Levonorgestrel hormone releasing intrauterine system (Mirena) as a contraceptive in egg donors: case report.

We report the safe use of levonorgestrel hormone releasing intra uterine system (Mirena) as a contraceptive in egg donors during a treatment cycle. In the first case report, a 29-year-old egg donor using the Mirena coil for contraception and two egg recipients, aged 41 years and 32 years respectively underwent standard IVF treatment, oocyte retrieval in the egg donor and in vitro fertilization followed by embryo transfer in the recipient. The outcome of IVF cycle using donor eggs was satisfactory with successful pregnancy in the egg recipient. The second case involved a 34-year-old egg donor using the Mirena coil and a 44-year-old recipient. Our findings suggest that egg donors can safely use the (Mirena) as a contraceptive device during treatment, without compromising follicular development and oocyte quality.
