I need a sperm donor

I am a single mother who wishes to have a baby without any man disturbing me about the baby. I will appreciate it if you can suggest an anonymous sperm donor who must be an intelligent and healthy Nigerian of any age.

Many Teaching Hospitals in the country have Sperm Banks with detailed information about the anonymous sperm donors. I can send you the necessary contacts of the doctors in charge of one of these Teaching Hospitals by private communication.
