In humans, exosomal miRNAs present in follicular fluid were associated with hormonal concentrations, such as miR-132, miR-320, miR-520c-3p, miR-24, and miR-222 involved in the regulation of estradiol concentrations, while miR-24, miR-193b, and miR-483-5p are involved in the regulation of progesterone concentrations.
Other maturation-preventing factors in follicular fluid are oocyte maturation inhibitor (57) and hypoxanthine, (58) which acts only in combination with cAMP.
Follicular fluid plays an important role in folliculogenesis, maturation of oocytes, granulosa cells, luteinizing and ovulation [14] Several studies have shown that pre ovulation, follicular fluid as a medium or as a supplement that is able to stimulate the natural environment on the maturation of oocytes [15,16].
Teissier (14) in the human, Grondahl (13) in the equine, Sirotkin (15) in the porcine and Zhao (16) in the rat reported that elevated estradiol in the follicular fluid indicate a more advanced stage of oocyte maturation.
Further tests showed that, in some cases, the bacteria had been transferred from the lower genital tract to the follicular fluid during the medical procedure used to collect eggs known as transvaginal oocyte retrieval (TVOR).
Estradiol is released by the granulosa cells into the follicular fluid. A small portion of this hormone can diffuse out of the follicle and enter the blood.
(35) Although they found substantial amounts of mifepristone in follicular fluid, the in vitro fertilization and cleavage rates of the collected oocytes were not affected.
"We found that women with abnormalautoantibodies in blood also have abnormal antoantibodies in follicular fluid,' Gleicher told SCIENCE NEWS.
