Gender Selection
Some sperm banks enable recipients to choose the gender of their child. Although the methods used do not guarantee 100% success, the chances of being able to select the gender of a child are held to be considerably increased.
One of the processes used is the 'swim up' method, whereby a sperm extender is added to the donor's freshly ejaculated sperm and the test-tube is left to settle. After about half-an-hour, the lighter Y chromosome sperm will have swum to the top, leaving the heavier 'x' chromosome sperm at the bottom, thus allowing selection and storage according to gender.
The alternative process is the Percoll Method which is similar to the 'swim up' method but involves additionally the centrifuging of the sperm in a similar way to the washing of samples produced for IUI inseminations, or for IVF purposes.
Gender selection is not permitted in a number of countries, including the UK.

Famous quotes containing the words gender and/or selection:
“Most women of [the WW II] generation have but one image of good motherhood—the one their mothers embodied. . . . Anything done “for the sake of the children” justified, even ennobled the mother’s role. Motherhood was tantamount to martyrdom during that unique era when children were gods. Those who appeared to put their own needs first were castigated and shunned—the ultimate damnation for a gender trained to be wholly dependent on the acceptance and praise of others.”
—Melinda M. Marshall (20th century)
“Judge Ginsburg’s selection should be a model—chosen on merit and not ideology, despite some naysaying, with little advance publicity. Her treatment could begin to overturn a terrible precedent: that is, that the most terrifying sentence among the accomplished in America has become, “Honey—the White House is on the phone.””
—Anna Quindlen (b. 1952)
