IMPERFORATE HYMEN.
Reading edition
Cases of this kind have been described in mare and cow, preventing copulation and conception, and leading to a distension of the vagina, with a glairy fluid, which obstructed defecation, irritated the bladder and caused violent but fruitless straining, under which the mass would project from the vulva. The centre of the swelling may be penetrated with a trochar or bistuory and enlarged by incisions in several directions. Relief is prompt and lasting.
