ASA 81 mg vs 162 mg During Frozen Embryo Transfer (FET)

Start date: November 1, 2023
Phase:
Study type: Observational

The use of low dose aspirin is recommended for high risk patients to reduce the risk of pre-eclampsia, placental abruption and antepartum hemorrhage. Recent studies have shown that in a specific population, the use of low dose aspirin might reduce the risk of preterm birth in pregnant women with singleton pregnancy. In June 2022, clinique ovo started implementing the use of Aspirin 162 mg instead of 81 mg in the frozen embryo transfer cycles based on recent study outcomes. The use of Aspirin 162 mg might have additional benefits on the embryo transfer outcomes by decreasing the miscarriage. Moreover this can be continued until late in pregnancy without adverse effects.

Natural Frozen Embryo Transfer (FET) vs Substituted Frozen Embryo Transfer (FET)

Start date: September 19, 2023
Phase:
Study type: Observational

In frozen embryo transfer substituted cycles, patients are treated with progesterone and estrogen in an attempt to mimic the natural cycle and a transfer is planned whenever the endometrium is ready. In contrast, in frozen embryo transfer natural cycle patients are not taking any hormones, only triggered with hCG (human chorionic gonadotropin) when a dominant follicle is ready or they wait for the disappearance of the dominant follicle to plan the transfer date. Some doctors and centres shift towards using the substituted protocol in an attempt to make scheduling easier with less frequent ultrasounds. This study will aim to compare clinical and biochemical pregnancy rates in patients who underwent frozen embryo transfers in natural cycles vs substituted cycles at the centre.

Strategies for Pregnancy Achievement

SPA
Start date: May 21, 2017
Phase: N/A
Study type: Interventional

The purpose of pilot study application is to build on the investigators' previous work that established the prospective association between stress and infertility. Specifically, the investigators hope to collect the preliminary data necessary to make them competitive to submit a R01 application to NIH for funding of a full-scale randomized controlled trial of an internet-based stress management program to examine its efficacy in decreasing stress and increasing pregnancy rates among women who have tried to get pregnant for 6-12 months without success. The program called Stress Free Now (SFN) was developed at the Cleveland Clinic and has been shown to be effective in lowering stress in a variety of populations. The program introduces concepts of mindfulness and cognitive-behavioral therapy to assist individuals in managing their stress levels. The intervention includes Internet-based interaction, daily emails and recommended relaxation practice of at least four days per week. Using targeted Facebook Ads and other recruitment modalities, the investigators will randomize 40 women ages 18-34 who have been trying to conceive for 6-12 months without success. The PI has been enrolling women in a similar study using this mechanism and has found it to be an efficient and cost-effective method of identifying potentially eligible individuals. Women will be randomized to SFN or a wait list control condition and will be followed for up to three months post-randomization with weekly journals as they try to conceive. The primary outcome of this randomized controlled trial is stress level, as measured by salivary alpha-amylase, while the secondary outcome will be pregnancy rate at the end of the three-month follow-up period.
