But the truth is that mammals all have exactly two ovaries! Pigs use two ovaries for their 7-14 piglets and it’s the uterine body that needs to adapt to fit them all. www.frontiersin.org/files/Articl...
A figure showing a human, pig, rat, and sheep uterus. The vagina, cervix, uterine body, uterine fundus, uterine horns, and fallopian tubes/oviducts are given specific colors so that the structures can be identified in the different species despite their different shapes. The human uterus has a simplex shape with the fundus at the top, body below, followed by a short cervix and a longer vagina. The pig uterus has two uterine horns that wind back on themselves, a fundus with a fold, a uterine body that joins the horns before leading into a very long cervix, and some vagina shown. The rat uterus has two thin straight uterine horns, with a fundus with a fold and a uterine body connecting the two horns. The cervix is short and the vagina is shown to be short as well. The sheep uterus has two uterine horns that are shown at an angle to the uterine body and are relatively short and squat. The uterine body is long, with a more flat fundus than the pig or rat. The cervix is the shortest of all four with a large and long vagina shown. Text at the bottom labels the species with the volume of the uterus estimated as follows: human: ~34 mL. Pig: ~620 mL. Rat: ~0.4 mL. Sheep: ~56 mL. Finally, the change in volume during pregnancy is given as follows: human: 200x. Pig: 35x. Rat: 175x. Sheep: 120x.

Hi Erik, I think genetics fits in other biology. My ORCID is here: orcid.org/0000-0002-62... I’d love to be added to the science feed, to spread the science of uterine function!
