Cetrorelix suppresses the preovulatory LH surge and ovulation induced by ovulation-inducing factor (OIF) present in llama seminal plasma
BACKGROUND The purpose of the study was to determine if the effect of llama OIF on LH secretion is mediated by stimulation of the hypothalamus or pituitary gland. METHODS Using a 2-by-2 factorial design to examine the effects of OIF vs GnRH with or without a GnRH antagonist, llamas with a growing ovarian follicle greater than or equal to 8 mm were assigned randomly to four groups (n = 7 per g...
متن کاملBiological Characterization of Ovulation-inducing Factor (oif) in Llama Seminal Plasma
The purpose of the studies reported in this thesis was to provide a better understanding of the effects of purified ovulation-inducing factor (OIF) from llama seminal plasma in reflex ovulators (lama glama) and spontaneous ovulators (Bos taurus). The objective of the first study was to determine if the dose of OIF of llama seminal plasma required to elicit ovulation is physiologically relevant,...
متن کاملOvulation-inducing factor: a protein component of llama seminal plasma
BACKGROUND Previously, we documented the presence of ovulation-inducing factor (OIF) in the seminal plasma of llamas and alpacas. The purpose of the study was to define the biochemical characteristics of the molecule(s) in seminal plasma responsible for inducing ovulation. METHODS In Experiment 1, llama seminal plasma was centrifuged using filtration devices with nominal molecular mass cut-of...
متن کاملIs an ovulation-inducing factor (OIF) present in the seminal plasma of rabbits?
The objectives of this study were (1) to determine the effect of rabbit seminal plasma on LH secretion and ovulation using the llama animal model as an in vivo ovulation bioassay and (2) to determine the effect of llama or rabbit seminal plasma on ovulation induction in the rabbit model. In Experiment 1, llamas with a growing follicle ≥8mm in diameter were assigned randomly to one of three grou...
