According to research in recent years, as far as the current level of medical science is concerned, the possible causes of infertile infertility are as follows:

(1) Immune factors. The woman's serum or cervical mucus contains anti-sperm antibodies, which make the sperm agglomerate and affect the sperm vitality.

(2) The egg is not healthy, although ovulation cannot be achieved.

(3) Insufficient endocrine function.

(4) The luteinized unruptured follicles appear to have ovulated from the basal body temperature curve, but the ovulation does not actually occur and the follicles directly develop

Luteinization.

(5) The uterus tilts backwards.

(6) Recessive abortion.

(7) Other. Such as overload of thought, anxiety, occult systemic diseases, men with mild sexual dysfunction, reduced number of sexual intercourse and so on.

Laparoscopy: diagnosis of mild pelvic endometriosis and treatment at the same time.

Immunological examination: Use blood, semen, cervical mucus to detect immune infertility caused by anti-sperm antibodies, anti-ovum antibody, anti-endometrial antibodies, ovarian antibodies, etc. Anti-sperm antibody immunity can also be used for diagnosis of sperm agglutination test, sperm braking test and sexual intercourse test.

Examination of cervical mucus properties: Generally, changes in cervical mucus can be observed during ovulation, and cervical mucus can be taken for microscopic examination to see the crystals of sheep teeth to understand whether mucus is conducive to sperm penetration and into the cervix.

Ultrasound of the vagina: follow-up of follicles during the predicted ovulation period, you can know whether there is ovulation or the phenomenon of ovulation, and understand the endometrial thickness and the effect of estrogen on the endometrium.

Measurement of basal body temperature: The basal body temperature curve can reflect whether the ovarian corpus luteum is healthy.

Careful gynecological examination and B-ultrasound examination: Neglected uterine dysplasia can be found.

Comprehensive collection of medical history: The effects of mental and psychological factors on endocrine function and germ cells can be found. Through necessary further testing, most related causes of "unknown infertility" can be found, and then treatment can be based on the cause to increase the pregnancy rate. .
