Abstrakt: Analysis of urinary estrone conjugates and pregnanediol-3-glucuronide were used to document ovarian events in female gorillas known to be fertile. These normal parameters were used to assess ovarian function in gorillas suspected as infertile. Insufficient luteal hormonal dynamics were observed in the infertile group. Based on this observation, exogenous progesterone as the only treatment was administered to infertile females post ovulation and mating. Positive pregnancy tests were observed in all 3 females during the progesterone treatment and one full-term pregnancy resulted. This successful treatment supports the concept that insufficient progesterone secretion may be a contributing factor to the infertility of captive female gorillas. The present data demonstrate the utility of urinary assays for evaluating ovarian function in gorillas and suggest that one type of infertility may be resolved with progesterone therapy.
