Difference Between Surrogacy and Egg Donation

Egg donation and surrogacy are both aspects involving third parties to create life.

Egg donors remain completely anonymous, whilst surrogate mothers enter a formal contract and have a relationship with their commissioning parents.

Age Cut Off:
Egg donors may contribute to the maximim age of 34, whilst surrogate mothers can help up to age 50.

Previous Children:
Surrogate mothers are requried to have had one live child before proceeding.  The is no need for egg donors to have had any children.

Contractual Arrangements:
No formal contract is ratified between recipients and egg donors.  The surrogate mother and commissioning parent sign a formal contract which is approved by the High Court before any embryo transfer may take place.

Egg donors do not become pregnant at all.  Surrogate mothers carry the pregnancy for their commissioning parents.

Egg donors are offered a fixed donation.  Surrogate mothers may not be paid.  They can be reimbursed for loss of income and expenses associated with the surrogacy pregnancy.

Menstrual Cycles:
Egg donors need to have regular menstrual cycles (unless these are impacted by their specific contraceptives).  Surrogate mothers can be in full menopause, but need a healthy uterus.

Egg donors contribute their genetics to the recipient.  Surrogate mothers carry the pregnancy and contribute no human tissue to the conception.

Both egg donors and surrogates require a psychological assessment to proceed.  For surrogacy, this assessment is much more extensive and requires the approval of a judge.
