Whatever the mechanism of such improvements may be, the results in this study point out that coitus interruptus in the human may not be the method of choice for collection of semen specimens, especially in patients with spermatogenic dysfunctions such as hypospermia, oligospermia, and asthenospermia. It should also be noted at this point that, for whatever purpose (semen analysis or artificial insemination by husband), the collected specimen should as closely as possible resemble the ejaculate delivered during intercourse. The complete coitus method, as applied in this study, showed that completion of the ejaculatory process during intercourse as compared with the coitus interruptus method, may assist in the improvement of the collected specimen and should closely resemble the ejaculate obtained during intercourse without the use of Silastic condoms. Furthermore, on the basis of the results generated in this study, the complete coitus method should always be the method of choice for male infertility patients with ejaculatory and spermatogenic dysfunctions as well as for scientists and clinicians who deal in the field of infertility diagnosis and treatment.
无论这种改善的机制是什么，本研究结果指出，体外射精可能不是人类采集精液标本的首选方法，尤其是对于患有精子发生功能障碍（如精子过少、少精子症和弱精子症）的患者。此时还应注意，无论出于何种目的（精液分析或丈夫人工授精），所采集的标本应尽可能与性交时射出的精液相似。本研究采用的完全性交法表明，与体外射精法相比，性交过程中射精过程的完成可能有助于改善所采集的标本，并且应与不使用硅橡胶避孕套性交时获得的精液非常相似。此外，基于本研究产生的结果，完全性交法应始终是患有射精和精子发生功能障碍的男性不育患者以及从事不孕症诊断和治疗领域的科学家和临床医生的首选方法。
