Downregulation of luteinizing hormone and follicle-stimulating hormone receptors after hCG and eCG treatments in the porcine oviduct

The influence of induction of ovulation and superovulation with eCG and hCG on LH and FSH receptor levels in porcine oviducts on day 3 post coitum was studied. In experiment I, gilts were assigned into cyclic (control; n=5) and inseminated (control; n=5) groups. In experiment II, there were three groups of animals: inseminated (n=5), induced ovulation/inseminated (750 IU eCG, 500 IU hCG; n=5) and superovulated/inseminated (1500 IU eCG, 1000 IU hCG; n=5) gilts. Oviduct tissues were collected 3 d after insemination or PBS infusion.
