No beneficial effect of preimplantation genetic screening in women of advanced maternal age with a high risk for embryonic aneuploidy (2008)

Twisk, Moniek, Mastenbroek, Sebastiaan, Hoek, Annemieke, Heineman, Maas-Jan, Van Der Veen, Fulco, Bossuyt, Patrick M., ...

BACKGROUND Human preimplantation embryos generated through in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatments show a variable rate of numerical chromosome...

The use of spermHALO-FISH to determine DAZ gene copy number (2003)

Repping, Sjoerd, Korver, Cindy M., Leschot, Nico J., Van Der Veen, Fulco

The AZFc region of the human Y chromosome is frequently deleted in men with spermatogenic failure and contains many multicopy genes. The best‐characterized gene family within this region is the...

Transmission of male infertility to future generations: lessons from the Y chromosome (2002)

Silber, Sherman J., Repping, Sjoerd

The introduction of ICSI and testicular sperm extraction (TESE) has allowed many infertile men to father children. The biggest concern about the wide use of these techniques is the health of the...

PCR Assessment of Chlamydia trachomatis Infection of Semen Specimens Processed for Artificial Insemination

Pannekoek, Yvonne, Westenberg, Steven M., De Vries, Jan, Repping, Sjoerd, Spanjaard, Lodewijk, Eijk, Paul P., ...

In order to ascertain the microbiological quality of stored semen specimens processed for artificial insemination by a donor (AID), we developed a PCR assay targeting the chlamydial plasmid to detect...

Pharmacokinetic Profiles of Nevirapine and Indinavir in Various Fractions of Seminal Plasma

Repping, Sjoerd, Lange, Joep M. A., Hoetelmans, Richard M. W., Prins, Jan M.

Limited data are available on antiretroviral drug concentrations in seminal plasma during a dosing interval. Further, since human ejaculate is composed of fluids originating from the testes, the...

Recombination between Palindromes P5 and P1 on the Human Y Chromosome Causes Massive Deletions and Spermatogenic Failure

Repping, Sjoerd, Skaletsky, Helen, Lange, Julian, Silber, Sherman, Van der Veen, Fulco, Oates, Robert D., ...

It is widely believed that at least three nonoverlapping regions of the human Y chromosome—AZFa, AZFb, and AZFc (“azoospermia factors” a, b, and c)—are essential for normal spermatogenesis....
