Some men don't develop much facial hair. That's just the way they are.
A question like this has to be put in more general terms such as "Why are men more often capable of growing noticeable moustaches" Some men cannot grow a moustache and some women can. It is a matter of genetics and hormonal levels.

The hormonal change that triggers the start of menstruation is an increase in estrogen levels in the body.
Girls have hair above their lips, commonly referred to as a mustache or facial hair, due to natural hormonal variations. Both men and women have hair follicles on their faces, but hormonal levels, particularly androgens, can influence hair growth. Genetics also play a role in the density and visibility of this hair. It's a normal aspect of human biology and varies widely among individuals.
It is the other way around. Dropping hormone levels cause menopause.
A hormonal reaction is the body's response to changes in hormone levels. Hormones are chemical messengers that regulate various bodily functions, including metabolism, growth, and reproduction. When hormone levels fluctuate, the body may experience physical or emotional changes in response.
Fibroids are benign tumors that can develop in the uterus due to hormonal imbalances, genetic factors, and estrogen levels. They can also be influenced by factors like age, obesity, and family history. The exact cause of fibroids is not fully understood.

A blastocyst is an early stage of embryo development that forms around 5-6 days after fertilization. It requires specific environmental conditions within the mother's reproductive tract, such as appropriate nutrient levels and hormonal signals, to develop successfully. If the environment is not favorable, the blastocyst may not implant or develop properly.
Hormonal function is when your hormone levels go up and down. To be more specific, it would depend on what hormone is fluctuating and other factors such as age gender and/or environmental factors.
You normally find it in the lower levels of your neighbours, and normally on the cost bit :)
