Religious views
Some Christian leaders indicate that IVF is acceptable (provided that no fertilized embryos are discarded in the process). Many Christian couples who cannot have children thus can go for IVF, with both the husbands sperm and the wifes egg and this is in line with the churchs teaching. However the issue is more problematic with donor eggs. There are also some Christian leaders (especially Catholic) who are concerned about all in vitro fertility therapies because they disrupt the natural act of conceiving a child where gamete donations, both egg and sperm donations, are seen to "compromise the marital bond and family integrity". and they encourage infertile couples to consider adoption instead. In the Orthodox Jewish community there is no consensus as to whether an egg donor needs to be Jewish in order for the child to be considered Jewish from birth. In the 1990s religious authorities said that if the birth mother was Jewish that the child would be Jewish as well, but in the past few years rabbis in Israel have begun to reconsider, which in turn is causing more debate around the world. Conservative Rabbi Elliot Dorff has suggested that there are arguments for both sides (birth mother or genetic mother) in religious scripture. Dean of the Center for the Jewish Future at Yeshiva University believes that any child where the birth mother or the genetic mother isnt Jewish should go through a conversion process in infancy, to be sure that their Judaism isnt questioned later in life.
Many women have none of these issues, but continue to be unsuccessful using their own eggs—in other words, they have undiagnosed infertility—and thus turn to donor eggs or donor embryos. As stated above, egg donation is also helpful for gay male couples using surrogacy (see LGBT parenting). In the US and UK, if desired (and if the egg donor agrees), the couple can meet and get acquainted with the egg donor, her children and family members. More often, egg donations are anonymous or semi-anonymous (i.e. the egg donor may provide personal and medical information, photographs of herself and/or family members, and an email or third party willing to convey communications between the donor and recipients). In some countries, the law requires non-anonymity (e.g., the UK). In other countries, the law requires anonymity (e.g., France, Spain, the Czech Republic, South Africa). In the US the choice between anonymity, semi-anonymity and non-anonymity is made by the donor and recipient, although some IVF clinics that maintain their own databases of egg donors strongly encourage or require anonymity.

Types of donors
Donors includes the following types:

Donors unrelated to the recipients who do it for altruistic and/or monetary reasons. In the US they are anonymous donors or semi-anonymous donors recruited by egg donor agencies or IVF clinics. Such donors may also be non-anonymous donors, i.e., they may exchange identifying and contact information with the recipients.
