Any definition must include first two points, thought.

Kids of both sexes pre-puberty are not producing any gametes.

Women after menopause and men after andropause are not producing any gametes.

Women's periods/menstruation is periodic and not dependent on our will releasing and maturing of an egg. So we don't produce them all the time (plus all our eggs we have from birth, so we not producing them at all, only releasing and maturing them one by one). And periods can be irregular because of nerves or health issues, periods can stop due to pregnancy, and so on.

So first two points MUST be included in definition of a woman and man, as 100% of men and women have first point and 100% of women have second point.

Around 15-25% of all women also have issues with health and need reproductive organs to be removed at one point in life.

So any definition must include point 3 as well - or up to 1/8 of population will be not defined.

I have strong feeling that people asking those questions are either males or very young females - so they have no idea about female anatomy at all and thinking that male anatomy is standart and is universal and that women's reproductive systems are similar to theirs.
