Being a guy, one would think the article wouldn't pertain to me and yet I read it looking for that part in the middle you mentioned, and found something there even I identified with. "the fight or flight response: as adrenaline and catecholamines are released in the brain, nonessential systems such as digestion and, yes, sexual response, close down; circulation constricts, because the heart needs all the blood available to help the body run or fight; and the message to the body is 'get me out of here.' "

In my case testosterone is a hormone involved, of course, but in my PTSD recovery blood tests found my testosterone level to be really low. About half as much as normal. I had to have testosterone shots for a year every week.

Interesting and possibly related to what this article says about female response to stress, too. Certainly a similar result in my lifestyle.
