RESUMO

The present prospective cohort study evaluated the prevalence of FSH-R receptor Asn680Ser and Ala307Thr among infertile Indian women and the correlation of these polymorphisms with ART outcomes. Total 804 infertile and 209 fertile controls were enrolled for FSH-R analysis. Correlation of different genotypes with ovarian reserve markers, IVF parameters, and cumulative live birth rates (CLBR) was done among women undergoing IVF. In fertile controls, at 680 position GG (Ser/Ser) was the most common genotype; but among infertile women, all the genotypes were equally distributed. There was no significant difference in ovarian response parameters, oocyte yield, and CLBR among the three genotype groups. Empty follicle syndrome (EFS) was highest in women with AA or AG type at both positions. On categorisation of unexpected poor responders according to POSEIDON stratification; GG genotype at both positions had the lowest risk ratio of low-oocyte yield in ART cycles, but these differences were not statistically significant. This is the largest study from Indian ethnicity showing GG (Ser/Ser) genotype is most common among fertile women. The effect of FSH-R genotypes is very marginal on IVF parameters and is not reflected in CLBR. More prospective data may be required on the correlation of these genotypes with genuine EFS, thus stratifying the next cycles with self or donor oocytes. Routine genetic testing of FSH-R polymorphism should not be done except in a research setting. As both 680 and 307 positions are in linkage disequilibrium, only 680 position analysis may be done in a research setting.

RESUMO

Background: The purpose of the current study was to evaluate patient-oriented strategies encompassing individualized oocyte number (POSEIDON) criteria, validate stratification of low prognosis women, and prognosticate their reproductive potential in terms of cumulative live birth rate (CLBR) in Indian women. Methods: Out of 4048 women who underwent IVF/ICSI, 3287 women met the criteria for final evaluation of CLBR. They criteria were divided into (a) group 1a as cases with <4 oocytes retrieved and 1b with 4-9 oocytes retrieved; (b) group 2a as cases with <4 oocytes retrieved and 2b with 4-9 oocytes retrieved; (c) group 3 (<35 years, AMH <1.2 ng/ml, AFC <5); and (d) group 4 (≥35 years, AMH <1.2 ng/ml, AFC <5). Non-POSEIDON group was sub-divided into normo-responders (10-20 oocytes) and hyper-responder (>20 oocytes). Results: Overall CLBR was two-fold lower in POSEIDON group as compared to non-POSEIDON group (p<0.001). For every one-year increase in the age, the odds of CLBR decreased by 4% (OR 0.96, CI 0.93-0.99) in POSEIDON group and by 5% (OR 0.95, CI 0.92-0.98) in non-POSEIDON group. For every unit increase in number of oocytes retrieved, the odds of CLBR increased by 1.22 times (OR1.22, CI 1.16-1.28) in POSEIDON group and by 1.08 times (OR 1.08, CI 1.05-1.11) in non-POSEIDON group. Among POSEIDON groups, the highest values in CLBR belonged to group 1b followed by 3, 2b, 4, 1a, and 2a. Conclusion: POSEIDON stratification of low-prognosis women undergoing IVF may be considered valid to prognosticate and counsel women undergoing IVF. Prospective studies will strengthen its validity among different ethnic populations.

RESUMO

OBJECTIVE: To study donor and recipient factors affecting cumulative live birth rate (CLBR) in oocyte donor IVF (OD- IVF) cycles. METHODS: The present retrospective study was conducted at the ART center of a tertiary care referral hospital after ethical approval, and included all OD-IVF cycles done between January 2014 - October 2019. Donor parameters included age, body mass index (BMI), ovarian reserve markers, serum estradiol (E2) on trigger day, and number of total/grade 1 oocytes; recipient parameters included age and BMI. The primary outcome was CLBR resulting from one complete donor-recipient (D-R) cycle through fresh/frozen embryo transfer. Secondary outcomes included number of total and grade 1 oocytes, fertilization rate, cleavage rate and clinical pregnancy rate (CPR). RESULTS: We analyzed 262 D-R cycles for donor characteristics and 260 cycles for CLBR. The mean age of the recipients was 35.20±4.05, and for donors it was 25.29±2.03 years. The CPR and CLBR per started cycle was 60% and 55.7%, respectively. Recipient BMI and grade 1 oocytes were found to be independent predictors of CLBR in multivariate analysis. As the number of grade 1 oocytes increased, the likelihood of live births increased by 10% (95% CI, 1.04 - 1.32, p=0.008). Recipient BMI ≥25kg/m2 reduced the chances of CLBR by 50% (95% CI, 0.27 - 0.81, p=0.007). CONCLUSIONS: Number of grade 1 oocytes and recipient BMI significantly affect CLBR in OD-IVF cycles. Recipients with BMI ≥25kg/m² may be advised to lose weight and improve CLBR likelihood.

