Common classification methods for infertility mainly include the following types:

The first type is based on medical history, which can be divided into primary infertility and secondary infertility. Primary infertility refers to never having been pregnant; secondary infertility refers to having been pregnant before, but after trying to conceive for more than a year, despite having regular sexual intercourse without contraception, there has been no pregnancy.

The second type is based on the treatment conditions, which can be divided into absolute infertility and relative infertility. Based on the results of treatment, it can further be classified into temporary infertility and permanent infertility.

The third type is based on the causes of infertility, which can be divided into male infertility, female infertility, and infertility affecting both partners.

Can biochemical energy eliminate infertility?

Having one biochemical pregnancy does not necessarily mean that the patient is infertile. Generally, after one biochemical pregnancy, with appropriate adjustment, it is possible to have a normal pregnancy next time. The causes of biochemical pregnancy result from natural selection, most commonly due to defects in the fertilized egg itself, insufficient function of the ovarian corpus luteum, abnormalities in the endometrium, underdeveloped uterus, or conditions such as uterine fibroids or endometrial tuberculosis. These factors can affect the implantation of the fertilized egg. It is advised to undergo thorough pre-pregnancy checks before attempting to conceive again.

What tests are done for secondary infertility?

The most common cause of secondary infertility in women is blocked fallopian tubes. In this case, a hysterosalpingography with iodine oil should be performed to understand the patency of the fallopian tubes and the specific location of the blockage, which can guide future treatment. Additionally, if a woman has abnormal vaginal discharge, a routine gynecological examination should be conducted to check for any cervical lesions. A vaginal secretion test should be performed to see if vaginal inflammation is affecting normal pregnancy. Some women experience infertility after having an abortion or induced abortion, and for these women, it's also worth considering whether uterine issues are causing secondary infertility. A hysteroscopy can be done to investigate this. When a woman experiences secondary infertility, her sexual partner or spouse should also be examined to assess sperm quality and any potential obstacles in the sperm delivery pathway.

Secondary infertility refers to a condition where a person is unable to become pregnant or carry a pregnancy to term following the birth of one or more biological children.

Infertility is divided into primary infertility and secondary infertility. Primary infertility refers to never having been pregnant before, which is called primary infertility. Secondary infertility generally occurs in individuals who have had children or a history of miscarriage and have been unable to conceive again after trying for a year, thus constituting secondary infertility. It is essential for those with secondary infertility to undergo relevant fertility tests at a hospital. Typically, the clinical evaluation includes a semen analysis for the male partner, and for the female partner, tests such as Mycoplasma and Chlamydia detection, endocrine examinations, immunological tests, and assessments for fallopian tube patency and related endocrine tests. Generally, through these tests, the cause of secondary infertility can be identified, and treatment can be tailored based on the results. In cases of secondary infertility, the vast majority can achieve conception through targeted treatment.

Why am I infertile after a cesarean section?

Infertility after cesarean section may be due to the manipulation of surgical instruments on the uterus or postoperative puerperal infection, leading to pelvic inflammation and fallopian tube blockage, resulting in infertility. Therefore, it is crucial to pay attention to hygiene during the puerperium after a cesarean section, monitor the recovery of the uterus and the lochia, and observe the color and odor of the lochia daily. If the uterus does not recover well, and the lochia is excessive or persists for a long time, it is important to seek medical advice early. If there is a foul odor, timely treatment is necessary to avoid chronic pelvic inflammatory disease. It is also essential to get out of bed and move around timely to prevent the formation of venous thrombosis.
