[Show abstract][Hide abstract] ABSTRACT: Our aim was to study ways to improve IVF success rates in women with suspected endometrial receptivity defects.
We conducted a retrospective cohort study examining the effect of letrozole (aromatase inhibitor) on integrin expression as a marker of endometrial receptivity. We compared IVF outcomes in 97 infertile women who had undergone ανβ3 integrin assessment by immunohistochemistry in mid-luteal endometrial biopsies. Of 79 women undergoing standard IVF, 29 (36.7%) lacked normal integrin expression. Eighteen other women with low integrin were studied after receiving letrozole during early IVF stimulation. An independent set of ανβ3 integrin-negative patients (n = 15) who had undergone repeat endometrial biopsy for integrin testing while taking letrozole were re-evaluated.
Clinical pregnancy and delivery rates were higher in women with normal ανβ3 integrin expression compared with those who were integrin negative [20/50 (40%) versus 4/29 (13.8%); P = 0.02 and 19/50 (38%) versus 2/29 (7%); P < 0.01, respectively]. In 18 women who received letrozole early in IVF, 11 conceived (61.1%; P < 0.001) compared with integrin-negative patients who did not receive letrozole. In integrin-negative women who were rebiopsied on letrozole, 66.7% reverted to normal integrin expression. Positive endometrial aromatase immunostaining using a polyclonal antibody was a common finding in infertile patients compared with controls.
Lack of endometrial ανβ3 integrin expression is associated with a poor prognosis for IVF that might be improved with letrozole co-treatment. Prospective studies are needed to confirm and extend these findings but the data suggest that aromatase expression may contribute to implantation failure in some women.

[Show abstract][Hide abstract] ABSTRACT: To improve serum metabolic and endocrine measures known to influence fecundity.
Twelve infertile, obese women were enrolled in a 12-week program of diet and exercise. Subjects underwent baseline testing for estrone (E1), estradiol (E2), testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), prolactin, fasting leptin, dehydroepiandrosterone sulfate (DHEAS), C-reactive protein (CRP) and total cholesterol. Glucose and insulin levels were measured fasting and 2 hours after a 75-g glucose load. Subjects attended three 1-hour exercise sessions per week and received instructions for a 1,200- to 1,300-kcal/day diet. Serum tests and body mass index (BMI) were remeasured after 12 weeks. Intermenstrual intervals were also recorded. At 24 weeks, subjects rated compliance with diet and exercise. Main outcome measures included change in serum variables, BMI and intermenstrual interval.
BMI, total cholesterol and E1/E2 ratio significantly decreased over 12 weeks (mean difference +/- SEM, 2.06 +/- 0.51 kg/m2, 25.91 +/- 4.33 mg/dL and 0.7 +/- 0.22, respectively). No significant differences were noted for all other measures. Ten of the 12 subjects (83%) showed menstrual improvement, with 8 becoming eumenorrheic.
Favorable metabolic and menstrual changes are possible in obese, infertile women after 12 weeks of diet and exercise.

[Show abstract][Hide abstract] ABSTRACT: Multiple pregnancies from ART procedures are all too common. Efforts to reduce high-order multiple pregnancies will require both social and medical reforms. In lieu of a legislative agenda to reduce multiple pregnancies in the United States, efforts must come from the personnel within the individual ART clinics. The approach to the problem includes accepting a lower pregnancy rate than otherwise might be obtainable, if the observed rate of high-order multiple pregnancies is above a certain threshold. Expanding the opportunities for ART reimbursement will ultimately address this problem in the United States, but until then, it is a problem that will not go away without commitment and resolve.

[Show abstract][Hide abstract] ABSTRACT: To prospectively compare pregnancy rates for couples undergoing IUI by a single healthcare provider with random assignment to either rigid (Tomcat; Kendall Sovereign, Mansfield, MA) or flexible (Soft Pass; Cook, Spencer, IN) catheters.
Randomized, controlled study.
Tertiary care infertility practice.
One hundred infertile women enrolled from a single infertility practice who met the inclusion and exclusion criteria for IUI were enrolled. Of the 100 patients, 95 underwent ovarian stimulation before IUI: 35 with clomiphene citrate alone, 60 with clomiphene citrate combined with a single dose of gonadotropins.
Timed IUI was performed with either rigid (Tomcat) or flexible (Cook) insemination catheters.
Pregnancy rate per cycle.
No differences were noted between groups for the following: age, length of infertility, day-3 FSH level, number of prior IUI cycles, total motile sperm count, days of abstinence, infertility diagnoses, insemination ratings, and stimulation protocols. No difference in pregnancy rates was observed between rigid and flexible catheter groups.
There is no statistically significant difference between flexible and rigid catheters for IUI.

[Show abstract][Hide abstract] ABSTRACT: Transvaginal, ultrasound-guided oocyte retrieval has become the gold standard for IVF therapy. Despite a low reported complication rate, here a case is reported of acute ureteral obstruction following seemingly uncomplicated oocyte retrieval. Prompt diagnosis and ureteral stenting led to rapid patient recovery with no long-term urinary tract sequelae. Ureteral injury needs to be included in the differential diagnosis of a patient presenting with pelvic/abdominal pain following oocyte retrieval.

[Show abstract][Hide abstract] ABSTRACT: Vaginal atresia is often associated with high imperforate anus. Because the commonly used methods of surgical vaginal creation (eg, McIndoe, intestinal segment interposition) may adversely affect urinary and fecal continence, the less-invasive Vecchietti procedure was selected for a young adult with a successfully corrected high imperforate anus.
A 21-year-old was born with a high imperforate anus, vaginal atresia, right hemi-uterus, and left renal agenesis. A colostomy was done at birth, a pull-through procedure at 9 months, and a stoma closure 3 months later. At age 13, an obstructed and dilated right hemiuterus and fallopian tube were resected. A laparoscopic version of the Vecchietti procedure was used for creation of a neovagina.
After the patient had been in the hospital for 2 days, traction was gradually advanced every other day in the office. At 2 weeks postoperatively, the bead was removed revealing a 7-cm vagina. Further elongation was achieved using the Frank method, while continence remained intact.
The Vecchietti procedure is an attractive, minimally invasive alternative for creation of a neovagina in patients at risk for compromise to their vesico-anorectal continence.
