Mouse Sperm Cells Grown In Vitro 121

smitty777 writes "In what is being hailed as a breakthrough in male infertility, researchers from Muenster and Ben Gurion Universities were able to actually grow mouse sperm cells in a petri dish. Researchers feel this is just a short step away from human in vitro sperm cell production. The details of how this will be accomplished are still being worked out. FTA: '[According to Professor Richard Sharpe], "What this research shows is that it will be possible to make human sperm outside the body. The germ cells just need the right environment. That's the tricky part getting them to think they are in the testes." Professor Sharpe believes that one novel way may make.it possible. He proposes using a live mouse as a "host" to make human sperm. He said: "What you would do is take some human testicular tissue with germ cells and place that under the skin of the mouse and use it to incubate the cells. You could then extract any sperm and use it in fertility treatment. But we would have to demonstrate that there were no mouse cells present in the extracted sperm if we were to use this technique and I believe that's possible."'"

    I didn't mean to imply life was a wonderful paradise for them or that they didn't sacrifice, just that men have done a large part of the interface work with reality required to maintain a civilization...most of (but not all) the big picture stuff. yes women bore and raised the offspring (which is critical obviously), prepared food, and handled part of the home maintenance, but right along side that were the men defending their existence, building the homes, hunting/working for the food that was prepared, solving life's bigger calamities when they occurred, advancing the quality of life with creative invention/science, and were the first ones to sacrifice their lives for their families. This, to a lesser degree, is still true today, except that men are no longer respected for it, and while feminine attributes/role takeovers are celebrated to the point of absurdity, masculine ones are increasingly censured, often starting in kindergarten.

    Through my life, in situations where I hear women talking, especially when they don't realize I'm listening, their use of the language makes their self centered attitudes towards men come out loud and clear. the things they say make me conclude that they're just unaware of the work that goes into maintaining a society such as ours. they seem to think nothing else is relevant to this goal other than their own (usually immediate) needs and that men who aren't feminist doormats obstruct their satiation and advancement. I would expect this from people who've grown used to a chattel role or have just experienced no other, which is why I thought it might be due to natural instinct run rampant by modern feminism. women just aren't taught to respect the value men bring to the table anymore. men of course are being taught to be the aforementioned doormats.

    In terms of this topic, I think artificial sperm culturing would give this already overdominant anti-male trend even more steam. Women have been taught to think they could be 100% self reliant if only men would 'let them'. From what I've seen, it's a lot more complicated than that, but, men, instinctively being the providers, gave them the next best thing: a doublethink fantasy.

    I think one worry from this type of technique would be the inclusion of murine virion DNA. For example, the likely source of XMRV was due to infection of human cells passaged through mice (that's my understanding of the cause). No one wants to accidentally create a new retrovirus ...

    the statement is based on behavioral trends. when the going gets tough, most women will defer to, instinctively, and/or manipulate an available man into doing the task. viewing examples of this ubiquity is easy. if you want the cultural reflection of current norms and trends, turn on the tv, and if you want realtime sampling, go to a public place where people interact and pay attention. there is a nasty double standard brewing in the culture that is detrimental to men and boys and it is quite obvious, even in irrelevancies like television commercials. it is a biological fact that women are not as strong as men physically, while mentally, the genders differ in temperament and focus. men tend to be world focused, while women tend to be people focused. these are biases, not absolutes, but they should be encouraged, not censured for the sake of some politically charged ideology.

    anyway, based on what I've seen and read, women have shown better small motor dexterity than most men, though there are exceptions. in terms of overall capabilities, the male performance curve slopes much more than the female.. ie the majority of geniuses are men as are the majority of retarded people. fewer women suffer neurological and physical disability than men. it looks like men are nature's 'gamble.' they serve the species by being the differentiators who advertise latent talent, while the women choose which qualities they like when they make their sexual selections. except in the most cerebral of people, most of this is done nonverbally and subconciously by both genders regardless of what political think-tank 'theories' state.

    also my comment didn't just imply physical labor.. by 'dirty work' I meant any time a serious effort was needed that does not (usually) get the spotlight when it comes time for the reward.
