‘Why can’t I get pregnant this time around?’ is a bugging question couples with secondary infertility often ask.
Well, here are a few other reasons you might consider:
Age: Fertility naturally declines as age decreases.
New Partner: Your new partner might have an undiagnosed infertility problem.
Worsened underlying fertility problem: You might have had endometriosis, subclinical PCOS or maybe your ovarian reserves were already decreasing. These issues might lead to a worsened fertility problem.
Weight Gain: This may lead to ovulation problems in women, and possibly impact sperm health in men.
Fertility Problem from Previous Pregnancy: Child birth may cause a pelvic infection or multiple D&C procedures may cause uterine adhesions or blocked fallopian tubes. Also, having a C-section, can cause a scarred tissue, which can impact fertility too.
