The authors, in this article, have reviewed the different proofs that confirm that Halban's fascia does exist. The authors have been able to find, separate out and use Halban's fascia in a series of 263 vaginal operations for genital prolapse taking the anatomo-surgical approach. From the histological approach, they have shown that Halban's fascia is constituted by fibro-connective tissue strips between which there are large numbers of blood vessels and muscles and nerve endings. From the point of view of embryogenesis, they believe that Halban's fascia comes from the same mesenchyme layer as that which gives rise to the corpus spongiosus of the penis. As far as sexual physiology is concerned, the authors review the various clinical experiments that have been carried out throughout the world medical literature which shows that there is an erogenous zone in the upper anterior part of the vagina and they believe that Halban's facia, which is homologous with the corpus spongiosus, is the site of origin of vaginal orgasm. Finally, as far as physiology and biology of reproduction is concerned, they believe that the vaginal fluid that is secreted by Halban's fascia during intercourse plays an important role for the survival of spermatozoa.
