Does recommending timed intercourse really help the infertile couple?

Abstract

Timed sexual intercourse is a frequently prescribed component in the treatment for infertile couples. This recommendation is based on a combination of intuition and data from studies often lacking in methodology. With increasingly sophisticated and expensive methods available to time coitus with the presumptive evidence of ovulation, such as the urinary LH kits, the already significant stress of timed intercourse is compounded by the expense of these timing modalities. There is a complete lack of data demonstrating an increased chance of pregnancy with use of such devices. Yet there is evidence that the stress of timed intercourse is a major problem for infertile couples and may even hinder normal reproductive functioning. Available data suggest that much of the period of peak fertility during the menstrual cycle is missed if coitus is timed with the menstrual calendar, basal body temperature thermometer, or LH kit. In addition, the recommendation of a coital frequency of at least a couple of times per week would not only help reduce stress, but also ensure coitus during the period of the menstrual cycle with the greatest chance of resulting in a pregnancy.
