Since ancient times, couples have no children, and it is natural to conclude that women's stomachs are not competitive. "His daughter-in-law will not give birth
During pregnancy preparation, many people will also think that it is women's business to be pregnant as long as men can successfully ovulate. It is also time to rectify the black pot that has been carried by women for many years. In fact, infertility should be traced back to the cause, and the probability of both husband and wife is basically equal.
Let's talk about it today
Those fallacies in infertility treatment!
Let's see what they say first~~
"My husband can eat and sleep, exercise every week,
Take a cold bath in winter,
I don't catch a cold once a year,
How could he have a problem? "
"Doctor, my husband shoots a lot every time
Could it be his reason? "
"Is there a problem with my fertility? How can it be!
My children are so old! "
After reading so many words
Beidajun can't help revealing the truth!!
Normal sexual function does not mean normal reproductive function
Male reproductive ability and sexual ability are two completely different mechanisms. The androgens that produce sexual function are in the interstitial cells of the testis, while the sperm comes from the spermatogonia in the testis. These two mechanisms are combined to complete fertility, but they cannot affect each other. Men with sexual dysfunction sometimes do not affect fertility.
Premature ejaculation can make a woman pregnant. While some patients with azoospermia have normal sexual function, they do not have reproductive function without sperm in semen.
Having a history of pregnancy does not mean having fertility function all the time
Some people will think that as long as they have a history of pregnancy, they will always have fertility function. This situation mostly occurs in men who remarry, have a second child, or have miscarriage. Clinically, it is often heard that "the husband is OK, his previous girlfriend was pregnant" or "the husband had children in his last marriage". In fact, the past fertility situation does not mean that the fertility function has been normal.
According to clinical manifestations, male infertility can be divided into absolute infertility and relative infertility. Relative infertility means that the patient has certain fertility, but the fertility is lower than the critical value required for pregnancy, such as oligospermia; Absolute infertility means that the patient has no fertility at all, such as azoospermia.
"Excellent" does not mean "excellent"
Some people believe that the ability to ejaculate means that sperm is normal and fertile, but in fact, it is not. Although sperm is essential for pregnancy, "having sperm" is not equal to "excellent sperm", but there must be certain indicators. The normal sperm volume should be 20 million sperm per milliliter of semen, the sperm deformity rate should be less than 15%, and the sperm vitality should reach Grade A sperm>25% or Grade A+B sperm>50%. These indicators can represent fertility.
Methods of male infertility test
Semen is a necessary material for fertility, so it is necessary to check semen, including semen volume, color, pH, semen liquefaction time, sperm density, sperm activity and sperm morphology.
Generally, abnormal reproductive organs will also have an impact on fertility. The contents of this examination include: visual and palpation of penis, urethra, testicle, seminal vesicle, prostate, etc. Check whether there is serious phimosis, induration, inflammation, and dysplasia.
Examination of prostatic fluid
Generally, the normal prostatic fluid is milky white and weakly acidic, and the white blood cells are less than 10 under high power microscope. If the male prostate is abnormal, it will lead to the increase of white blood cells.
Check for antisperm antibodies. At present, the commonly used methods include sperm agglutination test, sperm immobilization test, solid phase enzyme test, post-test, etc.
sperm penetration test,spt
Normal sperm does not necessarily represent that sperm has penetration ability, and further sperm penetration test must be carried out, because the penetration ability of sperm is the actual fertility of men.
