Specifically, in the UK, egg freezing costs range from approximately £3,300 to £3,900 for the procedure, with annual storage fees between £350 and £400. [ 16 ]
Oocyte (or ovum/egg) activation is a series of processes that occur in the oocyte during fertilization. Sperm entry causes calcium release into the oocyte. In mammals, this is caused by the introduction of phospholipase C isoform zeta (PLCζ) from the sperm cytoplasm. [ 1 ]
In current state of the art, early embryos having undergone cryopreservation implant at the same rate as equivalent fresh counterparts. [2] The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, [3] [8] also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI).

“Some women freeze eggs because they do not currently have a partner or do not wish to become pregnant today but are concerned about the loss of eggs that occurs as the woman ages. Other women ...
Hyperactivity of theca cells causes hyperandrogenism, and hypoactivity leads to a lack of estrogen. [5] Granulosa cell tumors, while rare (less than 5% of ovarian cancers), may both granulosa cells and theca cells. [6] Thecomas are benign proliferations of theca cells that may present with hormonal dysfunction. [7]
