The authors confirm that all data underlying the findings are fully available without restriction. All relevant data are within the paper. There are increasing numbers of reports describing human vaginal tissue composition in women with and without pelvic organ prolapse with conflicting results. The aim of this study was to compare ovine and human posterior vaginal tissue in terms of histological and biochemical tissue composition and to assess passive biomechanical properties of ovine vagina to further characterise this animal model for pelvic organ prolapse research. Both sheep and human vaginal tissue showed comparable tissue composition.
Reproductive system in sheeps and goats
Domestic sheep reproduction - Wikipedia
If you've ever wondered what things look like to your vagina mid-bone, you're in luck. A few intrepid researchers decided to film sex from the vagina's point of view, and the result is a fascinating video that's years old but is resurfacing again to everyone's benefit. In this segment of the episode, testers attached cameras to one of the woman's nipples, the man's penis, inside the woman's vagina, and both people's skin. Once their parts were fully equipped with camera gear, the couple started to have sex in the missionary position. Thanks to the various cameras, the resulting video has a few different angles—it's clear that the experimenters were nothing if not thorough.
A sheep vagina is the most similar to a human vagina
As with other mammals , domestic sheep reproduction occurs sexually. Their reproductive strategy is very similar to other domestic herd animals. A flock of sheep is generally mated by a single ram, which has either been chosen by a farmer or has established dominance through physical contest with other rams in feral populations. Largely as a result of the influence of humans in sheep breeding, ewes often produce multiple lambs. This increase in the lamb births, both in number and birth weight, may cause problems in delivery and lamb survival, requiring the intervention of shepherds.
