When the intended parents because of some reasons cannot make a genetical contribution into production of their future child and at the same time wouldn’t like their children to bear genetical information from the surrogate mother, they can apply to sperm or egg donors. The sperm donation is known to exist for hundreds of years, but the egg donation was used for the first time not so long ago. During the donation the egg donor undergoes examining and hormone therapy (usually injections) for a long time which help her ovaries produce more than one egg, usually their amount extracted during a surgical operations is between one and fifteen. After careful tests for quality the eggs are usually frozen to be used in future or mixed with sperm.
 Eight cell or blastocysts (past 8 cell stage) are examined from several hours to five days. Embryos with the highest chances to survive are put into the surrogate mother's womb who is also undergoing special treatment to increase the chances of the embryos bonding to the uterus' lining and growing into a fetus. The remaining embryos are destroyed or frozen to be used in later attempts or used by an infertile couple. The embryos which do not begin to grow stop multiplying on the cellular level and leave the body usually imperceptibly. The outcome of one third of all IVF operations result in triplets as super twin pregnancies often result in premature birth. Such children usually have low birth weight and together with some common medical issues connected to bigger quantity of birth many couples of intended parents face the problem of decision not only how many embryos to transfer but also what to do with the remaining ones and whether to conduct a selective reduction to increase the chances of survival for the other fetus(es). The issues of involving an egg donor make gestational surrogacy a disputable question. The disarrays may appear in some hospitals after the birth because hospitals are inclined to define parents by genetics but it is impossible to do that when you have a birth mother who is not genetically related, intended parents who are not genetically related and no present egg or sperm donor.
The process of choosing and egg donor is similar to choosing a surrogate only the great attention should be paid to her genetic aspect more than her lifestyle and communications styles. You can find egg donors as well as surrogates online, through word of mouth, through your R.E. and through agencies. Many agencies offer the services of donation of frozen eggs of their own donors waiting for host wombs and the others have agreements with women ready to become surrogate mothers.
The possibility of having a genetically perfect child with a near guaranteed high IQ and perfect appearance may stun you at first, but in the process of search for a match you’ll understand that the main point isn’t in finding an ideal genetic make-up, it’s in finding someone who just feels right. You can find a person with interests similar to yours hoping your introvert partner and yourself don't end up with an extrovert child or you can find a donor bearing an exterior resemblance to you.
