          Abstract

          Resumen: OBJETIVO: Evaluar la relación entre la cuenta folicular antral y la hormona antimülleriana con la cantidad de ovocitos recuperados y la tasa de nacido vivo. MATERIALES Y MÉTODOS: Estudio retrospectivo, observacional, descriptivo y comparativo efectuado en pacientes atendidas en un hospital de tercer nivel. Parámetros de estudio: ciclos FIVTE-ICSI practicados entre enero de 2017 y marzo de 2021. Los ciclos, para fines de estudio, se dividieron en tres grupos: 1) cuenta folicular antral, 2) hormona antimülleriana y 3) ambos parámetros alterados. Para evaluar la relación de los marcadores con la cantidad de ovocitos recuperados y la tasa de nacido vivo se llevó a cabo un análisis estadístico exploratorio. Entre los tres grupos se compararon las características sociodemográficas y clínicas mediante las pruebas de Kruskal-Wallis y χ2, para variables continuas y categóricas, respectivamente. Se consideró significativo un nivel menor de 0.50; se utilizó el programa estadístico STATA 12. RESULTADOS: Entre los tres grupos analizados se incluyeron 222 ciclos: con cuenta folicular antral, hormona antimülleriana o ambos alterados. Se encontraron 54 (24.3%) con un nacido vivo. La cantidad de folículos antrales y la tasa de nacido vivo fueron significativamente menores en las pacientes con ambos marcadores alterados. Las pacientes con concentraciones alteradas de hormona antimülleriana tuvieron mejor pronóstico (RM 2.3; IC95%: 1.08-4.93, p < 0.03). La dosis de FSH y la cantidad de embriones transferidos fueron las variables que influyeron en la probabilidad de tener un recién nacido vivo. CONCLUSIONES: La concentración de hormona antimülleriana menor de 1.2 ng/mL se relaciona con mejor respuesta ovárica y mayor tasa de nacido vivo. Esta mayor probabilidad está influida por la cantidad de gonadotropinas utilizada y de embriones transferidos.

          Abstract: OBJECTIVE: To evaluate the relationship between antral follicular count and antimüllerian hormone with the number of oocytes retrieved and live birth rate. MATERIALS AND METHODS: Retrospective, observational, descriptive and comparative study carried out in patients attended at a tertiary level hospital. Study parameters: IVF-ICSI cycles performed between January 2017 and March 2021. The cycles, for study purposes, were divided into three groups: 1) antral follicular count, 2) antimüllerian hormone and 3) both parameters altered. To evaluate the relationship of the markers with the number of oocytes recovered and the live birth rate, an exploratory statistical analysis was performed. Sociodemographic and clinical characteristics were compared between the three groups using Kruskal-Wallis and 2 tests for continuous and categorical variables, respectively. A level of less than 0.50 was considered significant; STATA 12 statistical software was used. RESULTS: Among the three groups analyzed, 222 cycles were included: with antral follicular count, antimüllerian hormone or both altered. Fifty-four (24.3%) were found with a live birth. The number of antral follicles and live birth rate were significantly lower in patients with both markers altered. Patients with altered antimüllerian hormone concentrations had better prognosis (MR 2.3; 95%CI: 1.08-4.93, p < 0.03). FSH dose and number of embryos transferred were the variables that influenced the probability of having a live newborn. CONCLUSIONS: Antimüllerian hormone concentration less than 1.2 ng/mL is related to better ovarian response and higher live birth rate. This higher probability is influenced by the number of gonadotropins used and embryos transferred.

          Association between the number of eggs and live birth in IVF treatment: an analysis of 400 135 treatment cycles.

          While live birth is the principal clinical outcome following in vitro fertilization (IVF) treatment, the number of eggs retrieved following ovarian stimulation is often used as a surrogate outcome in clinical practice and research. The aim of this study was to explore the association between egg number and live birth following IVF treatment and identify the number of eggs that would optimize the IVF outcome. Anonymized data on all IVF cycles performed in the UK from April 1991 to June 2008 were obtained from the Human Fertilization and Embryology Authority (HFEA). We analysed data from 400 135 IVF cycles. A logistic model was fitted to predict live birth using fractional polynomials to handle the number of eggs as a continuous independent variable. The prediction model, which was validated on a separate HFEA data set, allowed the estimation of the probability of live birth for a given number of eggs, stratified by age group. We produced a nomogram to predict the live birth rate (LBR) following IVF based on the number of eggs and the age of the female. The median number of eggs retrieved per cycle was 9 [inter-quartile range (IQR) 6-13]. The overall LBR was 21.3% per fresh IVF cycle. There was a strong association between the number of eggs and LBR; LBR rose with an increasing number of eggs up to ∼15, plateaued between 15 and 20 eggs and steadily declined beyond 20 eggs. During 2006-2007, the predicted LBR for women with 15 eggs retrieved in age groups 18-34, 35-37, 38-39 and 40 years and over was 40, 36, 27 and 16%, respectively. There was a steady increase in the LBR per egg retrieved over time since 1991. The relationship between the number of eggs and live birth, across all female age groups, suggests that the number of eggs in IVF is a robust surrogate outcome for clinical success. The results showed a non-linear relationship between the number of eggs and LBR following IVF treatment. The number of eggs to maximize the LBR is ∼15.

            Correlation of ovarian reserve tests with histologically determined primordial follicle number.

            To investigate the relationship between clinical markers of ovarian reserve and the true ovarian reserve as determined by the ovarian primordial follicle number. Prospective investigation. Academic medical center. Forty-two healthy women (aged 26-52 years) undergoing oophorectomy for benign gynecologic indications. Transvaginal ultrasound examination for the determination of the ovarian antral follicle count (AFC) and serum measurements of clinical markers of ovarian reserve. All measurements were obtained within 2 weeks of surgery, irrespective of cycle day. Ovarian primordial follicle count was then determined using a validated fractionator/optical disector method. Univariate and partial correlations between ovarian reserve markers and ovarian primordial follicle count. There were significant correlations between the ovarian primordial follicle count and AFC (r=0.78), anti-Müllerian hormone (AMH; r=0.72), FSH (r=-0.32), inhibin B (r=0.40), and chronological age (r=-0.80). After adjusting for age, significant correlations were identified between the ovarian primordial follicle count and AFC (r=0.53) and AMH (r=0.48). The ovarian AFC and serum levels of AMH correlate with the ovarian primordial follicle number even after adjustment for chronological age. Copyright © 2011 American Society for Reproductive Medicine.
