Speaking generally, relations during the menses should be discouraged. There are several reasons for it. The first reason, which need not be gone into in detail, is an esthetic one. The second reason is that intercourse during menstruation may in some cases lead to congestion of the uterus and ovaries. Third, the menstrual discharge, which as we know does not consist of pure blood but is a mixture of blood, mucus, and degenerated lining membrane of the uterus, may give rise to a catarrh of the urethra in the man. Fourth, and this is a point to be borne in mind, any discharge that a woman may be suffering from is always aggravated during menstruation. For these reasons relations during the menses are undesirable. But where the woman has strong libido during that time and has no libido at any other time, relations may be indulged in during the last day or two of the menses. Any unpleasantness may be obviated and any discharge may be removed by the woman taking a mild, warm, antiseptic injection before coitus. The ancient idea of the injuriousness of the relations during menstruation and the disastrous results likely to follow them have only a very slender foundation. They rest on no scientific basis and though it may be sad to state facts, there are many couples who do indulge in such relations as a regular thing and without any injury to either husband or wife.
