Why wouldn't hormone fluctuations have the potential to alter emotional or mental health symptoms? They have the potential to alter almost everything else in the body. I think to dismiss PMDD completely is to not realize the profound connection mind and body can have. Especially considering anxiety in particular can have very real physical symptoms.

There is nothing sexist about acknowledging a potential link between mood and hormones. It IS on the other hand sexist to write off someone entirely for said hormones.

Hormones affect a males' personality and temperament too, so there is nothing sexist about it. Men with higher levels of testosterone tend to be more aggressive, have higher libidos. Men with testosterone deficiencies may have symptoms of fatigue and depression.
