As are extinct the users. My argument stands.
The death-rates for young people, especially women were quite horrendous during Roman times and mostly precisely because of anything birth-related. If you didn't die in child-birth, you died making abortion and if you didn't, you died of the infection or blood poisoning you got while doing the abortion. If (a big if) you reached your 30th birthday, you had decent chance to live to be old, which became even better if you reached 40 years, but the nubile years were quite deadly for both genders, but especially women and there are plenty of statistics to prove this from the bone samples.
Also notice that after Rome fell to barbarians, the world went to shit and most of the Roman tech and medicinal knowledge became literally lostech during the so called "dark ages" and many things were reinvented only relatively lately during the renaissance. Just because there was penicilin during the medieval doesn't mean anybody knew actually how to use it.
