The current view of natural fertility

Introduction. The reproductive experience of women 18–44 years of age is quantitatively superior to adolescent girls. The structure of reproductive losses of adolescents, its identity or difference in comparison with women of reproductive age is extremely unexplored.Aim. To compare the structure of reproductive losses of adolescents and women of reproductive age on the example of the Tyumen region.Materials and methods. A retro-prospective analytical study carried out. Study period – 2016–2021. Adolescent girls and women of reproductive age with completed pregnancies included.Results and discussion. In the Tyumen region, the frequency of reproductive losses approaches childbirth (42.83% and 57.17%), mainly represented by medical abortion (59.98%). The proportion of completed pregnancies among adolescent girls (1.14%) is inferior to women of reproductive age (98.86%). Adolescent girls are characterized by the completion of pregnancy by childbirth (OR = 1.68), a high frequency of medical abortion (OR = 1.71). Reproductive losses up to 12 weeks distinguish completed pregnancies in women of reproductive age (OR = 1.68); unsuccessful abortion attempt, criminal and unspecified types of abortion before 12 weeks and other abnormal products of conception after 12 weeks are their exclusive markers. The pregnancy outcome is associated with age: with adolescents – medical abortion before (OR = 1.71) and after 12 weeks (OR = 2.01); with reproductive age – other abnormal products of conception (OR = 1.64) and ectopic pregnancy (OR = 6.15). Reproductive losses are associated with gestational age before/after 12 weeks: with adolescents – spontaneous abortion after 12 weeks (OR = 2.55); with reproductive age – other types of abortion (OR = 20.37), medical abortion (OR = 1.93), other abnormal products of conception (OR = 1.89) before 12 weeks and spontaneous abortion (OR = 5.42) after 12 weeks.Conclusion. In the Tyumen region, reproductive losses in frequency compete with childbirth. Augmented the concept of the abortion-contraceptive behavior of modern society based on the association of medical abortion with adolescent girls that we have identified. The structure of reproductive losses is associated with a woman’s age period and gestational age.

Introduction. Postponing motherhood correlates with a decrease in natural fertility, the accumulation of aggravated reproductive experience, somatic and other diseases, and, as a result, an increase in the risk of reproductive losses. The present study reflects the significance of intraterritorial differences in the structure and frequency of reproductive losses among female residents of the Tyumen region. Aim. To assess intraterritorial differences in reproductive losses on the example of the Tyumen region.Materials and methods. An analytical study has been carried out. The study period is 2016–2021. Reproductive losses in various autonomous districts of the Tyumen region were analyzed. Used data from medical records.Results and discussion. In Tyumen region, 94.33% of reproductive losses occur before 12 weeks of gestation. The proportion of primigravidas in the total number of reproductive losses is 6.78%, HIV-infected – 2.06%. Reproductive losses in the first pregnancy is associated with a gestational age of more than 12 weeks (OR 2.31, 95% CI 2.13–2.49), with HIV infection – less than 12 weeks (OR 3.59, 95% CI 2, 88–4.47). Tyumen region without AO is characterized by a greater association of reproductive losses in pregnancy up to 12 weeks with HIV infection in comparison with the Khanty-Mansiysk Autonomous Okrug – Yugra (KhMAO): OR 1.83, 95% CI 1.67–2.00; and Yamalo-Nenets Autonomous Okrug (YNAO): OR 7.68, 95% CI 6.01–9.81; from 12 to 22 weeks – with HIV infection compared with KhMAO (OR 1.93, 95% CI 1.20–3.09) and YNAO (OR 3.0, 95% CI 1.30–6, 95), with a first pregnancy compared with KhMAO (OR 1.26, 95% CI 1.07–1.48) and YNAO (OR 1.81, 95% CI 1.40–2.35). The greatest contrast was noted between Tyumen region and YNAO. More than 50% of reproductive losses in pregnancy before 12 weeks is due to medical abortion. In Tyumen region without autonomous regions, at more than 12 weeks of gestation, medical abortion competes in frequency with spontaneous abortion. Tyumen region without AO showed high achievements in the total overcoming of criminal abortion.Conclusion. On the example of Tyumen region, the non-universality of the intra-territorial structure of the Republic of Poland is shown. Artificial reproductive losses dominate over non-artificial ones. Intraterritorial differences in reproductive losses require taking into account, monitoring many risk factors, adapting measures for their prevention, preservation and restoration of reproductive health to them.
