Initially, the oocytes were provided by one of the patient's consanguineous sisters. Then, the oocytes were obtained from another patient treated with assisted reproduction techniques (ART). Presently, oocytes thus produced are cryopreserved for at least 6 months before transfer.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The records from all women treated with ART at First Affiliated Hospital of Zhengzhou University since 2001 were reviewed and the pregnancy rates and clinical outcomes were determined for each of the 3 periods.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In the second period, the mean implantation and clinical pregnancy rates were significantly higher for the 22 oocyte recipients than for their donors.

There were 40 live births for 32 of the recipients over 28 cycles, and the rates of implantation and clinical pregnancy were much higher for the recipients than for the other ART patients (<jats:italic>P<\/jats:italic> &lt; 0.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Using freshly donated eggs yields a higher pregnancy rate but there is a risk of infectious disease.
