Did he imply he wanted to have sex with her? Or did he say something vague about “helping”? Bc those are two different things. The latter could range from being supportive of the very time-consuming process of infertility treatment/medical care that is needed that will take her out of the office, to a host of other issues. Yes, it’s a personal and private matter, and yes, he could have said something awkwardly, but he may not have been suggesting that he raw dog your wife. If she had been spoken to like that, she’d have known it.
