Currently, women in the Armed Forces of the Russian Federation are trained in higher flight educational institutions, including the Faculty of Fighter Aviation. In 2022, the first issue of female pilots was conducted. However, the existing selection system, including assessment and training of statokinetic stability, is based on male physiological characteristics and does not consider cyclic hormonal changes occurring in a woman’s body during the ovarian–menstrual cycle.

Abstract:
Menstrual cycle disorders are the main symptom of anovulation, a phenomenon accompanied by decreased ovarian steroid secretion and production. Weight gain and an increase in adipose tissue in obese women, especially in the midsection, can disrupt the balance of steroid hormones such as androgens, estrogens, and sex hormone-binding globulins, which can affect the menstrual cycle in adolescents. The mechanism of obesity that is most often associated with menstrual cycle disorders.

A growing body of literature demonstrates strong effects of ovarian hormones on the hippocampus and adjacent structures. However, resulting impacts on human cognition remain unclear. Addressing this gap, we examine pattern separation ability, a core hippocampal process, across the menstrual cycle using the mnemonic similarity task as a behavioral index (N = 183). We find a non-linear effect of the menstrual cycle, with pattern separation performance peaking in the high-estradiol, late follicular phase and reaching its lowest point during the mid-luteal phase, which is characterized by moderate

Introduction. Cytochrome P450 aromatase is a key enzyme in the biosynthesis of estrogens from androgens. Some gynecological diseases are accompanied with changes in the activity of ovarian aromatase. Moreover, changes in the acti vity of ovarian aromatase are associated with the response to standard gonadotrophin stimulation in women undergoing in vitro fertilization. A new effective method determining the activity of ovarian aromatase without using ovarian tissue biopsy has been developed.
