The most sought-after donors tend to be those who are (1) proven (i.e., have donated before and produced a pregnancy from it, proving themselves both fertile and reliable); (2) conventionally attractive; (3) healthy, with good family health histories; and (4) smart, well educated. Donor profiles presented on agency websites are their primary marketing tool to find recipients and learn what these future consumers want. On the donor profiles listed on the agency website for recipients, or "clients", to peruse for their desired egg match, "physical characteristics, family health history, educational attainment (in some cases, standardized test scores, GPA, and IQ scores are requested), as well as open-ended questions about hobbies, likes and dislikes, and motivations for donating" are included. Donors are encouraged to submit attractive photos and are advised of what the recipient finds as desirable. Profiles that are at some point deemed unacceptable are deleted, whether it be because their personalities did not stand out or their portrayals were viewed as negative in some way. Overweight volunteers for donation are also most often not accepted, not just because of conventional views on physical attractiveness but also because women with a higher body-mass index tend to respond differently (less well) to ovarian stimulation drugs and IVF clinics thus generally recommend that patients not use donors with higher BMIs. Egg donors also have a higher standard of physical appearance than sperm donors; many sperm donors are not required to provide adult photographs of themselves, or in some cases, any photographs.
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.
