Abstract

Combined oral contraceptives (COC), as drugs containing hormones, can negatively affect sexual function in women of reproductive age. Various causes of sexual dysfunction when taking COC have been studied: a decrease in the concentration of testosterone in the blood due to an increase in globulin, which binds sex steroids, under the influence of oral contraceptives. This mechanism is realized due to the action of two components of COC, both estrogenic and progestogenic. Female sex hormones are known to play an important role in the physiology of sexual desire and behavior. The importance of the most important of them, estrogens, in the sexual behavior of women is to prevent atrophic processes in the vagina, enhance vaginal and vulvar blood circulation, as well as to maintain sensory peripheral perception and the beneficial effect of these processes on the central nervous system. The presented clinical case demonstrates the positive effect of Claira (a drug that is a COC containing estradiol valerate in combination with dienogest with a dynamic dosage regimen) on sexual function. The content of this oral contraceptive of estrogen, identical to natural, eliminates the negative impact of COC on sexual function. Estradiol and estriol, formed during the metabolism of estradiol valerate, actively bind to receptors and have their effects in the tissues of the urogenital tract, having a positive effect on the manifestations of sexual dysfunction. Switching to the drug Clair from other COCs can normalize the condition of women who have decreased sexual function when taking a contraceptive of a different composition and mechanism of action, which was confirmed by this clinical study.
