Infertility needs to be treated according to the cause, as follows: 1. Generally, in young patients with good ovarian function and less than three years of infertility, expectant treatment is performed first. However, if the fallopian tubes have severe hydrocele, tubal resection or blockage should be done. Because the fallopian tube is waterlogged, it is no longer functional, or serious adhesions there is no hope to get pregnant on their own again, this kind of laparoscopy or hysterolaparoscopy should be done, and the fallopian tube should be cut during the examination, in preparation for the next step of assisted reproduction technology, you can go for IVF; 2. For larger ovarian tumors or those of unknown nature, surgery should be done first, to do surgery is to exclude whether the nature of the tumor is malignant or benign, surgery to remove If there are submucosal fibroids or submucosal polyps in the uterus, hysteroscopic examination should be done to remove the submucosal fibroids or polyps under hysteroscopy. If there are adhesions, the adhesions can be separated, as well as those with deformities can also be corrected, so surgery is also important. 4. Endometriosis affects pregnancy, but laparoscopic diagnosis and treatment are generally preferred. Generally after the ectopic lesions are treated, the structure of the pelvic cavity is restored and the environment for conception is improved, and after all these unfavorable factors are removed, pregnancy is facilitated; 5, reproductive system tuberculosis, tuberculosis most damaged is the endometrium of the fallopian tubes and the endometrium of the uterus, it will affect menstruation and lead to non-pregnancy, so the time active period must be treated with anti-TB first, that is, anti-tuberculosis treatment. However, strict contraception should be used during the medication period and pregnancy should be considered after satisfactory anti-TB treatment for TB. This is because most patients with pelvic tuberculosis take a long time to treat, and anti-TB treatment takes at least six months to nine months. Even if they cannot conceive on their own, these patients can still conceive with the help of assisted reproductive technology.
