Gonadotrophin-releasing hormone agonists (GnRHa) are routinely used in IVF programmes to prevent an unwanted LH surge and consequent ovulation. Despite its widespread use in IVF, a convincing dose recommendation for GnRHa in IVF does not exist. In ou

Specific gonadotrophin-releasing hormone analogue binding predominantly in human luteinized follicular aspirates and not in human pre-ovulatory follicles

Autor: C.B. Lambalk, M. N. Helder, R.M.J. Janssens, J. de Koning, J. Schoemaker, L. Brus

Publikováno v: Human Reproduction. 12:769-773

In an attempt to resolve the apparent controversy in the observed effects of gonadotrophin-releasing hormone (GnRH) analogues on the ovary, conventional binding studies were conducted with a GnRH agonist and an antagonist in various ovarian tissues t

Direct ovarian effects and safety aspects of GnRH agonists and antagonists

Autor: R.M.J. Janssens, L. Brus, C.B. Lambalk, D. J. Cahill, Joop Schoemaker, Judith A.F. Huirne

Publikováno v: Human reproduction update. 6(5)

In in-vitro fertilization programmes, gonadotrophin releasing hormone (GnRH) agonists are now routinely used in order to prevent the undesired pre-ovulatory spontaneous luteinizing hormone surge. The first publications are now appearing in which GnRH

In-vitro fertilization in a spontaneous cycle: easy, cheap and realistic

Autor: R.M.J. Janssens, Joop Schoemaker, Roel Schats, C.B. Lambalk, J.P.W. Vermeiden

Publikováno v: Human reproduction (Oxford, England). 15(2)

The results of in-vitro fertilization in natural cycles (NIVF) in women with tubal infertility at our department are presented. The study had a prospective design. We needed 75 cycles in 50 patients to obtain one oocyte from each patient. Successful

A case is reported of successful in-vitro fertilization (IVF) and pregnancy in a natural cycle after four previously failed attempts with stimulated cycles. The patient began treatment at the age of 36 years and underwent four stimulated IVF cycles,

Gonadotrophin-releasing hormone agonist dose-dependency of pituitary desensitization during controlled ovarian hyperstimulation in IVF

Autor: J. Schoemaker, R.M.J. Janssens, Roel Schats, C.B. Lambalk, J.P.W. Vermeiden

Publikováno v: Human reproduction (Oxford, England). 13(9)

The aim of this study was to find the minimal effective daily s.c. dose of the gonadotrophin-releasing hormone (GnRH) agonist, triptorelin acetate, that suppresses the GnRH-induced release of luteinizing hormone (LH) at time of human chorionic gonado
