How can you use “preovulatory” in a sentence? Here are some example sentences to help you improve your vocabulary:
Finally, with regard to FSH action, FS has been shown to neutralize the bioactivity of the FSH inhibitor, BMP-15 [ 39 ] . It is possible, therefore, that the strong expression of FS by the DF may serve to modulate BMP-15 action such that sufficient FSH receptors are expressed in the GC to permit the development of a preovulatory follicle.
In other words, cells lacking surface LHR may not be influenced by temporary increase of LH production during the preovulatory period of the ovarian cycle due to the "cell membrane LHR barrier," and the LH effect is probably also prevented by the "vascular LHR barrier."
A number of reports have characterized constitutive expression of HSP70 and HSP90 in both immature oocytes and ovulated eggs from various species [ 32 33 34 35 36 ] . HSP70 and HSP89 are constitutively synthesized in the immature, preovulatory mouse oocyte, although the expression is not heat-inducible [ 37 ] . Levels of HSP70 mRNA decrease following oocyte maturation and ovulation [ 38 ] , and HSP70 is one of the first genes to be transcribed at the onset of zygotic gene activation in the early 2-cell mouse embryo [ 39 40 ] . Interestingly, while previous investigators did not localize HSP70 to the oolemma, they did demonstrate that the presence of anti-HSP70 antibody reduces bovine sperm-egg binding in vitro.
In porcine ovaries, LHR expression was detected in granulosa and theca cells of preovulatory follicles, but not in granulosa lutein cells of the mature CL [ 27 ] . In human ovaries, LHR expression was also detected in granulosa and theca cells of preovulatory follicles, but mature CL showed strong expression in luteal cells, which disappeared during luteal regression.
However, in porcine preovulatory ovaries (late follicular phase), which contain numerous preovulatory follicles but no luteal tissue, very strong LHR immunoreactivity was also detected (lane 3, Fig.
