Lower elements resemble「weakened」(尢) inside「spread legs」with upper element of「reaming (刀, 免)」「erection in orifice(s)」with「bent penis」(bent by past scarring but no longer infectious perhaps) that leads to the meaning to PARDON, PERMIT, to EXCUSE, a LICENSE TO DO after an examination to prove ability, or testing of one's worthiness. Suggested as a variant of「escape from, evade, removed from one's official position」(免), but it appears as if the elements are slightly different, and may be referring to escaping death by receiving timely medical attention treating a sexually transmitted infection.
　Top element as reamer or sword describes as an ancient episiotomy, a surgical incision of the perineum to enlarge the vagina and so facilitate delivery during childbirth, or, as a symphysiotomy (cutting the pubic bone in half, splitting the vulva into「two sides」):「Before the Caesarean section technique was available, if labor failed to progress because the head of the fetus was too large, the mother's symphysis pubis was cut and the skull of the fetus was crushed.」

　Likely, the master or husband was required to PERMIT this procedure and EXCUSE the surgeon if anyone died.
　As perhaps the moment of parturition of a very difficult birth and providing some additional aid to deliver the infant depicts someone else saving one or both of the mother and infant during a difficult birth, to mean ESCAPE DEATH. Simply living through the experience might mean「escape from trouble.」Childbirth was the leading cause of death among women, and still is in many places. After a very difficult birth (or any birth, for that matter), the mother is no longer pregnant and RELIEVED OF A BURDEN (see related glyph 壬 as「pregnant」that also means「burdened」).
　The norm in old Chinese brothels was not to copulate into the vagina, but rather use no-longer-integrated feet, the anus, mouth, breasts, or what have you…to PERMIT spurting semen while copulating into a vagina leads to CHILDBIRTH, and the spread of disease, both conditions that placed valued revenue-raising assets out-of-service and not in the best interests of the shaman proprietress.
　Some browsers will not display this glyph using certain fonts…the actual glyph may possibly be seen within other glyphs as an element.
