In the remainder of this chapter, we look at some of the developments, experiences, and feelings involved in the physiological process of becoming parents, starting with becoming pregnant. This first step can be difficult for some couples.

Enhancing the Possibility of Conception

Choosing the right time for intercourse is important in increasing the probability of conception. Conception is most likely to occur within the 6-day period ending on the day of ovulation. It is difficult to predict the exact time of ovulation, but several meth­ods permit a reasonable approximation. Ovulation predictor tests, which measure the rise in luteinizing hormone (LH) in urine before ovulation, can accurately identify the best time for conception and can be purchased over the counter. Otherwise, the mucus method, body temperature, and the principles of the calendar method can also be used to estimate ovulation time, as discussed in Chapter 10. •

Some individuals and couples are interested in enhancing the possibility of conceiv­ing a child of a specific sex, as discussed in the following Sexuality and Diversity section.
