Purpose To evaluate the cystectomy-induced damage on the follicular growth and ovulation of an affected ovary during natural cycles. Methods Twenty-eight infertile patients with unilateral ovarian endometriomas who underwent laparoscopic cystectomy were retrospectively evaluated. The ovulation rate of an affected ovary during natural cycles was compared before and after cystectomy in each patient, and it was also determined if ovulation from the affected ovaries resulted in pregnancy.Results After surgery, the ovulation rate was significantly lower than that before cystectomy (16.9±4.5% vs. 34.4± 6.6%, P= 0.013). After surgery, 14 pregnancies were achieved without IVF treatment, and only 2 of them (14.3%) were achieved from an operated-side ovary. However, the pregnancy rate per ovulatory cycle of the operated-side ovary was not different from that of the intact ovary (8.8% vs. 5.8%, P=0.750). Conclusions Laparoscopic cystectomy is an invasive treatment in that it reduces the frequency of ovulation; however the pregnancy rate per ovulation did not deteriorate.
Laparoscopic proximal tubal division preserved ovarian function and was an optimal operation method for infertility patients with hydrosalpinges. The basal FSH values after laparoscopic proximal tubal division were comparable to those before surgery.
PurposeThe purpose of this study was to compare the sizes of the placenta and umbilical cord in women with natural pregnancy versus those undergoing in vitro fertilization (IVF).MethodsOverall, 1610 cases of uncomplicated single pregnancies with vaginal delivery at ≥ 37 weeks of gestation were included in this study. The patients were divided into two groups: natural pregnancy group (n = 1453) and IVF pregnancy not including intracytoplasmic sperm injection (ICSI) treatment (n = 157). The groups were compared in terms of gestational week, maternal age, parity, maternal weight gain, prepregnancy maternal BMI, infant weight at birth, infant head circumference, placental weight, cross section of the placenta, cross section of the umbilical cord, insertion site of the umbilical cord, and umbilical cord length. Stepwise selection and multivariate logistic regression were used for statistical analysis to correct the result as an independent factor.ResultsThere was no difference in the size of the placenta and umbilical cord between women with natural pregnancy and with IVF, but the incidence of velamentous insertion of the cord was significantly increased in women with IVF pregnancy (adjusted odd ratio [AOR] 1.72, 95% confidence interval [CI] 1.08–2.72, p = 0.026).ConclusionsAlthough there is no difference in placental weight and cord size, velamentous insertion of the umbilical cord increases in IVF pregnancy and needs careful observation during the delivery process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
