1 Delayed ovulation may be a sign of poor egg quality. 2  Even if fertilization occurs, with delayed ovulation the endomtrium (uterine lining) has aged since the beginning of your cycle and may no longer be ready for the implantation of the fertilized egg.
Studies show that couples who time sex to coincide with ovulation get pregnant faster. (The best time to have sex is during the two days before ovulation and on the day you ovulate.) In one study, the pregnancy rates of couples who timed intercourse with ovulation were higher than typically seen among couples trying to conceive: 1  38 percent were pregnant after one cycle (up from 30 percent). 2  68 percent were pregnant after three cycles (up from 60 percent). 3  81 percent were pregnant after six cycles (up from 80 percent).
