Reproductive Organ Preservation

Reproductive Organ Preservation

CellStor freezing bags are useful in cryo-preserving cells and tissues from reproductive organs such as oocytes, sperm, testicular, and ovarian tissues for treating infertility. Zygotes stored at low temperatures can be used for in-vitro fertilization.

CellBios provides CellStor Straws, CellStor GMP Vials and CellStor bags to preserve embryos, testicular tissues, semen, ovarian tissues and oocytes.


Embryo develops from a zygote in the early stages of multicellular diploid eukaryotic organism. Zygote develops from the fertilization of female egg cell by male sperm cell. Embryos are grown in artificial medium in in-vitro fertilization.

Testicular Tissue Freezing

Cryopreservation of testicular tissue is done for prepubertal patients who are not producing sperm and not able to store a semen sample. It is rare and no spermatogenic recovery has been reported yet, but many methods are in research for storing testicular tissue to restore fertility and produce sperm.


Sperm banking is a procedure to preserve sperm cells and used more successfully after cryopreservation. Reports shown that the sperm cells can be successfully stored till 24 years. Sperm donations are done to preserve male’s fertility especially who are undergoing vasectomy or treatments like chemotherapy and radiation therapy. Glycerol is the common cryoprotectant for semen preservation.

Ovarian Tissue

Ovarian tissue taken out of the body and cryopreserved for future use. A part or whole ovary is removed surgically by laparoscopy. Ovarian cortex is cut into small strips and frozen. Ovarian tissue freezing is mostly performed in cancer patients.


Women’s oocytes are cryopreserved due to cancer treatment or social reasons and postpone pregnancy to a later date.
