New Research Shows You Can Grow Sperm In a Dish (sciencemag.org)

sciencehabit writes: How the male body produces sperm has long been hidden inside its genitalia. Trying to recreate the process in a lab for humans and other mammals has led to many failures - sperm development appeared to be dependent on unique conditions in the testes. But a new technique may finally be bringing that process into the open. A team of Chinese researchers reports turning a dish of a certain type of mouse stem cell into spermlike cells, which were then used to fertilize eggs and produce healthy mouse pups. The approach could help researchers study mammalian sperm development more directly, and it could spur efforts to develop treatments for male infertility in people.

    A few years of unsuccessfully trying to have a baby would change your opinion and attitude on the subject.

    It's just hormones pumped into your body by your genes who want to replicate. Since we know that, you can easily overcome the need, since it's not _you_ wanting this unpaid job for decades.

    Oh? Does it solve violence against men from women? Go back to your anonymous hole.

    The 3rd-wave feminists need men urgently as the suppressed class that works for them and fulfills all their needs. As none of them have any actual skills besides grandstanding and claiming to be victims and bossing others around, they would just die on their own, like any other parasitic life-form.

    Of course, they do not want to pay with sex for all that either, so I really do not see why they are opposed to sex-bots and porn in the first place. May just be a result of general stupidity and inability to connect causes and effects.

    Just wait until the women who've used this realize that there's nobody around for them to stick with child support.

    A few successes might change yours.
