Frozen vs fresh embryo transfer with endometriosis: which is better?

Often, a frozen embryo transfer (FET) is preferred for many patients with endometriosis because it lets us separate ovarian stimulation (when estrogen can be high) from the transfer cycle. That “pause” can matter if your symptoms flare with stimulation, if you have deep disease, or if your body needs time to calm pelvic inflammation before focusing on implantation. In contrast, a fresh transfer happens immediately after stimulation, which can be a tougher hormonal and inflammatory window for some endometriosis patients.

That said, “better” isn’t one-size-fits-all—your best strategy depends on whether endometriosis is the only fertility factor or whether there are additional issues (like sperm, tubal, ovulatory, or ovarian reserve concerns), plus your age, embryo quality, and how you respond to stimulation. Our team often frames the decision around maximizing cumulative chances over a series of attempts while protecting your quality of life along the way. If you’re deciding between fresh and frozen, reach out to schedule a consultation so we can review your history (including prior surgery, endometriomas, and symptoms) and coordinate a plan that fits your goals.
