Profound teratospermia does not influence sex chromosomal aneuploidy rate in in vitro fertilization–preimplantation genetic diagnosis cycles

Autor: Paul R. Gindoff, Molina B. Dayal, A.K. Dubey, Douglas B. Peak, Shvetha M. Zarek, David Frankfurter

Publikováno v: Fertility and Sterility. 93:666-668

Because spermatocyte meiotic error results in embryonic sex chromosomal aneuploidy, it is speculated that teratospermia correlates with increased embryonic sex chromosomal abnormalities. Our findings contradict this theory, suggesting that morphology

Delayed Puberty and Hypogonadism Caused by Mutations in the Follicle-Stimulating Hormone β-Subunit Gene

Autor: Barbara L. van Lingen, J. Larry Jameson, Kenneth V. Vu, Richard H. Reindollar, Mark R. Gray, Douglas B. Peak, Eun Jig Lee, Anne B. Namnoum, Lawrence C. Layman, Paul G. McDonough

Publikováno v: New England Journal of Medicine. 337:607-611

The pituitary gonadotropins luteinizing hormone and follicle-stimulating hormone (FSH) regulate the production of sex steroids necessary for pubertal development and fertility. Inherited genetic defects that cause hypogonadism have been identified at

The use of lead follicle diameter to initiate gonadotropin-releasing hormone antagonist does not affect in vitro fertilization clinical pregnancy, implantation, or live birth rates: a prospective, randomized study

Autor: Molina B. Dayal, David Frankfurter, Douglas B. Peak, Candice O'Hern, Paul R. Gindoff, A.K. Dubey

Publikováno v: Fertility and sterility. 92(6)

In this prospective, randomized study, waiting for the lead follicle to reach 14 mm before initiating GnRH antagonist administration effectively prevents an LH surge and ovulation during an IVF cycle. Furthermore, delaying GnRH start until the domina
