AI Article Synopsis
- The study assessed how luteal phase support impacts clinical pregnancy and live birth rates after ovulation induction and IUI.
- A total of 579 cycles were analyzed, where 451 received progesterone support and 128 did not.
- Results showed that luteal phase support significantly increased clinical pregnancy (20.6% vs. 9.4%) and live birth rates (14% vs. 7%), with both progesterone methods providing similar outcomes.
Article Abstract
Objective: This study aimed to evaluate the effect of luteal phase support on clinical pregnancy and live birth rates after ovulation induction and intrauterine insemination (IUI).
Methods: 579 cycles from 2010 to 2013 were retrospectively evaluated. Ovarian stimulation was performed with gonadotropins, and rHCG was used for ovulation triggering. All patients received IUI. 451 cycles were supported by receiving vaginal micronized progesterone capsules (142 cycles) or vaginal progesterone gel (309 cycles) whereas 128 cycles were not supported.
Results: Clinical pregnancy (20.6 versus 9.4%; p = 0.004) and live birth rates (14 versus 7%; p = 0.036) were higher for supported group than for unsupported group. Progesterone gel and micronized progesterone subgroups achieved similar clinical pregnancy and live birth rates (21.4 versus 19%, p = 0.567 and 14.2 versus 13.4%, p = 0.807; respectively).
Conclusions: Luteal phase support improved the success of IUI cycles affecting both clinical pregnancy and live birth rates when gonadotropins were used for ovulation induction. The use of vaginal progesterone gel or micronized progesterone significantly improves clinical pregnancy rates. The live birth rates were higher in the progesterone gel group, but were similar in the micronized progesterone group compared to the unsupported group.

Reproductive Medicine, Instituto Bernabeu of Fertility and Gynaecology.
The research question is as follows: Are estrogen and progesterone receptor genotypes associated with thin endometrium? We performed a prospective cohort study of 129 patients who underwent preimplantation genetic testing for aneuploidies. These patients were categorized according to endometrial thickness: >7 mm control group (n = 94) and ≤7 mm study group (n = 35). Polymorphisms in the genes ESR1 (rs9340799 and rs3138774), ESR2 (rs1256049 and rs4986938), and PGR (rs1042838) were analyzed.
