If it is infertility, treatment is relatively difficult and generally not easy. First, for secondary infertility, it depends on the cause. If it's due to fallopian tube blockage, the extent of the blockage needs to be considered. If it is because the ovaries do not ovulate, then it is necessary to go to the hospital for endocrine testing. Treatment should be based on the results of the endocrine tests, and only when hormone levels are normal will there be normal ovulation and clear fallopian tubes. Without problems related to immunity, it is possible to properly prepare for pregnancy. Therefore, if it is secondary infertility, it is essential to go to the hospital for infertility-related examinations to identify any abnormalities and treat them accordingly. Both primary and secondary infertility are difficult to treat.
