Physicians who counsel women for preconception concerns are in an excellent position to give advice to couples regarding the optimal timing of intercourse to achieve pregnancy. The currently available evidence suggests that methods that prospectively identify the window of fertility are likely to be more effective for optimally timing intercourse than calendar calculations or basal body temperature. There are several promising methods with good scientific bases to identify the fertile window prospectively. These include fertility charting of vaginal discharge and a commercially available fertility monitor. These methods identify the occurrence of ovulation clinically and also identify a longer window of fertility than urinary luteinizing hormone kits. Prospectively identifying the full window of fertility may lead to higher rates of conception. Proper information given early in the course of trying to achieve pregnancy is likely to reduce time to conception for many couples, and also to reduce unnecessary intervention and cost.
为有孕前担忧的女性提供咨询的医生，非常适合就实现怀孕的最佳性交时机向夫妇提供建议。目前可得的证据表明，前瞻性确定生育窗口的方法，在优化性交时机方面可能比日历计算法或基础体温法更有效。有几种有前景且有良好科学依据的方法可用于前瞻性地确定生育窗口。这些方法包括阴道分泌物生育图表法和一种市面上可买到的生育监测仪。这些方法能从临床上确定排卵的发生，并且能确定比尿促黄体生成素检测试剂盒更长的生育窗口。前瞻性地确定整个生育窗口可能会提高受孕率。在尝试怀孕过程的早期提供恰当的信息，可能会减少许多夫妇的受孕时间，还能减少不必要的干预和费用。
