Therapeutic Donor Insemination (TDI)

What is therapeutic donor insemination?
Therapeutic donor insemination, or TDI as it is often referred to, is the treatment of infertile couples with a male factor problem with the use of anonymous donor sperm. The fertility problems that make TDI a possible option for couples are azoospermia (or the absence of any sperm), oligospermia (or few sperm) and a male that may carry a genetic disorder and could pass this on to his offspring.

What is the history of TDI?
This procedure has been used since the fourteenth century. Presently, thousands of babies are conceived yearly by this method of treatment.

The legal status of the child born following TDI is still undetermined, but it is generally agreed that children have legitimate status whenever the procedure is done by a physician with the consent of the couple in writing.

Donors, who are they?
The donors are usually males between the ages of 20 and 40 who have a desire to donate their sperm for altruistic reasons.

Care is taken to limit the number of pregnancies from any one donor to a total of ten. The program is totally anonymous. Donors do not receive any information as to the outcome of the sperm donation.

What criteria are used to screen the donors?
Each donor is carefully screened according to the Canadian Fertility and Andrology Society recommendations. They must be free from all communicable diseases and have a clean medical and psychosocial history. The donor's semen count must meet certain criteria prior to acceptance into the program. The screening process is so rigorous that only one-third of the donors that apply for acceptance into the program actually become donors.
Why is frozen sperm used?
Under no circumstances is it recommended that fresh sperm be used. This is because of the possible transmission of the HIV virus through fresh sperm. Freezing the sperm allows the sperm to be frozen while the donor is undergoing repeated screening tests, such as the blood test for the HIV virus. As the AIDS virus is spread through semen, the donors are screened carefully and regularly. All semen that has been saved and frozen is only used after it is quarantined for at least six months and all testing is completed and normal.
What are the risks and problems of TDI?
fertility button Disease: As previously outlined, the donor is carefully screened for disease. However, it is possible that disease may not be detected by testing methods available to us.
fertility button Genetic abnormalities: The genetic or family background of the donor is screened, but it must be understood by couples receiving TDI that abnormalities may occur as in any pregnancy.
fertility button No pregnancy: There is no guarantee that a woman will become pregnant with the use of donor sperm. If after six months of treatment the woman is not pregnant, an appointment should be made to discuss this with the physician.

What is involved for a couple wishing TDI?
Both partners in the relationship must be fully informed about the procedure and be willing to sign a legal consent before treatment is started.

As an active patient, the female will call the clinic to book her inseminations according to her predicted ovulation.

If you do not keep or fail to cancel an insemination that has been booked, you will be charged for the specimen which was prepared for you.
