In a prospective comparison of IP, IUI, and natural intercourse following superovulation in couples diagnosed as having unexplained infertility, semen factors, or sperm antibodies, pregnancy rates were found to be significantly higher after IP. Pregnancy rates were also higher in the unexplained infertility group when compared with those with semen factors. It was concluded that IP in combination with superovulation offered a simple, inexpensive, safe alternative to GIFT.
在一项针对被诊断为不明原因不孕、精液因素或精子抗体的夫妇进行超排卵后宫腔内人工授精（IP）、宫腔内人工授精（IUI）和自然性交的前瞻性比较中，发现IP后的妊娠率显著更高。与精液因素患者相比，不明原因不孕组的妊娠率也更高。得出的结论是，IP联合超排卵为配子输卵管内移植（GIFT）提供了一种简单、廉价、安全的替代方法。
