Is infertility related to sex life?

        Medical research believes that common sexual behaviors that lead to infertility include the following symptoms:

　　ejaculation The reason why you get pregnant after having sex is because sperm It meets egg cells and combines to form a fertilized egg. If there is no ejaculation during sexual intercourse, sperm and eggs cannot meet, and pregnancy will be impossible. The causes of non-ejaculation are both mental and organic.

　　Psychological factors are fear of pregnancy or temporary desire not to have children, so the person interrupts sexual intercourse and deliberately does not ejaculate.； Organic factors are due to certain urogenital tract organs sexually transmitted diseases Changes that prevent semen from being discharged from the body, such as congenital absence of the vas deferens or obstruction of the vas deferens.

　　Anejaculation is the inability to ejaculate and there is no orgasm. The difference between anejaculation and anejaculation is that the former does not have the ability to ejaculate, while the latter has the ability to ejaculate but does not allow the semen to ejaculate outside the body due to subjective consciousness or reasons. disease Factor semen cannot be ejaculated outside the body.

　　Impotence The so-called impotence refers to the inability of the penis to erect during sexual intercourse or, although it can erect, it is not hard, making it impossible to complete sexual intercourse. Since you can't have sexual intercourse, you certainly can't get pregnant.

　　The ovulation date for women who have sex during the non-ovulatory period is basically about two weeks before the next menstrual period. Only by having sex 2-3 days before and after the ovulation period can pregnancy be possible. This period is called the "fertile period" and is a "dangerous period" for couples who want to avoid pregnancy. If you have intercourse during a non-ovulatory period, you will not get pregnant because ovulation will not occur.

　　Vaginismus: Due to vaginismus, sexual intercourse cannot proceed smoothly, leading to secondary infertility.

　　The frequency of sexual intercourse is too frequent. Some couples believe that increasing the frequency of sexual intercourse can increase the chance of pregnancy, so they have frequent sexual intercourse. As a result, there is still no hope of getting pregnant. The reason is that excessive sexual intercourse can reduce the number and quality of sperm, and even the ejaculated sperm may be immature sperm, so pregnancy cannot occur. Only by having sexual intercourse regularly can the quantity and quality of sperm be ensured and pregnancy possible.

　　If the frequency of sexual intercourse is too few, the sperm and eggs will have less chance to meet, making it difficult to conceive. In addition, too few sexual intercourses will result in too long intercourse intervals. In this way, the sperm excreted from the body will be of low quality or "aging", which is also not conducive to pregnancy.

　　Retrograde ejaculation Normally, sperm should be ejaculated outside the body. If the sperm flows backwards into the bladder instead of being ejaculated outside the body, this is called retrograde ejaculation. male The urethra has both functions of ejaculation and urination. When the bladder sphincter contracts, urine is "closed" in the bladder. If the bladder sphincter relaxes, urine will pass out of the body. In addition, the urethra passes through the urogenital septum, which is equivalent to the junction of the middle third and the inner third of the urethra, and there is also a membranous urethral sphincter. This sphincter has nothing to do with urination and only comes into play during ejaculation. During ejaculation, the bladder sphincter contracts, the urethral membranous sphincter begins to relax, and the accumulated semen is ejected from the urethral opening. This is normal and ejaculation occurs. If there is a problem with these complex anatomical structures and physiological functions, the contraction rhythm of the vas deferens, etc. is disordered during ejaculation, or the bladder sphincter does not contract at the same time, the semen will not be discharged from the urethra and enter the bladder retrogradely. This is retrograde ejaculation. In addition to functional factors, there are also organic causes of retrograde ejaculation, such as urethral stricture, hypertrophy of the spermatheca, bladder neck dysfunction caused by juvenile diabetes, and surgical damage to the sphincter. 　　Sexual intercourse technique errors. For example, do not have sex in the vagina, and the sexual position is not conducive to the semen reaching the cervix.

　　Therefore, couples who are infertile after marriage have no choice but to go to Hospital In addition to physical and genitourinary system examinations and endocrine examinations, the cause should also be found in sexual life.
