Unilateral ovarian absence in two capuchin monkeys

Area of Science:

• Reproductive Biology
• Primate Anatomy
• Comparative Pathology

Background:

• Ovarian absence is a rare congenital or traumatic condition.
• Understanding its occurrence in non-human primates is crucial for comparative studies.

Observation:

• Two capuchin monkeys were examined through gross and microscopic analysis.
• Detailed anatomical descriptions were recorded for reproductive organs.

Findings:

• Case 1 exhibited right ovarian and distal uterine tube absence, bilateral fimbrial absence, and a rudimentary uterus.
• Case 2 presented with unilateral ovarian absence but a functional contralateral ovary and a normal uterus.

Implications:

• This study reports unilateral ovarian absence in capuchin monkeys for the first time.
• Findings contribute to the understanding of reproductive system variations in primates.
• May inform future research on primate reproductive health and development.
