Влияние низкотемпературного хранения на стабильность содержания стероидных гормонов в фолликулярной жидкости яичника человека

There was studied the estradiol (E), progesterone (P) and testosterone (T) content in follicular fluid (FF) of human oocyte preovulatory follicles, native and low-temperature-stored one (-196°C). We have compared the effect of two freezing regimens (one-step immersion into liquid nitrogen and a two...

Zusammenfassung:There was studied the estradiol (E), progesterone (P) and testosterone (T) content in follicular fluid (FF) of human oocyte preovulatory follicles, native and low-temperature-stored one (-196°C). We have compared the effect of two freezing regimens (one-step immersion into liquid nitrogen and a two-step one with the preliminary exposure in nitrogen vapors) on the stability of concentration maintenance of these hormones in FF for 1 and 6 months. Stability of estradiol, progesterone and testosterone was shown to be kept within the whole observation period and to be independent upon the FL freezing regimen selected.
