BackgroundThe impact of elevated estradiol on the day of human chorionic gonadotropin (hCG) administration on in vitro fertilization (IVF) outcomes has been debated for over 25 years. Some investigators have shown a positive effect, others a negative effect; while most have shown no effect. Few studies have expressed their findings based on live birth. This study examined the relationship between estradiol level and other IVF cycle response parameters in relation to pregnancy, with a focus on live births after controlling for embryo quality.MethodsWe performed a retrospective cohort study on 489 patients <40 years old that underwent an initial IVF cycle. Estradiol concentration on the day of hCG was categorized as; low <2000 pg/ml), mid (2001-4000 pg/ml) and high (>4000 pg/ml) to determine how estradiol level on the day of hCG affected response variables during the IVF cycle. We performed a subgroup analysis restricted to patients with good/fair quality embryos transferred (n = 428), to control for embryo quality and assessed pregnancy outcome. The association between estradiol and live birth (LB) was then evaluated after identifying and controlling for confounding factors. Multivariate analysis was used to identify significant main effects and interactions in the model. Estradiol levels were also compared in patients having a LB or not (NLB) in both populations.ResultsWe found that estradiol was significantly related to + hCG, clinical pregnancy rate, age, and most other IVF cycle response variables. After performing the subgroup analysis controlling for embryo quality, we found that LB rates were not different. Only the main effects of average embryo quality at transfer (AEQS), age and transferring two embryos influenced LB. Estradiol levels were also compared in patients having a LB or NLB in both populations and was found to be higher/not different in LB patients. LB rates and AEQS were also not different in a subgroup of patients having an elevated level of estradiol (>4200 pg/ml) on the day of hCG in patients having embryo transfer on day 3 or day 5.ConclusionsAfter controlling for embryo quality, elevated estradiol on the day of hCG had no effect on LB.

Although the bulking agent is most often found at 3- and 9-o'clock positions as intended, the distance from the UVJ is highly variable after an uncomplicated office-based transurethral injection. The bulking material does not form the characteristic spheres in 41% of cases and tracks toward the bladder neck or the distal urethra.

Since the first public health warning about vaginal mesh issued by the US Food and Drug Administration in 2008 and subsequent communications, removal of vaginal synthetic mesh has become increasingly common in tertiary health care centers.
