Sperm banks

What rules should govern sperm banks? Donors may desire anonymity, but children conceived with donated sperm may seek to learn about their biological fathers, and both the children and society in general has an interest in preventing unintentional marriage of half siblings.

Haaretz reports Health Ministry preparing new regulations for Israeli sperm banks

"The regulations will require more detailed family histories from donors and those seeking a donation; limit the number of possible children from each donor; restrict donors to using just one sperm bank; and ban the practice of sperm mixing (in which more than one person's sperm is used).

""Israel has had 15 sperm banks, 13 of them public and two private, but only seven are still active. Sperm samples are not included among the standard healthcare services and the prices of imported sperm samples can cost hundreds of dollars (up to five times more expensive than sperm frozen in the country ). Despite the price gap sperm imports have been on the rise, especially for religious women, who have been advised by their rabbis to get a donation from abroad to avoid the slightest risk of unintentional incest."
