Progesterone level at oocyte retrieval predicts in vitro fertilization success in a short-antagonist protocol: a prospective cohort study.

Objective: To evaluate the distribution of P levels on the day of oocyte retrieval as it relates to pregnancy outcome in an antagonist protocol, which may be at higher risk for elevated P levels.

Design: Prospective cohort study.

Setting: Academic IVF center.

Is a premature rise in luteinizing hormone in the absence of increased progesterone levels detrimental to pregnancy outcome in GnRH antagonist in vitro fertilization cycles.

Objective: To determine whether a premature rise in the level of luteinizing hormone (LH) without a concomitant increase in the level of progesterone is detrimental to pregnancy outcome in flexible gonadotropin-releasing hormone (GnRH) antagonist in vitro fertilization (IVF) cycles.

Design: Retrospective cohort study.

Setting: Large academic IVF practice.

Random-start gonadotropin-releasing hormone (GnRH) antagonist-treated cycles with GnRH agonist trigger for fertility preservation.

Objective: To describe our experience with random-start IVF with the use of GnRH agonist for final oocyte maturation, to reduce the risk of ovarian hyperstimulation syndrome.

Design: Case series.

Setting: University-based center for reproductive endocrinology and infertility.

Complex X chromosome rearrangement delineated by array comparative genome hybridization in a woman with premature ovarian insufficiency.

Objective: To investigate candidate genes affected by a complex X chromosome rearrangement that may play a role in the diagnosis of spontaneous premature ovarian insufficiency (POI).

Design: Prospective cytogenetic analysis, fluorescence in situ hybridization (FISH) analysis and oligonucleotide array comparative genome hybridization (CGH).

Setting: University medical center.

The relationship between perceived stress, acupuncture, and pregnancy rates among IVF patients: a pilot study.

Unlabelled: The aim of this paper was to determine the effect of acupuncture on perceived stress levels in women on the day of embryo transfer (ET), and to determine if perceived stress levels at embryo transfer correlated with pregnancy rates. The study was an observational, prospective, cohort study based at the University IVF center.

Patient(s): 57 infertile patients undergoing IVF or IVF/ICSI.

Gonadotropin-releasing hormone agonist or human chorionic gonadotropin for final oocyte maturation in an oocyte donor program.

Objective: To compare leuprolide acetate to hCG as the trigger for final oocyte maturation in oocyte donor cycles.

Design: Retrospective review.

Setting: Academic IVF donor program.

GnRH agonist long protocol vs. a single 3-mg gnRH antagonist: a comparison of 2 protocols for pituitary down-regulation in oocyte donor-controlled ovarian hyperstimulation cycles.

Objective: To compare ovarian stimulation outcomes for 2 protocols of pituitary down-regulation in a group of fertile women.

Study Design: Retrospective outcome analysis of 35 healthy oocyte donors participating in a university-affiliated in vitro fertilization donor program from 1999 to 2004. Consecutive donor cycles were grouped according to the agent used for down-regulation (n = 27 GnRH agonist, n = 31 GnRH antagonist).
