RESUMO

OBJECTIVE: To compare the proportion of women achieving a desired ovarian response following ovarian stimulation when gonadotropin dosing was determined based on antral follicle count (AFC) vs serum anti-Müllerian hormone (AMH) level, in women undergoing in-vitro fertilization (IVF) using the gonadotropin-releasing hormone (GnRH) antagonist protocol. METHODS: This was a randomized double-blind trial carried out in a university-affiliated assisted reproduction unit. A total of 200 women undergoing their first IVF cycle using the GnRH-antagonist protocol between April 2016 and February 2018 were randomized to determination of gonadotropin dosing based on either AFC or serum AMH level measured in the pretreatment cycle 1 month before the IVF cycle. Patients underwent IVF as per our center's standard protocol. The proportion of subjects achieving a desired ovarian response, defined as retrieval of six to 14 oocytes, was compared between the two study arms. Subgroup analysis of patients with baseline AFC > 5 and those with baseline AFC ≤ 5 was performed. Concordance in AFC and AMH categorization between the pretreatment cycle and the ovarian-stimulation cycle was assessed using Cohen's kappa (κ). RESULTS: There was no significant difference in the proportion of patients achieving a desired ovarian response between the AFC (54%) and AMH (49%) groups (P = 0.479). The median number of oocytes retrieved was nine vs seven (P = 0.070), and the median follicular output rate was 0.54 vs 0.55 (P = 0.764) in the AFC and AMH groups, respectively. Similar findings were observed on subgroup analysis of subjects with AFC ≤ 5 and AFC > 5 at the start of ovarian stimulation (P > 0.05 for all comparisons). There was moderate concordance between AFC and AMH measured in the pretreatment cycle and the stimulation cycle (κ = 0.478 and 0.587, respectively). CONCLUSION: The proportion of women achieving a desired ovarian response following ovarian stimulation using the GnRH-antagonist protocol is similar when the gonadotropin-dosing algorithm used is based on AFC or serum AMH level.

Comparación del recuento de folículos sinusales y el nivel de la hormona antimulleriana en el suero para la determinación de la dosis de gonadotrofina en la fecundación in vitro: ensayo aleatorizado OBJETIVO: Comparar la proporción de mujeres que logran una respuesta ovárica deseada tras la estimulación del ovario cuando se determinó la dosis de gonadotrofina en función del recuento de folículos sinusales (AFC, por sus siglas en inglés) frente al nivel de la hormona antimulleriana (HAM) en el suero, en mujeres que se sometieron a una fecundación in vitro (FIV) mediante el protocolo de antagonistas de la hormona liberadora de gonadotropina (GnRH, por sus siglas en inglés). MÉTODOS: Se trata de un ensayo aleatorizado doble ciego realizado en una unidad de reproducción asistida afiliada a una universidad. Un total de 200 mujeres que se sometieron a su primer ciclo de FIV y utilizaron el protocolo de antagonistas de la GnRH entre abril de 2016 y febrero de 2018 fueron asignadas al azar a la determinación de la dosis de gonadotrofina basada en el nivel de AFC o de HAM en suero, medidos en el ciclo de pretratamiento un mes antes del ciclo de FIV. Las pacientes se sometieron a una FIV según el protocolo estándar de nuestro centro. La proporción de mujeres que lograron una respuesta ovárica deseada, definida como la recuperación de seis a 14 ovocitos, se comparó entre las dos ramas del estudio. Se realizó un análisis de subgrupos de las pacientes con AFC de base >5 y de aquellas con AFC de base ≤5. La concordancia en la categorización del AFC y la HAM entre el ciclo de pretratamiento y el ciclo de estimulación ovárica se evaluó utilizando la medida estadística kappa de Cohen (κ). RESULTADOS: No hubo diferencias significativas en la proporción de pacientes que lograron una respuesta ovárica deseada entre los grupos de AFC (54%) y HAM (49%) (P=0,479). La mediana del número de ovocitos recuperados fue de nueve frente a siete (P=0,070), y la mediana de la tasa de producción folicular fue de 0,54 frente a 0,55 (P=0,764) en los grupos AFC y HAM, respectivamente. Se observaron hallazgos similares en el análisis de subgrupos de pacientes con AFC ≤5 y AFC >5 al comienzo de la estimulación ovárica (P>0,05 para todas las comparaciones). Se observó una concordancia moderada entre el AFC y la HAM medidos en el ciclo de pretratamiento y el ciclo de estimulación (κ=0,478 y 0,587, respectivamente). CONCLUSIÓN: La proporción de mujeres que logran una respuesta ovárica deseada después de la estimulación ovárica utilizando el protocolo de antagonistas de la GnRH es similar cuando el algoritmo de dosificación de gonadotrofina utilizado se basa en el nivel del AFC o de la HAM en suero.

