Secondary infertility: Why does it happen?
Secondary infertility is the inability to become pregnant or to carry a baby to term after previously giving birth to a baby. Secondary infertility shares many of the same causes of primary infertility.
Secondary infertility might be caused by:
-Impaired sperm production, function or delivery in men
-Fallopian tube damage, ovulation disorders, endometriosis and uterine conditions in women
-Complications related to prior pregnancy or surgery
-Risk factor changes for you or your partner, such as age, weight and use of certain medications
I-f you’re younger than 35 and have frequent, unprotected sex but don’t become pregnant after a year, talk to your health care provider. If you’re 35 or older — or you have other infertility risk factors such as infrequent periods or endometriosis — earlier evaluation is recommended.
