Menopause is the last spontaneous menstruation in a woman's life. It is diagnosed retrospectively after 12 months of no menstruation. The average age of menopause in Russia is 51–52 years.
Menopause occurs as a result of the natural decline in ovarian function and the cessation of estrogen secretion. It is not a disease, but a physiological transition. However, estrogen deficiency affects virtually all organ systems, and for a significant number of women, this transition is accompanied by severe symptoms that reduce quality of life.
According to the new 2025 ROAG clinical guidelines, which came into effect and replaced the 2021 version, the terminology has been clarified:
| Indicator | What is assessed |
|---|---|
| FSH | An increase of ≥25 IU/L in two measurements confirms postmenopause |
| Estradiol (E2) | Decrease < 20–30 pg/ml |
| AMH (anti-Müllerian hormone) | Marker of ovarian reserve; decreases long before clinical menopause |
| TSH | Ruling out hypothyroidism (a common cause of menopause-like symptoms) |
| Prolactin | Ruling out hyperprolactinemia |
DXA (densitometry) of the lumbar spine and proximal femur is recommended for all peri- and postmenopausal women to detect osteoporosis and assess fracture risk.
Mammography is a mandatory screening before starting HRT.
Pelvic ultrasound is an assessment of the endometrium and ovaries.
FRAX is a 10-year fracture risk calculator.
MHT is the most effective method for correcting menopausal symptoms. According to the updated 2025 guidelines for the Russian Society of Gynecologists, the approach to MHT has become more personalized: the restrictive phrases "only when clearly indicated" have been replaced by the principle of an individual assessment of the balance of benefits and risks at least once a year.
Oral (tablets) — convenient, but pass through the liver.
Transdermal (patches, gels) — preferred for those with a high risk of thrombosis, obesity, and metabolic disorders.
Intravaginal (for GUMS) — minimal systemic absorption, high local efficacy.
Follow-up examination 3 months after starting HRT, then at least once a year:
If HRT is contraindicated or the patient refuses:
Menopause (climacteric) is a broader term: it encompasses the entire transitional period of a woman's life, including perimenopause and postmenopause. Menopause refers to a specific moment (the last menstrual period). In common parlance, the terms are used interchangeably.
On average, it lasts 5–7 years, but for some women, it lasts longer. Without treatment, hot flashes persist for more than 10 years in 30% of women. HRT eliminates hot flashes in 90% of patients.
The risk of breast cancer with combined HRT is slightly increased with use for more than 5 years and levels off after a few years of discontinuation. This risk is comparable to that of excess weight or drinking a glass of alcohol daily. Mammography is mandatory before starting HRT, and then annually thereafter.
Use with caution. There is a concept called a "window of opportunity": HRT is most effective and safe when started within 10 years of menopause or before age 60. After age 60 or with prolonged postmenopause, the risks of HRT (including cardiovascular risks) increase.
Yes, as long as you haven't had a period for 12 months (that is, until menopause is confirmed). Ovulation is still possible during perimenopause.
Often, both. Estrogen deficiency reduces the brain's sensitivity to serotonin and dopamine, which intensifies depressive symptoms. Assessing hormonal status helps differentiate between "pure" depression and menopausal depressive syndrome.
This is menopause resulting from bilateral oophorectomy (removal of the ovaries). It occurs immediately and is typically more severe than natural menopause due to the sharp drop in estrogen levels. In such cases, HRT is especially important and is recommended until the age of natural menopause.
