This study was conducted to investigate expression of matrix metalloproteinases (MMPs) and ovarian morphological changes in androgenized cyclic female guinea pigs. Adult cyclic female guinea pigs were injected daily for 28 days with medium doses of testosterone propionate (TP; 1mg/100g), high doses of TP (2mg/100g), or saline (control). Serum concentrations of testosterone, estradiol (E2), and progesterone...
The present study was conducted to investigate expression of matrix metalloproteinases (MMPs) and early ovarian development in neonatal guinea pigs. Thirty neonatal guinea pigs at 3 or 8 days of age were administrated 5IU equine chorionic gonadotropin (eCG) or saline, and the ovaries were collected after 2 days of eCG.
