Husband Advice Needed 🤵🤰🙏

My husband took an at home fertility test and we got the faintest line showing normal sperm count so I assume he is on the low side. Of course like most husbands I'm sure they want to do minimum effort. He has made it almost impossible to find a urologist since he wants a female and there are none in the area that deal with males. I was wondering if anyone knows of vitamins he should be taking? For example, has anybody used Fertileaid and had success?
