THE SPECIFICITY OF THE OVARIAN RESERVE OF WOMEN WITH CHRONIC SALPINGOOPHORITIS

Abstract

Aim. The research was conducted for the assessment of the impact of chronic salpingoophoritis on the ovarian reserve of women in various phases of reproductive age.Materials and methods. A prospective, controlled and open cohort study was performed in 2013-2018 (n=202). The main group consisted of women with chronic salpingoophoritis (ChrSO) who applied for preconception consultation (n=138). In accordance with the reproductive age phase, the main group was divided into subgroups: the early reproductive age period (ERP, n=44), the peak reproductive age period (PRP, n=56), the late reproductive period (LRP, n=38). The control group consisted of conditionally healthy women of reproductive age (n=64). The ovarian reserve (OR) was estimated on the basis of the serum level of antimullerian hormone (AMH), inhibin B, estradiol, follicle stimulating hormone (FSH), an ultrasoundbased assessment of the number of antral follicles (AF), and the ovarian volume. Results. The age of women ranged from 18 to 40 years. Based on the discriminant analysis, it was found that the main indicators determining the specificity of the OR in ChrSO, depending on the phase of reproductive age, are the number of antral follicles, estradiol level and AMH (Wilks’ lambda = 0.35503, p<0.0001). The specificity of the OR of women with ChrSO (difference from the control group), regardless of the phase of reproductive age, initially and when evaluated after 6 months, is determined by the number of AF and the level of estradiol and AMH; the number of AF and AMH is determined with a similar estimate after 12 months. The specificity of the OR in ChrSO, which is dependent on the reproductive age phase, has been proved through the analysis with the neural networks training(the proportion of correct answers is more than 80%). The linear relationships were established between the values of each OR parameter in women with ChrSO. Initially, when estimating after 6 and 12 months, linear regression equations were calculated, allowing the values of individual OR parameters to be calculated over 6 and 12 months.Conclusion. Chronic salpingoophoritis (ChrSO) is associated with a decrease in ovarian reserve in women of reproductive age. The effect of ChrSO on some parameters of the ovarian reserve depends on the age phase of the reproductive period, which increases with time (after 6, 12 months). The presence of ChrSO in women planning future pregnancies requires preventive and therapeutic measures aimed at preserving the ovarian reserve and the preferred implementation of fertility in early reproductive age before the ovarian reserve starts to decline.
