Frequency of sexual intercourse, therefore, infertile couples, and the best suspended for a period of sexual life, or the use of condoms 3 ~ 6 months, to facilitate conception
