Women with high prolactin may not have dominant follicles because the body’s estrogen levels will be lower. Prolactin is also known as prolactin, and if it is too high, it is hyperprolactinemia. If a woman’s prolactin is too high, the pituitary gland’s secretion of luteinizing hormone and follicle-stimulating hormone is suppressed, resulting in lower estrogen levels in the body. In this low estrogen state, which leads to poor follicular development, infertility may result. With hyperprolactinemia, the patient may present with scanty, scanty or amenorrheic periods and may have nipple discharge. Because of the low estrogen levels, there is a risk of thinning or atrophy of the vaginal walls, decreased discharge, and loss of libido. If it is determined that it is hyperprolactinemia, further examination is needed first to clarify the cause of the disease, and treatment for the cause of the disease, such as bromocriptine mesylate and vitamin B6 can be taken; if it is a pituitary prolactinoma caused by high prolactin, and the effect of the medication is not good, then it may need to be done surgically.
