There’s no need to panic quite yet. Infertility is generally defined as the inability to conceive after one year of regular, unprotected intercourse. If you are otherwise healthy it may just be taking a little longer than you originally expected to conceive. If you are experiencing problems with ejaculation or erection, have had undescended testes, varicoceles or damage to the testes you might consider seeing your GP. Also remember it takes two to make a baby, so make sure your partner is checked out too if you suspect there is a problem.
