to allow the ‘harvesting’ of ripe eggs. In most cases, a volunteer is<br />

found by the couple who need treatment by egg donation, but the<br />

CRG also tries to encourage healthy young women from outside<br />

the IVF circuit to volunteer as egg donors.<br />

Anonymous or not<br />

A general rule is that the donors are not told who the recipients<br />

will be, and vice-versa. To be sure the new legislation (2007)<br />

concerning assisted fertilization and everything related leaves<br />

open the option for known donation, but nevertheless implies in<br />

the formulation of the rules altogether a marked preference for<br />

anonymity. A specific situation in which this general rule may be<br />

waived is that of egg donation, i.e. if the recipient couple explicitly<br />

chooses their own egg donor or the donor offers to help a specific<br />

couple. This is known as ‘named donation’.<br />

However, there are also cases where several couples each provide<br />

a donor and the donors are exchanged among the group. This<br />

‘exchange donation’ system allows couples to find donors among<br />

their own families or friends, while still safeguarding the principle<br />

of anonymity. See ‘Named donation versus exchange donation’<br />

p. 103 for the reason why this may be important.<br />

Strict selection and genetic screening<br />

Obviously, not everyone is a suitable donor. All donors need to<br />

undergo rigorous medical screening before they are approved as<br />

donors. For example, a detailed family history is mapped out and<br />

analysed thoroughly to identify recurring characteristics. General<br />

factors such as life expectancy, physical health, mental stability,<br />

etc. are important here.<br />

The preliminary testing procedures include determination of the<br />

donor’s blood group and rhesus factor and the blood is also tested<br />

for the presence of infections such as hepatitis (jaundice) and HIV<br />

(the AIDS virus).<br />

A phenotype profile is compiled of every sperm donor. This involves<br />

the donor’s characteristics, i.e. hair and eye colour, skin colour,<br />

build, etc. When donor sperm is used, great care is always taken<br />

to ensure that the donor’s blood group and as many physical<br />

characteristics as possible match those of the recipient couple.<br />

Unfortunately, this strict phenotype selection is not possible in<br />

cases of egg and embryo donation because the supply of donors is<br />

too limited and the treatment too complex. Furthermore, volunteer<br />

egg and embryo donors can only be recruited from among women<br />

up to the age of 35 years. Exceptions to this rule are only made in<br />

certain cases of named donation and with the recipient couple’s<br />

explicit permission.<br />
