Introduction and objective:
Endometriosis is defined as the presence of endometrium-like tissue outside the uterine cavity which can cause chronic pelvic pain, dysmenorrhea, infertility, and obstetric complications. The study was undertaken to elucidate the influence of endometriosis on conception, pregnancy and course of Latour, as well as outcomes for the growth of the foetus.

Material and methods:
A single centre study was undertaken of endometriosis patients who were followed-up for five years after laparoscopy. The study group consisted of 30 patients with endometriosis who conceived, of whom 120 underwent laparoskopy. The control group consisted of 30 healthy women who delivered children and were hospitalized in a two-month period in 2015. Each patient completed a questionnaire regarding endometriosis symptoms, infertility duration, gravidity, smoking habits, education, metod of conception, incidence of pre-term labour, foetal growth restriction (FGR), small for gestational age (SGA) and pregnancy-induced hypertension (PIH). Analysis of the data was carried out using STATISTICA v.10.

A significant difference was observed in maternal age (34.7 ±4.7 for the study group vs. 29.8±4.9 years for the control group; p=0.001). In the study group, an increased incidence of caesarean section was noted (OR 4.9; 95% CI 1.61–15.07). No significant differences were observed in the incidence of preterm labour, FGR, SGA and PIH.

Delivering child at older age was observed in the endometriosis group, compared with controls, which suggests that endometriosis extends the time to conceiving. Higher maternal age at delivery and prolonged time to pregnancy may be the factors that influence the rate of caesarean section in endometriosis patients.

The authoirs extend their special thanks to dr Tomasz Wierzbowski who performed laparoscopies in ednometriosis patients in 2010–2011.
