If a couple has not used contraception and remains childless after two years of marriage, infertility can be diagnosed. The cause may lie with the male partner, the female partner, or both. Many childless couples attempt to increase conception chances by having more frequent intercourse. However, this behavior itself can actually contribute to male infertility.
Survey data indicates that 70% of men engage in excessive sexual activity, particularly newlyweds. Some couples even maintain high-frequency intercourse during infertility treatment, mistakenly believing more sex increases the wife's chances of conception. In reality, excessive sexual activity can cause male infertility. Due to the eagerness to have a child, many overlook this critical factor.
Typically, a healthy male ejaculates 1–6 milliliters of semen during intercourse, containing over 50 million sperm. While 70% of these sperm exhibit normal motility, only 1%–5% reach the uterine cavity. Ultimately, just one sperm fertilizes the egg to form a zygote. This highlights the extremely high attrition rate of sperm.
Excessive sexual activity diminishes both sperm quality and quantity, reducing the chances of conception.
If a couple engages in excessive intercourse, sperm supply cannot meet demand, and poor quality further impairs fertilization. Moreover, as an antigenic substance, frequent exposure to sperm can cause women to continuously produce anti-sperm antibodies. These antibodies may cause sperm agglutination or loss of motility, directly hindering fertilization. Thus, excessive sexual activity often backfires.
Experts recommend a frequency of 2-3 times per week.Simultaneously, both partners should undergo timely fertility assessments. Women should check for fallopian tube patency, egg maturity, ovulation capability, and uterine suitability for fetal growth. Men should evaluate sperm quality and screen for immune antibodies in either partner. Identifying infertility causes early enables targeted treatment without missing the optimal window.
Cases of male infertility caused by excessive sexual activity are common. It's crucial to understand that more frequent intercourse does not necessarily increase the chances of conception. A balanced approach to sexual activity enhances fertility, and maintaining overall health further improves reproductive outcomes. Additionally, several other factors can contribute to infertility and require attention.
What causes male infertility?
Fertility involves several key steps: First, the testes must produce sufficient quantities of normal, healthy sperm. Second, sperm must undergo further maturation and selection within the epididymis. Third, sperm must be transported through the reproductive tract for ejaculation. Fourth, the seminal fluid and associated reproductive glands must function normally.Fifth, these sperm must be deposited into the female reproductive tract through normal sexual function and intercourse.
Furthermore, both partners must not have immune dysfunction or abnormalities. Issues in any of these reproductive processes can lead to male infertility. For example, if the testes fail to produce sperm, infertility occurs at the source.Other factors include: - Testicles failing to produce sperm - Sperm failing to mature in the epididymis - Obstructed sperm ducts preventing sperm passage - Problems with accessory glands like the seminal vesicles or prostate - Sexual dysfunction All these can impair male reproductive function and cause infertility. The specific contributing factors are numerous.
A normally fertile man must meet the following conditions:
① Possess normal reproductive organs and functions; ② Maintain normal sexual function; ③ Lack antibodies in the body that cause sperm agglutination or immobilization. One prerequisite for conception is the man's ability to produce sufficient quantities of healthy sperm and deliver them to the appropriate location within the female reproductive tract. Abnormalities at any stage of this process can cause infertility.
Specifically, numerous factors contribute to male infertility. Classification by etiology includes: ① Congenital developmental abnormalities; ② Infertility due to genetic disorders; ③ Infertility caused by endocrine diseases; ④ Infertility resulting from reproductive tract infections; ⑤ Infertility associated with varicocele; ⑥ Infertility stemming from sexual dysfunction; ⑦ Infertility induced by physical and chemical factors; ⑧ Infertility related to psychological and mental factors.
Classification by semen characteristics:① Azoospermia; ② Oligospermia; ③ Asthenospermia and necrospermia; ④ Seminal fluid non-liquefaction; ⑤ Excessive sperm abnormalities; ⑥ Abnormal semen volume; ⑦ Abnormal semen pH, etc.
Classified by pathological nature: divided into organic and functional infertility. Organic infertility refers to infertility caused by pathological changes in the reproductive organs and adjacent tissues;Functional infertility primarily refers to cases where examinations reveal no pathological changes but only sexual dysfunction.
Classification by prognosis: Divided into absolute infertility (e.g., congenital developmental abnormalities, azoospermia) and relative infertility. The former cannot achieve conception even with treatment, while the latter may restore fertility through treatment.
Preventing and treating infertility requires a four-point approach:
1.Timely vaccination and good personal hygiene are essential to prevent infectious diseases that harm male fertility, such as mumps and sexually transmitted infections. 2. Acquire basic sexual health knowledge, including understanding male physiology and health practices. If any unusual changes in the testicles are noticed—such as swelling, hardening, unevenness, or pain—seek prompt medical evaluation.
3. If you frequently handle radioactive materials, high temperatures, or toxic substances, strictly adhere to operational protocols and protective guidelines. Never be careless. If you plan to conceive soon, it's best to avoid such work for at least six months before trying to conceive.
4. Testicles are highly sensitive organs that function optimally at temperatures approximately 1°C lower than body temperature. Elevated temperatures impair sperm production. Avoid activities that raise scrotal temperature, such as prolonged bicycle riding, hot baths, or wearing tight jeans.
5. Modify unhealthy habits: quit smoking and drinking; avoid excessively greasy foods, which can diminish libido; additionally, take care to avoid exposure to toxic substances in daily life.
