Summary

This trial will compare patients taking aspirin and heparin to those without to see if it improves results.

Who is the study for?
This trial is for women aged 18-42 who want to have a frozen embryo transfer, including those using donated embryos or eggs. It's open to patients with any history of IVF cycles. Women must not be currently pregnant, under 18, unable to consent in English, using a surrogate, or have certain medical conditions like bleeding disorders.
What is being tested?
The study is testing if Lovenox (a low-molecular weight heparin) combined with Aspirin can improve the success rates of thawed blastocyst transfers compared to standard protocols without these medications. Participants will be randomly assigned to either receive both drugs or none before their embryo transfer.
What are the potential side effects?
Possible side effects from Lovenox and Aspirin may include bleeding issues due to thinner blood, allergic reactions, and irritation at the injection site for Lovenox. The severity of side effects can vary among individuals.
