Gender plays a vital role in human society. To me these two images capture the very definitions of masculine and feminine.
In the English language, the word
man comes from Latin, "manus" for hand. Men were seen as the hands that do the physical labor: The producers and constructors of civilizations.
woman OTOH, is an acronym of
man: Women are the carers in society.
As such a steady flow of resources from the producers to the carers is a reasonable expectation. It enables them to perform essential caring duties, that otherwise provide no remuneration. In terms of continuing human species, women and children are precious while men are a valuable but more expendable commodity.
Unlike contemporary dictionary definitions that redefine man and woman as synonyms for an adult male or female, understanding the original concept not as a reproductive sex, but as a person's role in society is fundamental to fully understanding gynocentrism and patriarchy theory.
Evolution by it's very nature produces gender symbiosis: Oppression (or exploitation) of one sex by the other will always be balanced with a reciprocal concession because in the struggle for survival we need to compete effectively with rival species.
For instance a woman's confinement during reproduction, must one way or an other, impose on the male that he assumes responsibility for her welfare. Otherwise, if he should default, then his genes would be less likely to survive.

Reproductive dimorphism that is either male or female. Inter-sex conditions are a malfunction, not a separate sex.
Collection of all behavior patterns that are statistically correlated with biological sex.
reproductive sex is in the genitals gender is in the mind
Physical difference was represented in adjacent graphic illustration sent into deep space. It's intention to potentially introduce humanity to an as yet unknown alien intelligence. My subjective impression is that subconsciously the diagram also captures the subtle difference in typical gender roles of the sexes in their body language: The male faces the alien stranger (taking the risks), while the female looks to him for her protection.
Besides instinct, a person's behavior will be influenced by cultural, religious, or other conditioning. Thus at the level of the individual all kinds of variations are found. In our technological era there are plenty of ways we can contribute to society, beyond making babies.
One reason that gender remains relevant today is that people who tend towards the caring roles will somehow still need to be supported in that endeavour by the productive ones.
Conversely, does it actually matter what reproductive sex that person has? Well... I don't think so! Sexual discrimination and prejudice serves no purpose at all. Let people pursue what we aspire to and if some really do need medical intervention to feel comfortable doing that, what difference does it make to you?
