Abstract: | The following is a report on a congenital vaginal malformation, imperforate vagina, in
the common marmoset (Callithrix jacchus). This anomaly was observed for
the first time in an adult female in our research colony. There was no uterine and vaginal
aplasia or atresia in her grossly normal genital tract. The plasma progesterone
concentration suggested that the ovarian cycle had ceased. However, this may not be
related to a functional anomaly, but rather to suppressed ovulation resulting from
subordination to cagemates considering the various stages of follicular development
observed. |
