The Desire Of Infertile Patients For Multiple Births, Ginny Ryan, S. Zhang, A. Dokras, Craig Syrop, Bradley Van Voorhis
Bradley J Van Voorhis
OBJECTIVE: To determine the proportion of infertile women who prefer a multiple birth over a singleton, patient characteristics associated with this desire, and patient knowledge about the risks of multiple births. DESIGN: Prospective analysis. SETTING: Academic university hospital-based infertility center and private general gynecology clinic. PATIENT(S): Four hundred sixty-four female patients with infertility who presented for their initial visit. MAIN OUTCOME MEASURE(S): Demographic characteristics, infertility history, desire regarding multiple births, knowledge of the risks of multiple births, and goals of infertility evaluation and treatment were determined by using a 41-question survey. Univariate analysis was performed to assess patient characteristics associated …
Detection Of Enlarged Yolk Sac On Early Ultrasound Is Associated With Adverse Pregnancy Outcomes, D. Berdahl, J. Blaine, Bradley Van Voorhis, A. Dokras
Detection Of Enlarged Yolk Sac On Early Ultrasound Is Associated With Adverse Pregnancy Outcomes, D. Berdahl, J. Blaine, Bradley Van Voorhis, A. Dokras
Bradley J Van Voorhis
Pregnancies with mean yolk sac diameter>or=5 mm on early ultrasound require monitoring and counseling about a threefold increased risk for first-trimester loss independent of maternal risk factors such as age, body mass index, polycystic ovary syndrome, smoking, and diabetes. In addition, our study shows for the first time that enlarged yolk sac diameter may be associated with an increased risk of preterm delivery.

Oral Ovulation Induction Agents Combined With Low-Dose Gonadotropin Injections And Intrauterine Insemination: Cost- And Clinical Effectiveness, Ginny Ryan, V. Moss, W. Davis, Amy Sparks, A. Dokras, Bradley Van Voorhis
Bradley J Van Voorhis
OBJECTIVE: To compare the efficacy and cost-effectiveness of different induction protocols involving gonadotropins with intrauterine insemination (IUI). STUDY DESIGN: We performed a retrospective chart review of 648 IUI cycles. Some patients had gonadotropin injections alone before human chorionic gonadotropin (hCG) and IUI (human menopausal gonadotropin protocol); others were given oral medications, then gonadotropins before hCG and IUI (combination protocol). Outcomes included pregnancy rates, multiple birth rates, endometrial thickness, number of ovarian follicles, injection days, ampules of gonadotropins and cost. RESULTS: The combination protocol was more cost-effective. In first cycles, pregnancy rates, multiple birth rates, number of large follicles produced and …

Bradley J Van Voorhis
OBJECTIVE: To determine the cost-effectiveness of infertility treatments. DESIGN: Retrospective cohort study. SETTING: Academic medical center infertility practice. PATIENT(S): All patients treated for infertility in a 1-year time span. INTERVENTION(S): Intrauterine inseminations, clomiphene citrate and IUI (CC-IUI), hMG and IUI (hMG-IUI), assisted reproductive techniques (ART), and neosalpingostomy by laparotomy. MAIN OUTCOME MEASURE(S): All medical charges and pregnancy outcomes associated with the treatments were obtained. Cost-effectiveness ratios defined as cost per delivery were determined for each procedure. The effects of a woman's age and the number of spermatozoa inseminated on cost-effectiveness of the procedures was also determined. RESULT(S): Intrauterine inseminations, CC-IUI, …

Expression And Localization Of Inducible And Endothelial Nitric Oxide Synthase In The Rat Ovary. Effects Of Gonadotropin Stimulation In Vivo, Bradley Van Voorhis, K. Moore, P. Strijbos, S. Nelson, S. Baylis, D. Grzybicki, C. Weiner
Bradley J Van Voorhis
Nitric oxide is reportedly involved in the regulation of several ovarian processes, yet the isoforms of nitric oxide synthase (NOS) expressed in the ovary are unknown. Our purpose was to identify and localize NOS isoenzymes in the rat ovary and to examine++ if mRNA expression of NOS isoenzymes change after gonadotropin stimulation. Using reverse transcriptase-PCR, we demonstrated that inducible (iNOS) and endothelial (eNOS), but not neuronal, NOS mRNAs are expressed in the ovary. In a gonadotropin-stimulated rat model, unstimulated ovaries had the highest levels of iNOS mRNA as quantified by ribonuclease protection assay. After gonadotropin injection, iNOS mRNA declined to …

Autoantibodies And Infertility: A Review Of The Literature, Bradley Van Voorhis, D. Stovall
Bradley J Van Voorhis
The role that autoantibodies play in infertility remains uncertain. There are conflicting data regarding the prevalence of autoantibodies in women with endometriosis. Certainly no one has demonstrated an association between the presence of antibodies in women with endometriosis and infertility. Despite intensive study, there is also no consensus on a role of autoantibodies to the zona pellucida as a cause of infertility. Recently, much attention has been focused on autoantibodies and infertility particularly with regards to phospholipid antibodies and their effect on IVF success rates. The literature suggests that women with infertility have an increased prevalence of phospholipid antibodies compared …

Bradley J Van Voorhis
IVF/intracytoplasmic sperm injection (ICSI) using surgically retrieved spermatozoa (SRS) is a key option in the treatment of severe male infertility. It was aimed to develop a computational model for the prediction of this modality's outcome. A dataset of 113 exemplars, derived from patients who underwent IVF/ICSI with SRS, was retrospectively analysed. The dataset, containing input features maternal age, sperm retrieval technique, type of spermatozoa used, type of male factor and output intrauterine pregnancy, was randomized into a modelling ('training') set of 83 and cross-validation ('test') set of 30. neUROn++, a set of C++ programs, was used to model the dataset …
