“…It would be a useful treatment option for women who are at risk of losing their ovarian function because of pelvic diseases, surgery or radio/ chemotherapy and could also avoid some of the moral and ethical problems posed by embryo freezing. Although several pregnancies and live births following freezing and thawing of human oocytes have been reported [1][2][3][4][5][6][7][8][9][10][11][12][13], human oocyte freezing as a technology is still considered to be at an early developmental stage. Improving pregnancy rates associated with the use of cryopreserved human oocytes would be a major advance in human ART.…”

Mammalian oocytes have proven to be more difficult to cryopreserve than cleavage-stage embryos [17], and the efficiency of oocyte cryopreservation in most species, except for the mouse, is still very low (for a review, see [18]).…”

Abstract. Improving pregnancy rates associated with the use of cryopreserved human oocytes would be an important advance in human assisted reproductive technology (ART). Vitrification allows glasslike solidification of a solution without ice crystal formation in the living cells. We have attempted to improve the survival rates of oocytes by a vitrification technique using bovine models. In vitro matured oocytes with or without cumulus cells were vitrified with either 15.0% (v/v) ethylene glycol (EG) + 15% (v/v) dimethylsulfoxide (DMSO) + 0.5 M sucrose or 15% (v/v) EG + 15% (v/v) 1,2-propanediol (PROH) + 0.5 M sucrose, using 'Cryotop' or 'thin plastic sticker', respectively. The oocyte survival rates after vitrifying-warming, and the capacity for fertilization and embryonic development were examined in vitro. The rate of embryonic development to blastocyst was significantly higher (P<0.05) in the oocytes vitrified with 15% (v/v) EG + 15% (v/v) PROH + 0.5 M sucrose than in the oocytes vitrified with 15% (v/v) EG + 15% (v/v) DMSO + 0.5 M sucrose (7.4% ± 4.1 vs. 1.7% ± 3.0, respectively). Oocytes vitrified without cumulus cells had a higher survival rate after thawing and a superior embryonic developmental capacity compared with oocytes vitrified with cumulus cells. Prolonged pre-incubation time after thawing adversely affected the rates of embryonic cleavage and development. These results indicate that in vitro matured bovine oocytes can be vitrified successfully with the mixture of the cryoprotectants, EG + PROH, the absence of cumulus cells for vitrification does not affect oocyte survival rate after warming, and vitrified and warmed oocytes do not require pre-incubation before in vitro fertilization.

After more than 2 decades of development in mammalian models and the clinical focus of a few pioneering laboratories, vitrification of human oocytes and embryos has transformed today's assisted reproductive technology (ART) industry. Our ability to cryopreserve gametes and embryos without fear of the damaging effects of ice formation has instilled great confidence in post-warming specimen viability. In turn, clinical treatment options are progressively eliminating fresh embryo transfer (ET; ie, freeze-all cycles), integrating preimplantation genetic screening and contemplating the use of cryopreserved oocytes as a viable resource. Vitrification's impact on clinical treatments is akin to the advent of sperm injection technology in the 1990s on male factor infertility. An appreciable and quantifiable difference was made, with procedural efficacy and global reliability essentially being guaranteed. Yet, there are challenges in the current trends and perspectives in how this technology is and will be optimized in the future. User variation in vitrification products and procedures warrants stricter adherence to quality control measures to enhance specimen biosafety and patient satisfaction, while reducing potential liability concerns. Furthermore, future progress in our understanding of the chemical and cryophysical processes of vitrification will insure the effective cryostorage of reproductive tissues and gametes at a level attained for embryo cryopreservation today.

“…Since the first successful pregnancy using a frozen human oocyte was reported, CRF has been applied with varying success [17][18][19][20][21][22][23][24][25][26][27]. The combination of CRF and intracytoplasmic sperm injection (ICSI) have increased pregnancy rates per cycle to approximately 25% [28,29].…”

To preserve the fertility of patients who undergo chemotherapy and/or radiotherapy, procedures for cryopreservation of female germ cells have been investigated. Cyropreservation methods differ according to follicle stage because the mammalian ovary contains a large number of oocytes at different growth stages. Follicles at very early stages, for example the primordial and primary stages, are usually cryopreserved within ovarian cortical tissue because they need surrounding somatic cells for subsequent development. In contrast, fully-grown oocytes in Graafian follicles are cryopreserved without any other cells at the metaphase II stage. Recently, ultra-rapid cooling was incorporated into cryopreservation procedures for human ovaries. In this review, we describe oocyte freezing, the development of ultra-rapid cooling systems for ovarian tissues, freezing of human ovaries, and ovarian transplantation.
