The Ericsson method is one of the very few metods of gender selection that are still available in the US and several other countries around the world though many experts feel that this method is not as successful to select the gender of a child as previously reported. It has a success rate around 70-75%. It is one the lower end medically assisted gender selection techniques and therefore this is reflected in the price. There is no costly IVF procedure to pay for.
Day of Insemination
The Ericsson method is is carried out on the day that the mother is expected to ovulate amd involves separation of X and Y sperms and artificial insemination. So careful tracking of the monthly cycle is highly advisable. No in-vitro fertilization is needed.
The Ericsson method relies on the fact that male and female sperm act in totally different ways. Male sperm are faster swimmers, but although the females are slower they are much more resiliant and should live for longer.
On the morning of expected ovulation, the mother and father will go to a clinic where the father will then provide a sample of the ejaculate. If the parents have chosen to have a baby girl, the mother will also take clomid to aid the process of conceiving a female gender baby.
Step 2: Test tube separation of X and Y sperm
The sperm are placed into a test tube along with a substance called albumin in increasingly thickened layers. The sperm will then swim their way down through the different layers. Working on the principle that only the fastest sperm will make it to the bottom.
The selected sperm is then artificially inseminated into the mother where conception should hopefully take place.
The success rates of the Ericsson (albumin) method are more favourable for parents wanting to conceive a boy, with the success rate reaching around 75%. Whereas parents wanting a girl may find a success rate of around 70-72%.
About 25% of parents who get a different sex then the one they chose.
