Secondary infertility probably occurs more frequently than primary infertility, and is often experienced more dramatically.
Approximately 10 percent of women have trouble to get pregnant a second time. Afflicted couples delay treatment or perhaps even feel that “things just aren’t meant to be.”
It is possible that with the first delivery, a fallopian tube became blocked, or that the couple just no longer has sex quite as frequently. Also, a woman’s weight gain after the first child can be to blame. Fat cells tend to store hormone-like, inflammation-promoting substances in the body.
30 to 40 percent of women of advanced age live with an overproduction of male hormones (as determined by blood test), and one effect is the population of the ovaries with non-developed eggs (PCOS, as determined by ultrasonic diagnosis). An amassment of non-developed eggs is also often observed in cases of diabetes and insulin resistance.
In men, testicular damage or an unfavorable lifestyle since the first pregnancy can significantly lower sperm quality.
