I am a Chinese Sperm donor in Dallas, Texas. I am a physics teacher working in a university and will be stay here within 2016. I am 36 years old and have one beautiful child. If anyone need, please contact me. Prefer AI, and will also consider NI after discussion.
P.S., I have passed all the health examination and donate last year (2014), in a government sperm bank in China. I would like to freely donate for a family in the USA.
