New Genetic Causes of Male Infertility Discovered
Dr. Pastuszac at Baylor College of Medicine has discovered two new genetic causes of male infertility. There was one previous gene deletion noted on the Y chromosome. Previously, the Y-chromosome microdeletion and major chromosomal errors were known to cause severe male factor infertility. The frequency of either of these is under 5 percent of infertile […]
Gender Selection and the History of Preimplantation Genetic Testing (and 3 Myths about Gender Selection)
Genetic testing to screen out defective embryos before implantation in IVF also reveals gender, giving parents a choice to do gender selection. History of gender selection Preimplantation genetic testing was initially developed in England in 1990 to detect single-gene and sex-chromosome linked diseases in at-risk couples. The test then was adapted as part of in vitro […]
