In my opinion, yes, provided there is no functional or structural defect. Consult your local homeopathic physician.
In my opinion, homeopathy works mainly by the placebo effect. While this can be effective for pain, depression and other neurological ailments, it cannot, in my opinion, suddenly increase sperm/egg production, increase the viability of those cells, unblock tubes or miraculously cure other reasons why a person may be infertile.
