The war against red-haired males. [Time.com]
Cryos International, the world’s largest sperm bank, recently announced that it will be turning away redheaded donors at the door. The company’s red-haired sperm supply is full up, and not often called upon. Clinic director Ole Schou told a Danish newspaper that parents are inclined to select donors who are physically similar to themselves, and red’s rareness makes it an unpopular choice.

In Sizing Up Sperm
, people dressed in all white literally act out the role of sperm in the race to become one with the egg, running through valleys, squeezing through spirals, battling Leukocytes and much more. The results are stunning and the program airs this Sunday, March 14 on National Geographic. It just so happens that Slate also got in on the ejaculation meme, and delivered an article on a story of sperm donors and DNA tracing in Are Sperm Donors Really Anonymous Anymore?

Indeed, at 6 million years of separation, the difference in [Y-chromosome] gene content in chimpanzee and human is more comparable to the difference in autosomal gene content in chicken and human, at 310 million years of separation.
It is commonly said that the Human and Chimpanzee genomes share 99% or more identical DNA. In a surprising development about to be published in Nature
, the Y-chromosomes of these two species were found to share only 70% of their DNA, raising important questions about the mode and tempo by which speciation from a common ancestor occurred. This finding may point the finger
at the evolution of different patterns of sperm-competition and mating practices within these two species.

The seller called 'em polkadots.
"When I got the dress, my eyes about popped out of my head. These were NOT creamy white polkadots. My mind raced. This was a novelty print, yes, but not of balloons or cheerfully wriggling tadpoles. There's no way…could it be!? Could the 1950's designer Mark-Robbins been so devious as to devise a blue dress covered—literally covered—in…"

Bizarre child support battle in Brooklyn
A Brooklyn, New York man who stopped paying storage fees for his frozen sperm after divorcing his wife has filed suit against the sperm bank, his ex, and a notary public after learning she picked up the payments and used the sperm to get pregnant. Deon Francois, who now must pay child support, says he didn't want a child and never gave consent for the use of his sperm.

Another reason to practice safe sex?
Man meets woman. Man has oral sex with woman. Woman keeps the sperm, uses it to impregnate herself, then sues for child support. Man counter-sues for emotional distress and "sperm theft". Although the emotional distress claim is still active, the "sperm theft" claim was dismissed. On that point, the court decided:
When plaintiff "delivered" his sperm, it was a gift -- an absolute and irrevocable transfer of title to property from a donor to a donee... There was no agreement that the original deposit would be returned upon request.

Beware ... step away from the laptop.
Laptop computers may damage male fertility. Dr. Yefim Sheynkin
of the State University of New York (Stony Brook) reports in the journal Human Reproduction. "Laptops, which reach high internal operating temperatures, can heat up the scrotum which could affect the quality and quantity of men’s sperm." "...Sheynkin, director of male infertility and microsurgery at the university. 'Don't get me wrong -- the laptop computer is very useful and helpful. But we need to be cautious

Phylogeny recapitulates potheads.
Apparently getting stoned affects the behavior of the smoker's sperm. The little guys start out really excited but then burn out before achieving their goals. Why does this sound familiar? Would it be a good ad campaign? Ah, I can't be bothered to figure it out, pass the bong.

Sperm Wars: Extreme sporting's next generation may well be Exo-biotic. What could be first manifestation in this new realm of sport? Taking into account such factors as: simplicity of contest design, ease of sample collection, lots of visible action, and abundant human male competitiveness, the most logical and economic choice would be a sperm competition.
Any volunteers? What do you think the next "extreme" sport will be?

"Jody Has Two Daddies" -- The literal remix.
Scientists are making egg cells now, raising the (eventual) possibility of one guy providing the genetic material to raise a crop of eggs, while the other guy provides the crop of sperm (no extra work necessary). Just add one surrogate mother and there you have it: Yet another fundamentalist nightmare, in cute infant "Adam and Steve" form.

It's all over, boys, we're obsolete
A team of Australian scientists has announced that they've found a way to fertilize human ova with somatic cells instead of sperm. No actual living babies have been produced yet, but they expect results within the year.
