Apart from presenting something of a red rag to a bull, the Lancet does have some possible medical context for quoting, "Historically, the anatomy and physiology of bodies with vaginas have been neglected." The point being that this is a very specific area of women's health.
Vaginas have been neglected even more than the rest of the female body in medical study, though not necessarily in practice - Intra-uterine contraceptive devices are one of many interventions which took place with insufficient research. There is a condition related to extremely painful periods - I misremember its name, sorry - that has only in the last couple of years been taken seriously enough to warrant proper treatment.
I would have to read the quote in context, but would not be surprised to find it arises in consideration of the greater focus on issues of the male reproductive organs than on the female up to now within medical education and scientific study.
Whether it merits a front page? The subject certainly does. Too irreverent? Maybe. I saw it as rather radical, considering current and historical context. Possibly I just have a peculiar sense of humour.
