Earlier quoted context omitted.
I hear you. But women can continue the line —society. Men can’t bear children —society dies. Men get sent to war, women stay in the homeland, many of the men may not return and the women may have to persevere, with sacrifice but society can push on. If it were reversed, that society may well collapse. The Spartans didn’t send their women off and let the men stay back in the homeland.
This sounds like discrimination. Only women can produce offspring? Too bad, so sad. Everyone serves if it is required.
The onus is on you to show that it is bad in this case. We discriminate routinely, children are exempt from working for example.
