Abstract
A study of a total of 397 pregnant sex organs from goats in various stages of pregnancy was undertaken. The volume of the uterus increases rapidly after conception. Even with one foetus in each uterine horn the uterus will at times be definitely asymmetrical. An uneven distribution of the caruncles in the uterus is often found. The number found averaged 120—125, with an average of 61.3 and 60.7 caruncles in the right and left uterine horn respectively. In the ovaries, in addition to the corpus luteum of pregnancy, follicles of up to 1 cm in diameter are often observed. The ovaries increase in size with the number of corpora lutea present. When the ovary contains two corpora lutea these are on the average smaller than when only one corpus luteum is present. A variation in the diameter of the corpus luteum from 0.30 cm to 2.70 cm was found. A significant increase in the size of the corpus luteum with the increasing size of the foetus was found.
