More Sperm, Live Longer November 27, 2009

Posted by Geekgirl in Health, medical.

While this publication is not related to LGBT research, I was surprised to find this and found it interesting.

To summarize, there is a correlation between the life span of a man and his sperm count. More sperm. Live longer.

If you are wondering if there is a difference in sperm counts between gay men and straight men, I have not come across such research. I’ll let you know if I do.

Good semen quality and life expectancy: a cohort study of 43,277 men. (more…)

Marriage is about Procreation. Part 2.

I made a biological argument against this and planned to write more. Little did I know how easy it would be to prove that Fundamentalists and right wing conservatives believe that marriage is about procreation. This text is copied directly from the Manhattan Declaration. You can Google it. Be sure to notice that one of it’s founders is Chuck Colson.


The impulse to redefine marriage in order to recognize same-sex and multiple partner relationships is a symptom, rather than the cause, of the erosion of the marriage culture. (more…)

Today’s blog is an editorial. As I continue to explore both LGBT research and what is happening in our society, I think that the viewpoint of a biologist can be added to the debate. I speak only for myself. All statistics here are provided by the Guttmacher Institute and Center for Disease Control.

Are you gay because you came from a large, fast swimming sperm?

Here is the question strictly from a biological point of view. If gay males do not procreate, why doesn’t being gay die out? We all know that gay male humans can and do procreate. But gay animals? For the purpose of a biological argument, let’s assume gay males do not procreate.  This has often been called a Darwinian paradox in the research. Biologists answer this question differently from everyday people. The gene(s), or whatever the complex biology is behind being gay, doesn’t die out because there must be some advantage. Make sense? I came across a recent publication that presents a novel prediction in the research on sexual orientation and why being gay doesn’t die out.

Dr. Reed at Harvard presents an interesting correlation and proposes an interesting prediction. Please note. Correlations are NOT proof of a direct cause and effect. Also, a prediction is just that. A theory that is waiting for further experiments. (more…)
