I would think that the pill, both the men's and the women's version, would be imminently more preferable to an injection any day of the week? Particularly injections which require preparatory injections to numb pain deemed to exceed acceptable FDA levels for humans. If there is a men's and women's version of a pill, and a men's and women's version of an injection, most men and women would choose the pill.

That seems common sense to me, not squeamish-ness. This pill will garner infinitely many more users. (I mean, assuming it works I guess?)
