This is a clinical condition in which the woman is said to be infertile and the man is said to be infertile when she fails to achieve a clinical pregnancy after at least 12 months of regular sexual intercourse without the use of contraception. A woman with no previous history of clinical pregnancy is considered primary infertility; a woman with a previous history of clinical pregnancy is considered secondary infertility. Couples who meet the definition of infertility are recommended to be seen at the same time for a primary history taking and physical examination. The fertility of the couple is initially assessed by routine semen analysis in the man, pelvic ultrasound in the woman, basic endocrinology, and monitoring of ovulation during a natural cycle. Male semen routine if abnormal, male management. If the semen routine of the male partner is normal, the female partner can be given treatment if ovulation disorder is found. Hyperandrogenism, after ruling out androgens of adrenal and tumor origin, can be given endocrine modifying treatments, e.g., some short-acting oral contraceptives. Hyperprolactinemia, can be given drugs to reduce prolactin therapy. After the endocrine adjustment, there is still no natural ovulation, can be given to promote ovulation treatment, if there is ovulation, and according to the doctor’s advice of coitus for 3 cycles, but still not pregnant, then consider the degree of tubal patency examination. If there is no special finding in the above examination and pelvic examination considers pelvic inflammation, then tubal patency examination can be performed. The tubal test is a mildly invasive test compared to the previous tests. Therefore, it is recommended that a semen test be performed on the male partner before this test is performed. If the man is azoospermic, or has severe oligospermia, the woman can proceed directly to in vitro fertilization (IVF-ET) without a tubal test. There are many types of tubal tests. There are four main types: Hysterosalpingography (HSG), Tubal Fluidization, Tubal Ultrasonography and Hysteroscopic Fluidization. Based on the evaluation of these tests, the etiologic diagnosis is completed by taking into account the specific history and clinical manifestations of the infertile couple. The etiologic categories are clearly defined and include: female infertility (ovulatory disorders, pelvic factors), male infertility and unexplained infertility. If pelvic factor infertility, bilateral tubal obstruction, can be directly in vitro fertilization (IVF-ET) treatment; if tubal obstruction, multiple ultrasound suggests that one or both sides of the fallopian tubes hydrocele, it is recommended to carry out laparoscopic diagnosis and treatment, and during the operation, if it is found that the hydrocele is serious and the tubal dilatation and adhesion is serious, it is recommended to carry out the affected side of the salpingo-oophorectomy; the majority of the cases are the tubal communication but not fluent, and it is possible to carry out the Pelvic inflammatory disease treatment combined with Chinese medicine enema, physiotherapy, if still unable to get pregnant, can be carried out hysterolaparoscopy joint diagnostic surgery, to find the cause of the disease and surgical treatment, if the combination of ovarian cysts or uterine fibroids can be operated at the same time; can also be based on the infertility of the years, if more than 5 years, can be directly for diagnostic artificial insemination treatment, if 3 to 4 cycles are still not pregnant, can be carried out in vitro fertilization (IVF-ET) treatment. ET) treatment. Unexplained infertility can be treated with diagnostic artificial insemination and, if there is no pregnancy after 3 to 4 cycles, with in vitro fertilization (IVF-ET).
