Abstract

Preservation of the genetic diversity of the captive orangutan, especially the wild-caught founders, is critical in maintaining a long-termpopulation in zoological parks. One solution to the problem of maintaining maximum genetic diversity would be to initiate a program of artificial insemination for genetically underrepresented individuals through the banking and interinstitutional use of cryopreserved semen. However, little is known about basic orangutan semen characteristics, and current methodology is inadequate to support such a program. In this paper, we report the results of semen collection from an adult Sumatranorangutan (Pongo pygmaeus abelii), using an artificial vagina withoutanesthesia or electrical stimulation. A total of 27 ejaculates were evaluated during a 1-year period. The total and liquid volumes of the ejaculates at 1 h following collection were 6.1 +/- 0.6 ml and 2.6 +/- 0.4 ml, respectively (mean +/- SEM). The liquid portion continued to exude semen for 2 h; however, 90% of the motile sperm was exuded withinthe first 30 min. The total number of sperm in the ejaculate was 164 x 10(6) +/- 16.5, and the percentage of motile cells was 60 +/- 2.7%. We conclude that the artificial vagina provides a promising technique for semen collection in the orangutan, and view these results as an initial step in developing methods for in vitro sperm capacitation, sperm cryopreservation, and artificial insemination.
