Progestin Exposure Before Gonadotropin Stimulation Improves Embryo Development after In Vitro Fertilization in the Domestic Cat1
- BiologyBiology of reproduction
- 2010
Results indicate that prior exposure to exogenous progestin (via implant) or endogenous progestagen (via spontaneous ovulation) improves ovarian responsiveness to gonadotropins in the cat through a mechanism that is independent of the induction of ovarian quiescence.

Nonsurgical embryo transfer in the scimitar‐horned oryx (Oryx dammah): Birth of a live offspring
- Biology
- 1991
A healthy female calf born at 247 days post-transfer represents the first known live birth of scimitarhorned oryx following embryo transfer, providing additional evidence that estrous synchronization and embryo transfer techniques used in other ungulates can be applied to endangered antelopes such as the scimitarian-horning oryx.
Monitoring ovarian function in scimitar‐horned oryx (Oryx dammah) by measurement of fecal 20α‐progestagen metabolites
- Biology, Medicine
- 1995
It is concluded that measurement of immunoreactive 20α-progestagen concentrations in feces has limited application for predicting ovulation or accurately timing inseminations because of delay in steroid excretion, but will enable noninvasive monitoring of ovarian cycles in scimitar-horned oryx for fertility assessment and for determining the outcome of artificial insemination programs.
