A pituitary tumor is the occurrence of a tumor located in the pituitary gland. This tumor causes the pituitary gland to make too much or too little hormone that affects the functions of the body. Many pregnancies with pituitary tumors cause many difficulties for the patient and the fetus.1. What is high prolactin during pregnancy?
High prolactin during pregnancy is caused by an abnormal growth of a tumor in the pituitary gland. High prolactin during pregnancy is seen in pituitary adenoma. A part of the brain responsible for regulating the balance of hormones (hormones) of the body. But the very appearance of a pituitary tumor can lead to the overproduction of hormones that control the body's functions. Or conversely, some pituitary tumors appear, causing the production of hormones to be less, resulting in the body not having enough of the necessary hormones.
Most pituitary tumors are benign (non-cancerous, also called adenomas). The pituitary tumor will still exist or grow in the pituitary gland or surrounding tissues but will not spread to other parts of the body.
Pituitary tumors cause infertility by secreting the hormone prolactin leading to a decrease in sex hormones (estrogen in women and testosterone in men). Too much prolactin in the blood affects men and women in different ways. In women, prolactin-secreting pituitary tumors can disrupt the body's hormonal balance, inhibit ovulation, and cause infertility. female.
High prolactin can prevent ovulation in women. When this happens, a woman's menstrual cycle will stop completely (amenorrhea) and she will lose the ability to have children. To a lesser extent, people with high prolactin levels still have normal periods, still ovulate, but do not produce enough progesterone hormone after ovulation, making the fertilized egg unable to implant, leading to infertility in women. female.
