Women with polycystic ovary syndrome (PCOS) undergoing ovulation induction appear to be extremely sensitive to gonadotropin stimulation and at increased risk for ovarian hyperstimulation syndrome. To determine granulosa cell responsiveness to recombinant human FSH (r-hFSH), dose-response studies were conducted in 16 individual PCOS patients and 7 normal(More)
STUDY QUESTION Is severe early ovarian hyperstimulation syndrome (OHSS) completely prevented with the GnRH agonist trigger and 1500 IU hCG luteal rescue protocol? SUMMARY ANSWER Severe early OHSS can occur even after the GnRH agonist trigger and 1500 IU hCG luteal rescue protocol. WHAT IS KNOWN ALREADY Prior studies including over 200 women who received(More)
OBJECTIVE To compare pregnancy rates (PR) for letrozole and gonadotropins in individuals who failed to conceive with clomiphene citrate (CC). DESIGN Retrospective cohort study. SETTING University reproductive center. PATIENT(S) Individuals treated with letrozole or gonadotropins who failed to conceive with CC. INTERVENTION(S) Controlled ovarian(More)
In PCOS women with insulin resistance, hyperinsulinemia may contribute to inappropriate gonadotropin secretion. To determine whether insulin influences gonadotropin release in PCOS, pulsatile LH secretion and gonadotropin responses to GnRH were evaluated before (phase 1) and during (phase 2) insulin infusion. In phase 1, 11 PCOS and 9 normal women on(More)
To assess the obstetric outcome of IVF triplets which are spontaneously or electively reduced to twins. Retrospective study of trichorionic triplets (TT) and dichorionic twins (DT) conceived with IVF. Compared to TT without reduction, TT with spontaneous reduction (SR) (OR: 5.6, 95% CI: 1.6–19.9) or elective reduction (ER) (OR: 14.0, 95% CI: 3.92–50.02) to(More)
OBJECTIVE To evaluate the pregnancy rate, ovarian responsiveness, and endometrial thickness in infertility patients with a history of methotrexate exposure who subsequently underwent controlled ovarian stimulation. DESIGN Retrospective cohort study. SETTING University reproductive endocrinology and infertility program. SUBJECT(S) Forty-eight women(More)
BACKGROUND Spontaneous heterotopic pregnancies are rare, but with assisted reproductive techniques the incidence may approach 1:100. With the widespread use of transvaginal ultrasonography, physicians have attempted treatment of heterotopic pregnancies with minimally invasive procedures such as transvaginal guided potassium chloride (KCl) injection.(More)
To examine the fertilization and developmental potential of sibling mature oocytes collected from different follicle sizes on day of retrieval in in vitro maturation (IVM) cycles. Two hundred thirty eight hCG-primed IVM cycles were performed in 213 patients with polycystic ovaries. If sibling mature oocytes were retrieved on day of collection, they were(More)
We present a rare case of a congenital isolated missing segment of the fallopian tube, including hysterosalpingographic and laparoscopic images. We conclude that when this occurs without concomitant müllerian anomalies, the mechanism of development would not be expected to be associated with an increase in renal abnormalities.
OBJECTIVES To compare rates of pregnancy and IVF parameters in subjects who were stimulated with FSH plus recombinant human luteinizing hormone or menopausal gonadotropins. To determine whether responses to type of LH differ in poor or good responders. STUDY DESIGN Retrospective analysis at a university-based fertility center. Subjects were women with(More)
