Menopausal syndrome
Menopausal syndrome, also known as perimenopausal syndrome, refers to a group of symptoms primarily characterized by autonomic nervous system dysfunction, accompanied by neuropsychological symptoms, caused by fluctuations or decreases in sex hormones around the time of menopause. Epidemiological studies show that the average age of natural menopause for women in China is approximately 50 years old.
View detailsFetal demise
Fetal arrest refers to the phenomenon where an embryo dies and stops developing at a certain stage. Clinically, pregnancy symptoms such as nausea and vomiting disappear, and signs of threatened miscarriage such as vaginal bleeding and abdominal pain may occur. Some patients have no clinical symptoms and are only diagnosed during an ultrasound examination.

Female genital congenital malformations refer to congenital deformities of the female reproductive organs, which commonly include: Uterine developmental malformations: uterus didelphys, rudimentary horn uterus, septate uterus, congenital absence of the uterus, etc. Vulvovaginal developmental malformations: imperforate hymen, congenital absence of the vagina, transverse vaginal septum, longitudinal vaginal septum, oblique vaginal septum, double vagina, etc.
Miscarriage
In China, the termination of pregnancy before 28 weeks of gestation, with a fetal weight of less than 1,000 grams, is defined as abortion. According to the different stages of occurrence, it can be divided into: Early abortion: Occurs before 12 weeks of gestation. Late abortion: Occurs after 12 weeks of gestation. According to the different causes of occurrence, it can be divided into: Spontaneous abortion: The embryo or fetus develops in the uterus for too short a time to continue the pregnancy. Induced abortion: Termination of pregnancy by artificial means due to unintended pregnancy or medical reasons. Typically, after embryo implantation, about 3/10 of pregnancies result in spontaneous abortion, with the vast majority (about 80%) being early abortions. Among early abortions, more than half are cryptic abortions, meaning they occur before the menstrual period. The main symptoms are vaginal bleeding and abdominal pain.
View detailsMorning sickness
Morning sickness refers to a series of symptoms that occur in early pregnancy (usually around 6-12 weeks after the last menstrual period) due to a rapid increase in gonadotropins (mainly human chorionic gonadotropin, HCG), increased brain excitability, and psychological factors. The main manifestations of morning sickness include loss of appetite, nausea, morning vomiting, craving for sour foods, fatigue, and dizziness. These symptoms generally do not require special treatment and usually lessen or disappear naturally after 12 weeks of pregnancy as HCG levels in the body decrease.
View detailsThreatened abortion
Threatened miscarriage refers to vaginal bleeding, which may be accompanied by paroxysmal abdominal pain, occurring within 28 weeks of pregnancy. However, the cervix is not dilated, the membranes are intact, the uterine size is consistent with the gestational age, and there is no expulsion of gestational tissue. Threatened miscarriage is the earliest stage of spontaneous miscarriage, with the main symptoms being vaginal bleeding and abdominal pain.
View detailsRecurrent miscarriage
Recurrent miscarriage refers to the loss of a fetus before 28 weeks of gestation in three or more consecutive pregnancies with the same partner. It is characterized by miscarriages often occurring in the same month of pregnancy, and the course of each spontaneous miscarriage is roughly similar. Maternal obesity is a high-risk factor for recurrent miscarriage.
View detailsAmenorrhea
Amenorrhea refers to the absence of menstruation in females or the cessation of menstruation after its establishment. It can be divided into physiological amenorrhea and pathological amenorrhea. Physiological amenorrhea refers to the absence of menstruation before puberty, during pregnancy, lactation, and after menopause, which is a normal physiological phenomenon. Clinically, amenorrhea usually refers to pathological amenorrhea, which means that a woman has not had menstruation or menstruation has stopped after puberty or after puberty but before menopause, excluding pregnancy.
View detailsHyperprolactinemia
Hyperprolactinemia is a condition characterized by abnormally elevated serum prolactin levels due to various causes. It can affect both men and women, though it is more common in women. Typical clinical symptoms of hyperprolactinemia in women include menstrual irregularities, galactorrhea, infertility, and sexual dysfunction. In men, typical clinical symptoms include sexual dysfunction, decreased secondary sexual characteristics, and oligozoospermia or infertility.