RESUMO

CONTEXT: Studies have found intrauterine perfusion of granulocyte colony-stimulating factor (G-CSF) to improve endometrial thickness and implantation rates in women undergoing in vitro fertilization (IVF). AIMS: To study the effect of intrauterine perfusion of G-CSF on endometrial parameters and IVF outcomes in patients undergoing fresh embryo transfers. SETTINGS AND DESIGN: This was a randomized double-blinded placebo-controlled trial conducted at assisted reproduction unit of a tertiary care center. SUBJECTS AND METHODS: One hundred and fifty patients undergoing IVF/intracytoplasmic sperm injection (ICSI) treatment and fresh embryo transfers were randomized to intervention and placebo groups. Patients in the intervention group received intrauterine perfusion of 300 µg (0.5 ml) of G-CSF on the day of ovulation trigger. Patients in placebo group received intrauterine perfusion of 0.5 ml normal saline on the day of ovulation trigger. The primary outcome measure was clinical pregnancy rate. The secondary outcome measures were change in endometrial thickness, volume, and vascularity on the day of embryo transfer; biochemical pregnancy rate, implantation rate, ongoing pregnancy rate, and live birth rate. Statistical analysis was carried out using STATA 12.0 (StataCorp LP, College Station, Texas, USA). RESULTS: Endometrial vascularity in the intervention group was significantly higher on the day of embryo transfer compared to the placebo group. Clinical pregnancy rate was 27.6% in the intervention group compared to 18.9% in the placebo group and the difference was not statistically significant (P = 0.207). There was no statistically significant difference between biochemical pregnancy rate, implantation rate, ongoing pregnancy rate, live birth rate and endometrial parameters between the two groups. CONCLUSIONS: Routine use of G-CSF in unselected IVF cycles may not lead to increase in positive IVF outcomes. More trials with larger sample sizes are required before approving or refuting the role of routine G-CSF in increasing IVF success rates. (CTRI/2017/10/010310).

RESUMO

AIMS AND OBJECTIVES: To evaluate the role of endometrial thickness, pattern and sub-endometrial blood flows measured by 2D power Doppler ultrasound to predict pregnancy during in-vitro fertilization (IVF) treatment. STUDY DESIGN: Prospective, non-randomized clinical study. MATERIALS AND METHODS: This was a prospective observational study. A total of 101 infertile women were recruited from our IVF-ET program from January to December, 2009. Women with tubal factor, male factor and unexplained infertility were included in the study. RESULTS: The mean age was 35 years and mean duration of infertility was 8 years. Seventy five (74.25%) patients had primary infertility and 26 (25.74%) had secondary infertility. The mean endometrial thickness was 8.1 mm and endometrial blood flow was in Zone I in 18 patients, 28 patients had blood flow in Zone II and 54 had in Zone III. Overall, 27 (26.73%) patients conceived and in these women the endometrial thickness was between 6 and 12 mm. CONCLUSIONS: With a thin endometrium (≤7 mm) and no-triple-line endometrial pattern coexisting in an in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) candidate, cryopreservation should be recommended. With a thin endometrium and a good texture (triple-line), other prognostic factors, such as embryo quality, should be taken into account. The endometrial vascularity has a useful predictive value on the implantation rate in IVF cycles irrespective of the morphological appearance of the endometrium. However, further study is needed to make a definitive conclusion.

RESUMO

OBJECTIVE: To evaluate the endometrial blood flow by two-dimensional power Doppler ultrasound as possible implantation markers and pregnancy predictors in women with and without genital tuberculosis undergoing in vitro fertilization-embryo transfer cycle (IVF-ET). METHODS: This was a prospective observational study. A total of 183 infertile women were recruited from our IVF-ET program from January to December 2009. Women with tubal factor, male factor and unexplained infertility were included in the study. RESULTS: The age, duration of infertility and BMI of the women were comparable in both the groups. The mean gonadotropin usage in Group 1 was 2,881.3 IU (±SD 949.7) and 3,077.8 (±SD 927.9) in Group 2. Total number of eggs obtained, duration (days) of stimulation, Estradiol (E2) concentration and endometrial thickness (in mm) showed no significant difference in the two groups. Even the peak systolic velocity, pulsatility index (PI) and resistance index (RI) was not statistically significant between the two groups. Pregnancy and implantation was higher in women with endometrial flow in zone 3 in both the groups though it did not reach any statistical significance. CONCLUSION: The present study showed no difference in endometrial blood flow and pregnancy rates in patients with or without genital tuberculosis.
