Husband has low T and is supplementing with testosterone. Will this affect sway?

So, I just purchased the plan, but thought I would post this on here in case anyone else has this issue. My husband is 45. We have two boys ages 5 and 7. He has been on testosterone supplementation for low T for about 9 months or so. This is actually quite common in men as they age. I mentioned to my husband (a physician) my fear his supplementation would sway blue, but my husband said that supplementing with testosterone actually inhibits sperm production because the "fake testosterone" he is getting via shots is signaling to the brain for it to quit making sperm...thus, he believes that his supplementation will not affect our sway. Yet, I was reading the studies saying that men in certain fields had more girls. I was not clear if this was due to low testosterone levels or because the fields caused decrease sperm count due to environmental exposure such as in the case of deep sea divers, anesthesiologists, fighter pilots, etc. It would seem to me that someone like a fighter pilot or deep sea diver, for example, would probably be MORE likely to have high T (since they are sort of hyper masculine professions) but a low sperm count due to environmental factors.

Any thoughts?

I found the below at the following website (https://www.everydayhealth.com/hs/lo...cts-fertility/) that seems to suggest that supplementing his T would sway girl:

"One treatment for low testosterone is testosterone replacement therapy. But taking testosterone can hurt your fertility, Dr. Nagler says. Here’s why:

A part of the brain (the hypothalamus) and the pituitary gland, which sits just below it, help control male fertility. The hypothalamus produces a chemical, gonadotropin-releasing hormone (GnRH) that sends a message to the pituitary gland to tell it to produce two important fertility hormones: luteinizing hormone (LH) and follicle-stimulating hormone (FSH). FSH triggers the creation of sperm cells. LH tells the testes to produce testosterone, which is needed for sperm production.

When you take testosterone, your brain thinks it's done its job and slows down the production of GnRH. Because it’s not getting the message, your pituitary gland no longer produces normal levels of the other hormones, FSH and LH, needed to make sperm. As a result, your sperm production decreases. The lower your sperm count, the less chance you have of fathering a child."

The truth is we honestly do not know. We have hardly any real information about what actually sways, and the data suggesting testosterone sways to begin with is...shall we say...sketchy at best, most of it based on personality quizzes and not ever measurements of anyone's testosterone levels. And men, testosterone, and gender conceived, the data is nonexistent and based on totally unproven assumptions

WE operate under the assumption that men with low sperm count have more girls because we have SEEN many of our men who have low sperm count having girls. So it is my belief that you're correct that testosterone supplementation may sway somewhat pink, although we've had couples conceive both boys and girls with them.

The truth is we just don't know. My advice is for you guys to do what has worked for most people most of the time, and not worry about the things you can't control, that you need to continue for your overall health and well being.
