Pregnancy requires both men and women to have healthy reproductive function, and during a woman’s ovulation period, a man’s ejaculation into the woman’s vagina can increase the chances of pregnancy.
Female ovarian ovulation is usually about 14 days before the next menstrual period, and 4 to 5 days before and after ovulation is the fertile period. At this time, the male ejaculate into the vagina, sperm movement through the vagina, the uterine cavity to reach the fallopian tube, and the fallopian umbrella picked up by the fallopian tube into the fallopian tube of the egg to meet, sperm and egg combination occurs. Six to seven days after fertilization, the embryo is deposited in the uterine lining and grows.
In summary, the process of pregnancy is the result of the matching of reproductive functions of both men and women, and is closely related to the maturity of the female follicle, normal ovulation, tubal patency, sperm viability and other factors.
Infertility may result if the woman fails to ovulate normally, chronic pelvic inflammation leads to tubal adhesion, etc., or if the man fails to produce enough, healthy sperm, or cannot ejaculate normally. When a couple has been having normal intercourse for a year and fails to conceive without contraception, it is called infertility and the couple should consult a doctor together to find the cause.
