OBJECTIVE
We determined the prognostic value of the postcoital test in subfertile couples.
STUDY DESIGN
A retrospective study relates the result of the postcoital test to the occurrence of a spontaneous pregnancy. In a fertility center of a university hospital, data from the complete fertility workup of 956 couples who were examined because of infertility due to cervical hostility, male subfertility, or unexplained causes were collected. Statistical analysis was done with Cox regression.
RESULTS
The postcoital test result 9 to 12 hours after intercourse is strongly associated with future pregnancy during the first year after intake; the association is also present when the relation with other prognostic variables is taken into account.
CONCLUSIONS
The postcoital test result is a strong predictor of possible fertility within the following year.
目的
我们确定了性交后试验对不育夫妇的预后价值。
研究设计
一项回顾性研究将性交后试验结果与自然妊娠的发生情况相关联。在一家大学医院的生育中心，收集了956对因宫颈因素、男性不育或不明原因导致不孕而接受检查的夫妇的完整生育检查数据。采用Cox回归进行统计分析。
结果
性交后9至12小时的性交后试验结果与入组后第一年内未来妊娠密切相关；在考虑与其他预后变量的关系时，这种关联也存在。
结论
性交后试验结果是次年可能生育能力的有力预测指标。
