Objective:
The duration of progesterone exposure is critical for establishing and maintaining a pregnancy in hormone replacement treatment (HRT)–frozen embryo transfer (FET) cycles. This study compared the live birth rates (LBRs) of patients undergoing day-6 warmed blastocyst transfer on either the 6th or 7th day of progesterone administration in HRT-FET cycles.
Methods:
A retrospective cohort study was conducted using data from the central registry of Indira IVF Hospital Private Limited. In total, 2,633 patients who underwent day-6 blastocyst transfer cycles with HRT-FET were identified. The cycles were categorized based on the timing of the day-6 blastocysts transfer: P+6 vs. P+7 (initiation date: P+1). Propensity scores were calculated. The primary outcome measure was the LBR.
Results:
Following propensity score matching, a total of 1,401 patients were included in the final analysis (P+6: n=1,212; P+7: n=189). The number of previous attempts was significantly higher in the P+6 group, whereas the rate of preimplantation genetic testing for aneuploidy was significantly higher in the P+7 group. The LBRs were 59.2% and 54.5% in the P+6 and P+7 groups, respectively (p=0.21). Multivariate regression analysis revealed that the number of previous in vitro fertilization attempts (odds ratio [OR], 3.246; 95% confidence interval [CI], 2.429 to 4.337; p<0.001), the number of blastocysts transferred (OR, 2.011; 95% CI, 1.461 to 2.768; p<0.01), and endometrial thickness on the day of progesterone initiation (OR, 1.143; 95% CI, 1.022 to 1.28; p=0.02) were independent predictors of live birth.
Conclusions
The LBRs were comparable in patients who underwent day-6 warmed blastocyst transfer on day 6 or 7 post-progesterone initiation in HRT-FET cycles.

Broad ligament pregnancy is defined as gestation that grows in the space formed by anterior and posterior peritoneal folds of the broad ligament. We report a case of 30 years old lady admitted to our hospital with the diagnosis of gravida 2, para 1, live birth 1, with 24 weeks of gestation with low lying placenta with anhydramnios. She was taken up for lower segment cesarian section at 28 weeks gestation in view of low lying placenta with chorioamnionitis. The broad ligament pregnancy was diagnosed peroperatively after identifying the anatomical relationship of the pregnancy. Sac was excised and margins secured after extraction of the baby and placenta. Patient had an uneventful postoperative period. Broad ligament pregnancy may be missed in antenatal period but in cases of displaced cervix, early onset unexplained anhydramnios, and failed induction of labor, it may raise high suspicion. Laparotomy/laparoscopic management is the mainstay of management of broad ligament pregnancy.
