Reproductive Biology

The self-preservation of spermatozoa is proposed before any treatment presenting a risk of leading to a transient or definitive alteration of male fertility. A collection of sperm by masturbation is proposed as first intention. In some cases, surgical removal by testicular biopsy is also possible.

The spermatozoa are stored in liquid nitrogen at -196°C and can be stored indefinitely until the age of 60 , the maximum authorized by law to use these gametes in the context of Medical Assistance. to Procreation.

Fertility preservation is indicated in various medical situations , including pathologies such as cancer, inflammatory or hematological diseases, surgical procedures that may alter sexual or reproductive function or in the context of a gender transition. It is also possible outside medical indication from 29 to 45 years old. In this case, the annual storage costs are not covered by social security.

Preservation of female fertility is proposed before any treatment presenting a risk of causing a temporary or permanent impairment of fertility in women. The self-preservation of oocytes by ovarian puncture ovarian stimulation treatment is the reference technique. In some cases, surgical removal to preserve ovarian tissue is also possible.

Oocytes or ovarian tissue are stored in liquid nitrogen at -196°C and can be stored indefinitely up to the age of 45 , the maximum authorized by law for use in the context of medically assisted procreation or an autograft.

Fertility preservation is indicated in various medical situations , including pathologies such as cancer, inflammatory or hematological diseases, surgical procedures on the ovaries that may alter reproductive function or in the context of a gender transition. It is also possible without medical indication from 29 to 37 years old. In this case, the annual storage costs are not covered by social security.

Fertility preservation is also possible in children in the context of certain pathologies.

In the boy before puberty , there are no sperm. Preservation of testicular tissue is possible before a treatment with a high risk of causing permanent sterility, but no technique has yet been developed to allow the use of this tissue at the present time. In adolescents , it is possible to consider ejaculated or surgically removed spermatozoa

In girls before puberty , preservation of ovarian tissue is possible before treatment at high risk of causing permanent sterility for subsequent autograft In adolescents, the freezing of ovarian tissue or oocytes by ovarian puncture after ovarian stimulation treatment is discussed on a case-by-case basis depending on the pathologies, age and maturity of the girls.
