In small hatchery, it was observed that the female brood fish ovulated, but failed to spawn naturally. 小型孵化环道条件下,亲鱼能排卵,但不能自然产卵。
Similarly, a fertilization rate of 83.3% was also obtained when the capacitated spermatozoa were cultured with ovulated oocytes of ewes for 7-9 h. 获能精子与同种卵的受精率为83.3%。
The Reproductive Physiology Study of Post ovulated Anguilla japonica 产后鳗鲡生殖生理学的研究
Objective To investigate the clinical features and pregnant outcomes of infertile women ovulated with small follicle ( OSF). 目的探讨小卵泡排卵不孕患者的临床特征及妊娠结局。
When the oocytes are ovulated from the ovary into oviduct, the granulosa cells ( cumulus cells) detached from the oocytes, and the dependence of oocytes on cumulus cells is decreased. 当卵母细胞发育到MⅡ期并从卵巢中排出到输卵管后,卵母细胞对颗粒细胞的依赖逐渐解除。
Fertility depends on the level of maternal growth and development of ovarian follicles as ovulation follicle development determines the number of ovum ovulated which is the key factor affecting the fecundity. 繁殖力的高低取决于母体卵巢卵泡的生长发育,因为卵泡发育决定了排卵数,是影响繁殖力的关键因素。
Angiogenesis play essential function in the follicle development and the selection of ovulated follicles Especially in the maintain of vascular permeability. 血管新生在卵泡的生长后期和排卵卵泡的选择上起到了至关重要的作用。
The objective of this study was to test this hypothesis. Newly ovulated mouse oocytes were cultured in the CZB medium supplemented with different concentrations of pyruvate before treated for activation or assayed for MPF activity. 为了验证这个猜测,我们将新排卵的小鼠卵母细胞培养在添加不同浓度丙酮酸的CZB中,然后进行激活处理或通过放射自显影的方法分析MPF活性。
