Ovarian follicles were aspirated from superovulated heifers at different periods from the beginning of standing heat. The follicular fluid of these follicles was analyzed for progesterone, estradiol, testosterone and androstenedione concentrations and compared to the maturation stages of the oocytes and their ability to undergo fertilization in vitro. The results obtained suggest that high concentrations of progesterone, testosterone and androstenedione compared to a lower concentration of estradiol correspond to a high proportion of M-II oocytes and a high in vitro fertilization rate.
从发情开始后的不同时期,对超数排卵的小母牛的卵巢卵泡进行抽吸。分析这些卵泡的卵泡液中孕酮、雌二醇、睾酮和雄烯二酮的浓度,并与卵母细胞的成熟阶段及其体外受精能力进行比较。所得结果表明,与较低浓度的雌二醇相比,高浓度的孕酮、睾酮和雄烯二酮对应着高比例的M-II期卵母细胞和高体外受精率。
