OBJECTIVE: To evaluate the efficacy of oral micronized progesterone compared with IM progesterone in oil for luteal support in patients undergoing IVF who are treated with a GnRH agonist. DESIGN: Randomized prospective clinical trial. SETTING: University-based IVF center. PATIENT(S): Women <40 years of age who were undergoing IVF with luteal GnRH pituitary down-regulation. INTERVENTION(S): Patients were randomized to receive either oral micronized progesterone (200 mg three times daily) or IM progesterone (50 mg daily). MAIN OUTCOME MEASURE(S): Progesterone levels at standardized days 21 and 28, and pregnancy and embryo implantation rates. RESULT(S): Day 21 progesterone levels were 77.6+/-13.2 ng/mL in the IM group and 81.5+/-16.2 ng/mL in the oral group. Day 28 progesterone levels were 76.3+/-15.0 ng/mL in the IM group and 53.6+/-10.1 ng/mL in the oral group. The clinical pregnancy rates were 57.9% and 45.8% for the IM and oral groups, respectively. The implantation rate per embryo was significantly higher in the IM group (40.9%) than in the oral group (18.1%). CONCLUSION(S): When used according to our protocols, oral progesterone and IM progesterone result in comparable levels of circulating progesterone. However, oral progesterone results in a reduced implantation rate per embryo

BACKGROUND: The Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome occurs in 1 of every 4,000-5,000 female births. It is characterized by normal external genitalia, an absent vagina, absent or rudimentary uterus, and normal fallopian tubes and ovaries. When associated with a rudimentary uterine horn, cyclic catamenial pelvic pain may result. The standard procedure for pain relief has been removal of the uterine horn by laparotomy. CASE: A rudimentary uterine horn was diagnosed in a woman with MRKH syndrome who developed monthly severe pelvic pain. Removal of the structure was performed via laparoscopy. The patient had complete resolution of her pain. CONCLUSION: As an alternative to laparotomy, laparoscopic resection of a rudimentary horn in patients with MRKH syndrome is both feasible and beneficial in the treatment of pelvic pain

OBJECTIVE: To report our experience with genetic screening of oocyte donor candidates and to determine the frequency with which significant genetic issues are identified. DESIGN: Prospective genetic screening of oocyte donor candidates. SETTING: University hospital oocyte donation program. PATIENT(S): Women presenting consecutively as volunteer oocyte donors. INTERVENTION(S): Genetic screening was performed by pedigree analysis and laboratory studies. MAIN OUTCOME MEASURE(S): Inclusion in the oocyte donor pool based on the results of clinical evaluation and laboratory tests consisting of polymerase chain reaction based mutational analysis for cystic fibrosis carrier status, cytogenetic analysis for karyotype, enzymatic assay for Tay-Sachs disease carrier status, and complete blood count and hemoglobin electrophoresis. RESULT(S): Eight (11%) of 73 oocyte donor candidates were excluded from the donor pool because of a potentially serious genetic finding. Cystic fibrosis mutations were identified in 5 candidates (7%), abnormal karyotypes were found in 2 (3.5%), and an autosomal dominant skeletal dysplasia was identified in 1 (1.4%). CONCLUSION(S): A significant proportion of women who present as candidates for oocyte donation are inappropriate for donation because of their genetic history or genetic testing results. A thorough genetic evaluation, including a history and laboratory screening, is essential to any oocyte donation program to maximize positive outcomes in pregnancies achieved through assisted means

Two women had infertility due to a symptomatic unicornuate uterus associated with rudimentary contralateral horn. Both carried successful pregnancies after laparoscopic resection of the horns

PURPOSE: To compare the use of human chorionic gonadotropin (hCG) to a gonadotropin releasing hormone (GnRH) agonist, nafarelin, in initiating ovulation and supporting the luteal phase after priming with clomiphene. METHODS: In 26 infertile women 50 mg clomiphene citrate produced a preovulatory-size follicle. Then, 11 women were randomized to receive two 400-micrograms doses of nafarelin intranasally 16 h apart, and 15 women were injected intramuscularly with 5000 IU of hCG (luteal day 0 = LD0). Starting on LD6, 7 more 400-micrograms doses of nafarelin were repeated on an every 16-h schedule or a single 2500 IU dose of hCG was given, respectively. Serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), progesterone (P), and hCG were measured. On LD13, endometrium was evaluated with ultrasonography and biopsy in 19 nonpregnant women. RESULTS: As judged by a threefold rise in serum LH, an LH surge was detected on LD1 in all 11 nafarelin patients, but in only 8 hCG patients (P = 0.01). LH and FSH levels were significantly higher on LD1, 7, and 8 and were significantly suppressed on LD13 in the nafarelin group. All patients had mid-luteal P levels greater than 10 ng/ml and luteal phases longer than 13 days. Significantly different luteal E2 or P levels were noted only on LD13, with lower values in the nafarelin group. Pregnancies were achieved in 3 of 11 nafarelin cycles and 2 of 15 hCG cycles. Luteal phase defects were also similar: 4 of 8 nafarelin patients and 7 of 11 hCG patients. CONCLUSION: Nafarelin or hCG in conjunction with clomiphene can result in viable pregnancies, but is associated with low pregnancy rates and a high incidence of luteal phase defects

OBJECTIVE: To evaluate the use of a cervical tenaculum to improve ovarian access during oocyte retrieval. DESIGN: Description of a new technique. SETTING: Normal human volunteer in an academic research environment. PATIENT: An infertile woman undergoing controlled ovarian hyperstimulation and ultrasound-guided oocyte retrieval. Access to her right ovary was obstructed by her uterus. INTERVENTIONS: During the retrieval procedure, a tenaculum was applied to the patient's cervix and downward traction was applied. RESULTS: The ovary became closer to the vaginal wall. CONCLUSION: Applying downward cervical traction with a tenaculum can bring an ovary closer to the vaginal wall, avoiding possible uterine injury and facilitating oocyte collection
