Sperm Sorting and Gender Selection

Sperm sorting is a gender-selection technique that improves a couple's chances of choosing their embryo's sex.  A couple may choose this option to prevent certain genetic diseases or to promote family balancing.  Prior to insemination of the egg, sperm sorting separates X-chromosome (female) sperm from Y-chromosome (male) sperm, both of which determine the sex of the offspring.  This distinguishes sperm sorting from PGD, in which a fertilized embryo is chosen for transferal to the uterus based on its sex.

The sperm sorting technique can also be used to prevent X-linked diseases (such as hemophilia, Duchenne muscular dystrophy, Lesch-Nyhan syndrome, and X-linked mental retardation) that are most often expressed only in male offspring.  By birthing a female child, a couple at risk for X-linked diseases may reduce their offspring's chances of expressing the disease.

The Sperm Sorting Procedure

After a semen sample is collected, a cytometer is used to distinguish the X-chromosomes from the Y-chromosomes.  The desired X- or Y- chromosomes are separated and further analyzed.  Finally, the desired sperm is combined with the egg through artificial insemination or IVF.

Cost of Sperm Sorting

The cost of sperm sorting varies according to the agency a couple uses.  The price generally includes consultation fees; semen collection, freezing, storing, and shipping; IUI cycle monitoring; GIVF and OPK monitoring; and additional fees if a couple uses a surrogate or egg donor.  According to some sources, in 2001, the average couple using MicroSort®, one method of sperm sorting promoted in the U.S., spent nearly $10,000. MicroSort® costs approximately $3,200 a try, and most couples attempt it three times.
