How Can People Preserve Gametes?

Cryopreservation of Human Gametes

Alongside with semen freezing, cryopreservation is one of the key components in ART. “Surplus” oocytes obtained from a single collection can be stored for later use. Thus, reducing the costs and risks of hormone stimulations associated with multiple oocyte collections.

Vitrification of Human Oocytes

Vitrification (ultrafast freezing) of human oocytes represents a breakthrough in the reproductive sciences and the practice of assisted reproductive medicine. Since the main damaging factor for human egg cells in the freeze-thaw process is the formation of ice crystals, it does not happen during vitrification of human egg cells. Substances simply become amorphous without the formation of ice crystals, which minimizes the likelihood of human egg cell damage.

Cryopreservation of Sperm

The limited life span of human spermatozoa requires strict coordination of simultaneous formation of both sperm and oocytes, which in some cases may be inconvenient or even impossible. For this reason, some valuable studies have been conducted to prolong the life span of sperm by cooling cells. In 1953, the first woman’s healthy pregnancy was reported as a result of the use of cryopreserved human sperm.

Aim of Sperm Cryopreservation

There are both medical and social reasons for sperm cryopreservation: absence of a partner in a day of fertilization during egg fertilization; individual variability in sperm quality; fertility preservation in men: vasectomy, radiation therapy, or treatment with cytotoxic drugs; upcoming surgical interventions on the testicles; preventing the transmission of diseases through semen; inability to get fresh ejaculate in a day of oocyte puncture; donor sperm bank creation.
