Abstract

ObjectiveTo determine whether treatment with combined pentoxifylline (PTX) and tocopherol (Vit.E) can improve uterine parameters in hormonal replacement therapy (HRT)-resistant women with premature ovarian failure (POF), for whom the outcome of assisted reproductive technology is usually negative. We previously reported that uterine radiation-induced fibrosis is reversible by combined PTX-Vit.E treatment.DesignCase report.SettingVolunteer participants in an oocyte donation (OD) program in a French public hospital.Patient(s)Three women with POF (ages 36 +/- 2 years) using HRT exhibited uterine hormonoresistance, although they had high E(2) plasma levels. Their mean endometrial thickness was 4.9 mm, and they had an echogenic endometrium and thin uterine crosses.Intervention(s)Between May 1998 and April 1999, treatment consisted of 800 mg of PTX combined with 1,000 IU of Vit.E daily for at least 9 months.Main outcome measure(s)Endometrial thickness, echogenicity, and pulsatility index of the uterine arteries, assessed by ultrasound and Doppler before and after treatment, and embryo implantation by IVF-OD.Result(s)PTX-Vit.E treatment was well tolerated and induced improvements, as mean edematous endometrial thickness increased to 7.4 mm, with nice uterine crosses. Three frozen-thawed ETs resulted in two viable pregnancies.Conclusion(s)In women with POF and uterine resistance to HRT, combined PTX-Vit.E reduces fibroatrophic uterine lesions and improves the uterine response to HRT, thus allowing embryo implantation and ongoing pregnancy.
