Ericsson method
Ericsson method
The Ericsson method (pronounced: /ˈɛrɪksən ˈmɛθəd/) is a technique used in assisted reproductive technology to enhance the chances of conceiving a child of a desired sex. It was developed by Dr. Ronald Ericsson in the 1970s.
Etymology
The term "Ericsson method" is named after its developer, Dr. Ronald Ericsson, a prominent biologist and researcher in the field of reproductive medicine.
Description
The Ericsson method is based on the principle that sperm carrying the Y chromosome (which leads to a male child) are lighter and swim faster than sperm carrying the X chromosome (which leads to a female child). In this method, a sperm sample is placed in a tube with a specially prepared liquid and then centrifuged. The faster-swimming Y sperm tend to end up at the top of the tube, while the slower X sperm sink to the bottom. The sperm from the desired layer can then be used for artificial insemination or in vitro fertilization.
