Secondary infertility is the inability to conceive after having conceived previously.
There are a number of things that can cause secondary infertility. After undergoing a vaginal delivery or C-section, there can be remnants from the previous pregnancy left in the uterus, which inhibit a new pregnancy from implanting. There can also be a piece of debris blocking the fallopian tubes or a post delivery endometritis can cause scarring of the fallopian tubes.
Age is probably the most common cause of secondary infertility. Fertility decreases with age regardless of previous pregnancy history. The most common cause of male secondary infertility is history of vasectomy. The evaluation of secondary infertility is the same as that for primary infertility which is to check a cycle day 3 FSH and estradiol level, Thyroid stimulating hormone level, prolactin level, hysterosalpingogram, sonohysterogram and a semen analysis for the men.
