Why Medical Screening Matters
Every egg donor in Canada undergoes comprehensive medical screening in accordance with Health Canada regulations. These requirements exist to ensure donors are physically and reproductively healthy enough to undergo ovarian stimulation and egg retrieval safely, while also protecting the intended parents and any children conceived through donation.
The Physical Examination
Your screening begins with a thorough physical examination. A fertility doctor will assess your general health, including blood pressure, heart rate, and overall physical condition. A pelvic examination checks your reproductive organs for any abnormalities that could affect the donation process.
This appointment is similar to a standard gynecological check-up. The medical team will also review your personal health history and your family’s medical history spanning at least three generations.
Blood Work and Hormone Testing
Blood tests form a central part of the screening. Several key hormones are measured to assess your ovarian reserve and fertility potential. AMH (anti-Mullerian hormone) indicates how many eggs remain in your ovaries. FSH (follicle-stimulating hormone) shows how hard your body is working to produce eggs. Estradiol levels provide additional information about ovarian function.
These results help the medical team predict how well you’ll respond to stimulation medications and approximately how many eggs might be retrieved. Normal hormone levels don’t guarantee a specific outcome, but they’re strong indicators of donation potential.
Infectious Disease Testing
You’ll be tested for a range of infectious diseases as required by Health Canada. This includes HIV, Hepatitis B and C, syphilis (RPR), cytomegalovirus (CMV), and cervical cultures for gonorrhea and chlamydia. These tests protect everyone involved in the process and are standard across all fertility clinics in Canada.
Transvaginal Ultrasound
A transvaginal ultrasound allows the doctor to visualize your ovaries and count the antral follicles present. Each follicle has the potential to contain an egg. A higher antral follicle count generally suggests a better response to stimulation medications and a greater number of eggs at retrieval.
The ultrasound is a brief, minimally uncomfortable procedure. It provides the fertility team with essential information for planning your stimulation protocol.
Genetic Carrier Screening
Comprehensive genetic carrier screening tests your DNA for variants associated with hundreds of recessive and X-linked conditions. At Fertility Match, we require expanded carrier screening to ensure genetic compatibility between the donor and sperm provider.
Common conditions screened include cystic fibrosis, spinal muscular atrophy, Tay-Sachs disease, sickle cell disease, and thalassemia. Being identified as a carrier for one or more conditions is common and usually does not prevent you from donating. The critical factor is ensuring the sperm provider isn’t a carrier for the same condition.
Psychological Evaluation
While not a medical test in the traditional sense, the psychological evaluation is a mandatory part of screening. You’ll meet with a fertility counsellor or psychologist experienced in third-party reproduction. This session explores your motivations for donating, your emotional readiness, your understanding of the process, and your feelings about potential future contact with donor-conceived children.
The counselling session typically lasts about 90 minutes and may include a follow-up. It’s designed to support you, not to judge you. Learn more about the role of counselling in egg donation.
Toxicology Screening
A urine test screens for recreational drugs. Donors must be free from all recreational substances, as drug use can affect egg quality and the safety of the retrieval procedure. This is a standard requirement across all Canadian egg donation programs.
Timeline for Screening
The complete screening process typically takes two to four weeks, depending on appointment availability and how quickly results are returned. Some tests, like genetic carrier screening, may take longer to process. Your fertility consultant will coordinate scheduling and keep you informed at every stage.
What Happens After Screening
Once all screening is complete and you’ve been cleared, your profile becomes active in the egg donor database. Intended parents can then review your profile and select you as their donor. From there, legal agreements are signed, and the medical phase of the donation cycle begins.
