Patient's question:
Patient Gender: Why is she not pregnant? Onset Time: Test Results:Doctor's answer:
Pregnancy requires certain prerequisites to be met. As long as the conditions are sufficient, the probability of conception during intercourse in the ovulation period is high. The conditions for fertility can generally be divided into the following aspects:(1) The male testes must be able to produce normal sperm. A normal adult male releases 2–6 milliliters of semen per ejaculation, with the sperm count per milliliter exceeding 60 million, and more than 60% of the sperm being motile. Abnormal sperm should account for less than 15%–20%. If the sperm do not meet the above standards, it will be difficult for the female to conceive.
(2) The female ovaries must be able to release healthy, mature eggs. Women with normal menstruation have one healthy, mature egg released each menstrual cycle, which is necessary for the possibility of pregnancy. For women with impaired ovarian function or irregular menstruation, it will be difficult to conceive.
(3) Normal sexual activity must occur around the female ovulation period to give sperm and eggs a chance to meet and fertilize. Sperm can survive in the female reproductive tract for 1–3 days, while eggs can survive for about 1 day after being released. The ovulation time is approximately 14 days before the next menstrual period. Intercourse within a few days before and after ovulation is the only time when pregnancy is possible. Intercourse outside the ovulation period will not result in pregnancy.
(4) The reproductive tract must be unobstructed. The male’s spermatic ducts must be unobstructed for sperm to be expelled. The female’s reproductive tract must also be unobstructed, allowing sperm to reach the fallopian tubes and meet the egg without hindrance during intercourse. The fertilized egg can also smoothly enter the uterine cavity.
(5) The uterine environment must be suitable for the fertilized egg to implant and develop. After fertilization, the egg develops while moving toward the uterus. It reaches the uterine cavity after 3–4 days and burrows into the nutrient-rich endometrium around 6–8 days, where it continues to develop into a fetus. The development of the fertilized egg and the growth of the endometrium are synchronized. If the fertilized egg enters the uterine cavity prematurely or is delayed, the endometrium will not be suitable for implantation and further development, making pregnancy impossible.
All the above prerequisites for conception are essential. Otherwise, infertility may occur.
6. Under normal physiological conditions, if a couple lives together without taking contraceptive measures, the chance of pregnancy each month is 20%, after six months it is 70%, and after one year it is 80%. If the couple remains childless after more than one year without taking contraceptive measures, medical examination should be conducted. In other words, even if a couple has no fertility issues, it does not guarantee that they will conceive every month they try.