RESUMO

OBJECTIVES: To evaluate the efficacy of topical lidocaine gel and intrauterine lidocaine infusion administered prior to saline contrast sonohysterography (SCSH) in reducing pain level during the procedure. METHODS: This was a randomized, double-blind, placebo controlled trial. We recruited 120 women scheduled to undergo SCSH and randomized them into one of three groups according to administration of gel and intrauterine infusion immediately prior to the procedure: (1) the 'lidocaine gel' group received 3 mL 2% lidocaine gel applied to the cervix and intrauterine infusion, using an infant feeding tube without balloon, of 5 mL normal saline; (2) the 'lidocaine infusion' group received 3 mL gel lubricant applied to the cervix and intrauterine infusion of 5 mL 2% lidocaine; (3) the placebo group received 3 mL gel lubricant applied to the cervix and intrauterine infusion of 5 mL normal saline. The tube was left in place for the SCSH procedure. The primary outcome measure was the overall pain level (on a scale of 0-100) reported by the women during the SCSH procedure. Women also rated their pain levels at various other time points and an observer assessed visible signs of the women's discomfort during the procedure, producing a distress score. RESULTS: There were no significant differences among the three groups in baseline characteristics, volume of saline solution infused, tenaculum use and duration and difficulty level of the SCSH procedure. The median (range) pain scores during normal saline infusion for the SCSH procedure were 0 (0-65) in the placebo group, 2.5 (0-80) in the lidocaine gel group, and 0 (0-70) in the lidocaine infusion group. The pain scores at other time points, the overall pain score and the distress score were also comparable for the three groups. No significant adverse events were reported. CONCLUSIONS: SCSH performed with an infant feeding tube without balloon is associated with very low pain levels. Topical lidocaine gel application and intrauterine lidocaine infusion do not further reduce pain levels during SCSH.

RESUMO

OBJECTIVE: To assess the relationship between endometrial/subendometrial vascularity and the risk of pregnancy-induced hypertension (PIH) or small-for-gestational-age (SGA) fetuses in women who had a live birth following in-vitro fertilization (IVF). METHODS: This was a retrospective study of women who had a live birth after IVF from November 2002 to December 2004. Only women with a singleton pregnancy (n = 104) were included for analysis. Three-dimensional ultrasound measurement with power Doppler of the endometrial and subendometrial regions was performed on the day of oocyte retrieval in stimulated IVF cycles or on luteinizing hormone surge + 1 day in frozen-thawed embryo transfer cycles to measure the endometrial volume and the vascularization index (VI), flow index (FI) and vascularization flow index (VFI) of the endometrial and subendometrial regions. Pregnancy outcomes were also reviewed. RESULTS: Eight women (7.7%) had PIH or an SGA fetus. Women in the PIH/SGA group had significantly lower endometrial VI (0.504 vs 1.051; P = 0.023) and VFI (0.121 vs 0.253; P = 0.023) than those in the non-PIH/SGA group. However endometrial FI was significantly higher in the PIH/SGA group (23.04 vs 22.71; P = 0.028). There were no significant differences in subendometrial indices between the two groups. CONCLUSION: Women who had a live birth following IVF and whose pregnancy was complicated by PIH or an SGA fetus had significantly lower endometrial vascularity in terms of VI and VFI than did women without PIH or SGA.
