The Measure of an Egg Donor Agency

The Measure of an Egg Donor Agency How should one measure the success of an egg donor agency? On the face of it one might say, “Well, it must be the number of pregnancies achieved!” “Is it?” Is the number of pregnancies achieved not the result of more factors than an egg donor agency can take credit for? After all, the fertility clinic and doctors and their treatment prescribed, the age of the donor and her fertility screening, the quality and quantity of the sperm used to fertilise, the ability of the uterus to facilitate the growth of the embryo. These are all factors that must be optimal in order to achieve pregnancy. The fact is that all egg donor agencies are governed by certain criteria that ensure donors are viable as fertile egg donors. These factors include egg donors being between the ages of 18 and 35, having a certain and optimal BMI and being screened before an egg donation cycle is undertaken. These factors result in all agencies being created equal as regards the ac

Egg Donation - A Happy Ending

Egg Donation - A Happy Ending For those women whose “partners look at them and they fall pregnant” the use of donor eggs may seem completely absurd. It’s a case of “If you have never walked in someone’s shoes don’t judge them,” and often it’s a complete ignorance, as is the case when you are dealing with a choice you would never have to make. The reality is that, for those increasing woman who, without the use of donor eggs would never be able to experience motherhood, egg donation is the greatest gift of life. The need for donor eggs is on the increase, as infertility becomes a widespread in a sentence that does not discriminate. Our fast paced lifestyles; stress, cancer and delaying having children are all factors that can result in a woman’s ovaries not functioning to produce viable eggs for fertilisation. For these woman an egg donor is a last resort and a gift of life. The world of fertility brings fulfillment and joy to couples via egg donation, or surrogacy. In South Africa we a

Babies via egg donation & the importance of the birth mother

Babies via egg donation & the importance of the birth mother Epigenetics is a new (well to some of us!) buzzword in the field of egg donation for conception. Essentially Epigenetics refers to factors outside the gene, such as a cell's exposure to hormones or genetic variations that can modify a gene. Such factors can change what is ultimately expressed; they can change a phenotype i.e.: they can alter what an organism looks like as a consequence of the interaction of its gene AND the environment. In terms of conception via egg donation that environment begins with the womb of the birth mother. Some examples include hormone and reproductive factors in a woman that may influence the chances of breast and ovarian cancer. These factors are believed to be linked to a woman's exposure to estrogen and progesterone and their effects on cell differentiation in the breast that occur during pregnancy. Conventional science has historically linked cell behaviour to the genes present. La
