A sperm donor who has fathered 49 children worldwide is having his first through IVF.
Kyle Gordy, 30, announced that he is expecting his 50th biological child by donating his 'tadpoles' to IVF for the very first time.
The social media star, from California, USA, recently revealed how he keeps his sperm in 'tip top' shape by eating more protein, including beans and fish.
He is often inundated with messages from women who want to have his child and claimed to have helped a further 12 families to conceive.
Kyle usually offers his sperm for artificial insemination or less commonly by having sex with women – accounting for around one in 10 of donations.
However, his latest donation is the first time that his sperm will be used to fertilise eggs and the resulting embryos will be frozen for a year until the woman is ready to become pregnant.
He was approached by the hopeful mum online who chose him specifically, reported the MailOnline.
Kyle explained: "She could've gone to the sperm bank if she wanted to, but she'd rather do it with me.
"She likes the fact she's able to see me and talk to me, rather than being a random number on a vial."
He added: "Also, the procedure is very expensive, so at least she was able to save some money by getting me to donate for free."
Kyle believes that he was recommended to the woman, who is also a doctor, "through the grapevine" and said he is excited to go through the process and gain an understanding of how it works.
However, it includes several stages that he does not usually complete such as cancerous tests and phone calls.
Kyle had to have an HTLV test for the first time which looks for a virus that can cause leukaemia and lymphoma.
The virus is spread through blood transfusions and sexual contact or by sharing needles and syringes.
He told how he felt it was important for him to do the tests due to his hobby and how the virus can transfer from mother to baby through birth or breast feeding.
After an initial phone consultation, Kyle was told that he had to "do his business" at a hotel before donating to the clinic.
But he did have to pretend that he had been with the woman for three months and that they are having IVF as a gift for her birthday.
The pair are also classed as "in a relationship" in emails and phone calls to avoid extra costs, Kyle explained.
Kyle's sperm and the woman's egg will be fertilised next Wednesday and the resulting embryos will be frozen for a year.
After his first procedure, Kyle plans to follow the process again to help other families in the future with a few women already interested, including a former Playboy playmate.
"I would be happy to do whatever process, as long as it makes people happy and that's what they want. I have no issues," he said.
Kyle's donations have caused problems with women he has dated in the past, who do not always approve.
He believes that many women looking for a relationship do not agree with his hobby, while those who approach him are only interested in having a baby.
"I have accepted my decision to donate sperm but I've realised that my dating may never be the same as it once was," Kyle said.
"If I really like them and we're compatible, I possibly would give it up though."
