Couples who become infertile after marriage should not only go to the hospital for a full body and urogenital system examination, as well as endocrine tests, but also find reasons for their sexual activity. Medical research suggests that common sexual activities that lead to infertility have the following symptoms:
1. Ejaculation incompetence. No ejaculation ability or orgasm. The difference between ejaculation incompetence and non ejaculation is that the former has no ability to ejaculate, while the latter has the ability to ejaculate but is unable to ejaculate out of the body due to subjective consciousness or due to disease factors.
2. Having sexual activity during non ovulatory period. Women's ovulation period is usually around 2 weeks before the next menstrual cycle, and they have sex 2-3 days before and after ovulation, which may lead to conception. Having sex during non ovulatory periods will not lead to pregnancy.
3. Vaginal spasms. Due to vaginal spasms, sexual activity cannot proceed smoothly, leading to secondary infertility.
4. Excessive sexual activity. Excessive sexual activity can lead to a decrease in sperm count, decreased motility, and even the ejaculation of immature sperm, making it difficult to conceive. Regular sexual activity can ensure the quantity and quality of sperm in order to conceive.
5. Excessive sexual activity. Having too little sexual activity and having fewer opportunities for sperm and egg encounters makes it difficult to conceive. Long intervals between sexual activities can also lead to low sperm quality, which is not conducive to pregnancy.
6. Retrograde ejaculation. Under normal circumstances, sperm should be ejaculated outside the body. If the anatomical structure or physiological function of the male has problems, the contraction rhythm of the vas deferens is disordered during ejaculation, or the bladder sphincter does not contract at the same time, the semen cannot be discharged from the urethra, but enters the bladder retrogradely, which is called retrograde ejaculation. In addition to functional factors, there are also organic reasons for retrograde ejaculation, such as urethral stricture, hypertrophy of seminal caruncle, dysfunction of bladder neck caused by young diabetes, and surgical injury of the sphincter.
7. Action error. For example, if the penis is not inserted into the vagina, or if the sexual position is not conducive to semen reaching the cervix, etc.
