Can women make sperm?

__UPDATE__: All my speculations are likely to be not possible. There are parts of the Y chromosome essential for spermatogenesis. So what I speculate is fiction.

Men are obsolete. They are not needed anymore to sustain life on this planet. Sounds science fiction?

No, I am not talking about cloning, and making exact replicas. I am talking about women making sperms with an X chromosomes so they could reproduce and make more females. The sperm could be from one woman and the egg from a different one.

We are not there yet but the BBC has [this story|http://news.bbc.co.uk/2/hi/health/6547675.stm#graphic]:
;: ''Scientists say they have successfully made immature sperm cells from human bone marrow samples.''

;: ''If these can be grown into fully developed sperm, which the researchers hope to do within five years, they may be useful in fertility treatments.''

...

;: ''The researchers from the Universities of Göttingen and Münster and the Medical School of Hannover isolated adult stem cells - cells that have the ability to become many types of tissue in the body - from bone marrow samples taken from male volunteers.''

They took the bone marrow samples from __male__ volunteers. I wonder was the decision because only male stem cells can differentiate to spermatogonia (if spermatogenesis is entirely or partly coded on the Y chromosome) or it was a political move. Taking samples from males and ''females'' may extend the ban from the use of artificial sperm in reproduction clinics (technically no one is there yet), on to this line of research completely. Despite its importance for many people:

So not to sound sensationalist and an alarmist. This is still very early and there is no proof that mature sperms (if produced) are of good enough quality and biologically stable.

2 yaers ago i read an article about our possible exticrion
and how our species is doomed because of the many increasing defects of the y chromosome
i remember the writer ending the article by saying that if we want to survive then it's about time we consider a future with out men, and start researching means of making that possible

mesh 2oltelko ento day3een:)

but do you think that if men are extinct, wars will be over and humans (the remaining ones) will not suffer ? do you think that men are the roots of all evil ?

No ofcourse not
i never said that
We humans are the biggest source of evil irrespective of the gender, i was talking from a biological aspect, the male gender has a higher risk of genetic defects
that's all

women get diseases too, they probably get more diseases that are not directly linked to diseased genes.

enta hatganeny??!
i know all this i was talking about Genetic defects ONLY
the y chromosomes has very little means -if any- to correct or minimize errors occuring during replication
I know we the females get alot of diseases
i know we are the gender that has PMS
