The reproductive tract of ewes and does is similar. The female reproductive tract consists of the vulva labia, vagina copulatory organ , cervix, body of the uterus, uterine horns, oviduct also called Fallopian tube and the ovary. The male reproductive system consists of testicles, which produce sperm and sex hormones, a duct system for sperm transport, accessory sex glands, and the penis, or male organ of copulation, which deposits semen in the female. Once puberty is reached, large domestic animals such as sheep and goats display a polyestrous repeated reproductive cycles pattern of reproductive activity.

INTRODUCTION
Access to readily available large animal models and sensitive non-invasive techniques that can be used for the evaluation of microbicide-induced changes in tissue could significantly facilitate pre-clinical evaluations of microbicide safety. The sheep cervicovaginal tract, with stratified squamous epithelium similar to humans, holds promise as a large animal model used prior to non-human primates. In addition, optical coherence tomography OCT could enable high resolution visualization of tissue morphology and non-invasive assessment of microbicide-induced epithelial injury. We evaluated the dose response of sheep cervicovaginal tract to benzalkonium chloride BZK. Pre- and post-treatment colposcopy and OCT images were collected and graded based on WHO criteria and a previously reported scoring system, respectively. Biopsies were collected and the degree of epithelial injury and its thickness was assessed based on histology and OCT. The sheep cervicovagina exhibited anatomical and microscopic features similar to the human. Colposcopy detected findings in half of sheep and OCT in all sheep treated with 0. OCT detected differences in the 0. The sheep cervicovagina is similar to humans, and exhibits dose dependent epithelial changes following BZK treatment.
