A friend decided to have a second child when her eldest child was in her teens, but after a long time of preparation, there was no sign of movement, and she had no doubts about her fertility because she had outlived her first child. However, after gynecological examination, there is no fertility abnormality, but experienced gynecologists found pituitary gland abnormality after having the patient undergo cranial ct. Some women who are infertile after marriage will go to the gynecology department and the men’s department for a physical examination of the couple, and if the cause is not known, they can only wait, often ignoring the culprit of endocrine abnormality that leads to infertility: “pituitary tumor”. In fact, pituitary tumors can also cause infertility! The pituitary gland and the hypothalamus together dominate the body’s endocrine system. Pituitary tumors mostly occur in women of childbearing age. In addition to general symptoms such as dizziness, headache, vomiting, etc., female patients may also experience endocrine disorders such as lactation, menstrual disorders, amenorrhea and infertility. Patients with infertility due to pituitary tumor may fail during pregnancy due to hormonal abnormalities in the body even if they are artificially inseminated. This shows that the brain and the limbs are harmonized, and that intracranial disorders can also lead to “tummy” problems. Women who are infertile after marriage, or women who experience unexplained menopause for 3 months, accompanied by symptoms such as lactation, dramatic vision loss, diplopia, and unexplained headaches, and who cannot find a clear reason for their condition in the appropriate specialty, should go to the neurosurgery and endocrinology departments in time to undergo an examination. When the pituitary tumor is cured, having children is still completely possible.
