Possibly: Requires help from a suitable fertility clinic. Men with klinfelter's and a normal serum testosterone (st) have a high rate of successful sperm extraction by testicular microdissection. Some men with lower st may respond to HCG stimulation to elevate st and have reasonable sperm retrieval. Then successful invitro fertilization or intracytoplasmic sperm injection techniques are required for success. ...Read more

Is klinefelter's syndrome dominent or recessive?

Is klinefelter's syndrome dominent or recessive?

Error in formation: Humans have 23 pairs of chromosomes. During the formation of the egg, each pair splits and one of each travels to the egg. At conception, the sperm brings 22 + an X or Y & the new embryo now has 23 pairs (two of each). In Kleinfelter, the egg retains 2 X chromosomes instead of 1 & the sperm brings a Y.The fetus then has 23 pairs + the extra X. This is an error in formation, not an inherited trait ...Read more
