Hormonal stimulation and embryo collection in the domestic cat (Felis catus)
1987 Theriogenology (28): 915-927
Sexually mature domestic cats (Felis catus) were treated with one of eight hormone regimens to induce estrus, follicular development and super-ovulation. Queens were allowed to breed naturally following hormonal stimulation, and laparotomy was utilized to observe ovarian response and to perform successful repeated surgical collections of transferable quality embryos with the domestic cat. The regimen which evoked the most desirable results in terms of ovarian response and embryo recovery was a subcutaneous injection of follicle stimulating hormone-pituitary (FSH-P) once every 24h for 6 d on the amount of 0.75 mg/d for the first 5 d and 0.25 mg on the 6 d, followed by two 375 IU intramuscular injections of human chorionic gonadotropin (Hcg) 24 h apart, beginning on the same day as the sixth injection of FSH-P.
