Low sex-drive

My husband and I have been TTC for 9 months now (trying without trying he says). Which to him means we won’t use protection and if it happens it happens, but to me I have been tracking my ovulation over the last 9 months amongst other things. My husband suffers from anxiety and depression and over the summer he found out he has VERY low testosterone levels (currently at 74 when he should be between 200-400). Having low test obviously lowers your sex drive so it’s making the whole baby making process a bit difficult. Low testosterone can also cause low sperm count...He’s only 29 (soon to be 30) UGH

Has anyone else been in a similar situation? I’m so worried we won’t be able to get pregnant. Any suggestions are so greatly appreciated!
