1. What is hyperprolactinemia ?
Hyperprolactinemia is a hypothalamic-pituitary dysfunction disease. Due to various reasons, the body's serum prolactin level continues to be higher than the normal value. In terms of clinical manifestations, the main symptoms in women are amenorrhea, galactorrhea, oligomenorrhea, infertility, etc. In men, the main symptoms are loss of sexual desire, erectile dysfunction, reduced sperm count, infertility, osteoporosis, etc.
2. How does hyperprolactinemia occur?
There are many reasons for the increase in prolactin, including physiological factors, drug factors, disease factors, etc.
Physiological factors include exercise, eating, sleep, sexual life, breastfeeding, pregnancy, stress conditions (such as surgery, hypoglycemia, myocardial infarction, syncope, trauma, etc.), etc. The increase in blood prolactin caused by physiological factors is generally not serious, does not fall into the category of disease, and does not require special treatment.
Long-term use of certain drugs, such as dopamine receptor antagonists, antidepressants, estrogen, and birth control pills, can also lead to a mild increase in prolactin.
The most important thing is disease factors, which mainly include pituitary disease, hypothalamic disease, primary hypothyroidism, chronic systemic diseases, polycystic ovary syndrome , etc. The mechanism by which these diseases cause the increase in prolactin is roughly as follows The following types: First, the "autonomous secretion" type, that is, uncontrolled autonomous secretion, leading to an increase in prolactin; the second is the "instruction disorder" type, that is, the pituitary gland that secretes prolactin cannot receive normal instructions or receives wrong instructions, resulting in the secretion of too much prolactin; the third is " The "outward blocked" type means that the prolactin secreted into the blood cannot be cleared or inactivated in time, resulting in an increase in serum prolactin levels.
3. How does hyperprolactinemia lead to infertility ?
The basis for female pregnancy is to have mature follicles and regular ovulation, which requires the support and guarantee of gonadotropins secreted by the pituitary gland. When hyperprolactinemia occurs, will negatively feedback to inhibit pituitary function. Once the pituitary function is inhibited, the synthesis and secretion of gonadotropin will be affected, which will affect the development and maturation of follicles, as well as the synthesis of estrogen in the ovary. , progesterone, eventually leading to follicular dysplasia or non-ovulation, sparse menstruation or amenorrhea, leading to infertility.
4. What situations require investigation of hyperprolactinemia?



4. Symptoms caused by reduced sex hormones: such as breast atrophy, pubic hair loss, vaginal dryness, etc. in women; sparse beards, slow growth, and sparse pubic hair in men.
5. Infertility, infertility.
Hyperprolactinemia is a disease that is not uncommon clinically. Because it affects fertility, it troubles many families. Just like the couple of childbearing age mentioned at the beginning of this article, they were unable to get pregnant after 8 years of marriage. But fortunately, with active diagnosis and treatment, most patients can achieve good results. For example, this young couple gave birth to a healthy baby girl soon after the doctor’s correct diagnosis and treatment, and the wife Li’s compliance with the doctor’s instructions, simple surgical treatment, medication under the doctor’s guidance and regular review and follow-up. , the whole family is very happy
