Antidepressants & TCC

My husband and I have been trying to get pregnant for 10 months now. We have a beautiful 2.5yr old and had a miscarriage last May. First time it took us 7mo the second time it took 2 months. The only thing that has changed is my husband started take an antidepressant last June. Has anybody conceived while taking an antidepressant? Does it affect sperm? Just looking for some insight.
