I have a friend who is in a polyamorous relationship. She has 2 husbands. Right now the 3 of them are ttc. We were talking about ttc the other day. She said she had a better chance of ttc because she has 2 partners. I had thought she meant because she was having twice as much sex. She said it wasn't only that. She said that if you have 2 partners the sperm competes and you are more likely to conceive. I had never heard this. I found this interesting so I googled it to try to find some studies or information. I couldn't find anything. Has anyone heard of this? If so can you point me towards some info. online? What are your thoughts? Is this true or not?
