The present article examines the effectiveness of bariatric surgery in restoring reproductive health in patients with morbid obesity. The medical histories of 270 morbidly obese patients with reproductive dysfunction were studied. The patients were divided into two groups: 181 women and 89 men with a BMI of 45-65 kg/m2. The age of the operated women was 18 to 58 years; 7 patients (3.9% of the women) were in postmenopause. Of the 174 women, 45 were of childbearing age and complained of abnormal ovarian and menstrual function. The number of men was 89 persons aged from 18 to 60 years. The concentrations of hormones such as testosterone, estrogen, and progesterone were studied in the postsurgical period. The data obtained was with the initial figures. Surgical treatment of both sexes resulted in sustained positive results and improved quality of life. Due to bariatric surgery, the patients returned to normal indicators after a certain period, and their reproductive function improved. The reduction of visceral adipose tissue in patients led to the normalization of hormonal background, as evidenced by blood tests. As a consequence, the reproductive function was restored.
