Successful Pregnancies After Adequate Hormonal Replacement in Patients With Combined Pituitary Hormone Deficiencies.

CONTEXT: Women with hypopituitarism have lower pregnancy rates after ovulation induction. Associated pituitary hormone deficiencies might play a role in this poorer outcome. OBJECTIVE: We evaluated fertility treatment and pregnancy outcomes in five women with childhood-onset combined pituitary hormone deficiencies (CPHD). PATIENTS AND METHODS: Five women with CPHD were referred for fertility treatment after adequacy of hormone replacement was determined. Patients were subjected to controlled ovarian stimulation (COS) for timed intercourse, intrauterine insemination, or in vitro fertilization, according to the presence or absence of other infertility factors (male or tubal). RESULTS: All women became pregnant. The number of COS attempts until pregnancy was achieved varied between 1 and 5. The duration of COS resulting in at least one dominant follicle varied between 9 and 28 days, and total gonadotropin consumed varied between 1200 and 3450 IU. Two patients with severely suppressed basal gonadotropin levels since an early age had a cancelled COS cycle. All pregnancies were singleton except one (monochorionic twin gestation). The gestational ages at birth ranged from 35 weeks to 39 weeks and 4 days; three patients underwent cesarean section, and two had vaginal deliveries. Only one newborn was small for gestational age (delivered at 35 weeks). CONCLUSION: Adequate hormonal replacement prior to ovarian stimulation resulted in successful pregnancies in patients with childhood-onset CPHD, indicating that hormone replacement, including growth hormone, is an important step prior to fertility treatments in these patients.

Study of two strategies to induce follicular wave emergence for assisted reproductive treatments (ART)-a preliminary trial.

PURPOSE: This study aimed to induce follicular wave emergence (FWE) using pharmacological (recombinant hCG administration) or mechanical (aspiration of dominant follicle) interventions in infertile women. METHODS: Sixteen infertile women (≤35 years) with indications for in vitro fertilization due to tubal and/or male factor infertility were randomized into three groups: control (n = 6), pharmacological (n = 5) and mechanical (n = 5) groups. Women in both experimental groups underwent serial transvaginal sonograms (TVS) from menstrual cycle day 10 until identification of a dominant follicle ≥15 mm. Women in the pharmacological group received 250 µg of recombinant-hCG to induce ovulation, and resumed serial TVS 2 days later. In the mechanical group, dominant and subordinate follicles ≥10 mm were aspirated, and daily TVS was resumed on the following day. An increased pool of follicles ≥5 and ≤9 mm after interventions characterized FWE. Women in the control group underwent ovulation induction (OI) with 150 IU/day of recombinant follicle-stimulating hormone started on menstrual cycle day 3 (D3). OI was started on the day of FWE in the experimental groups. Endometrial asynchrony with development of the embryo was expected in the experimental groups. Therefore, all viable embryos were cryopreserved and transferred in an endometrial-stimulated cycle. RESULTS: The number of follicles ≥5 and ≤9 mm increased after the interventions in both experimental groups (p < .001), indicating induction of FWE. OI outcomes were similar among the groups. CONCLUSIONS: The pharmacological and mechanical interventions are efficient in inducing FWE; outcomes of OI synchronized with FWE should be further investigated.

Extensive excision of deep infiltrative endometriosis before in vitro fertilization significantly improves pregnancy rates.

STUDY OBJECTIVE: We sought to compare the outcomes of in vitro fertilization (IVF) treatments in women with infertility-associated deep infiltrative endometriosis (DIE) who underwent extensive laparoscopic excision of endometriosis before IVF with those who underwent IVF only. DESIGN: Prospective cohort study. SETTING: Infertility clinic and private hospital in São Paulo, Brazil. PATIENTS: A total of 179 infertile patients younger than 38 years had symptoms and/or signs of endometriosis and sonographic images suggestive of DIE. INTERVENTIONS: After thorough counseling, 179 women were invited to participate in a prospective cohort study with 2 treatment options: IVF without undergoing laparoscopic surgery (group A, n = 105) and extensive laparoscopic excision of DIE before IVF (group B, n = 64). Ten women were lost to follow-up. The IVF outcomes were compared between the 2 groups. MEASUREMENTS AND MAIN RESULTS: In group B, patients had 5 +/- 2 (mean +/- SD) DIE lesions excised during laparoscopy. Patient characteristics in groups A and B, respectively, were: age (32 +/- 3 vs 32 +/- 3 years, p = .94), infertility duration (29 +/- 20 vs 27 +/- 17 months, p = .45), day-3 serum follicle-stimulating hormone levels (5.6 +/- 2.5 vs 5.9 +/- 2.5 IU/L, p = .50), and previous IVF attempts (1 +/- 1 vs 2 +/- 1, p = .01). The IVF outcomes differed between groups A and B, respectively, with regard to total dose of recombinant follicle-stimulating hormone required to accomplish ovulation induction (2380 +/- 911 vs 2542 +/- 1012 IU, p = .01), number of oocytes retrieved (10 +/- 5 vs 9 +/- 5, p = .04), and pregnancy rates (24% vs 41%, p = .004), but not number of embryos transferred (3 +/- 1 vs 3 +/- 1, p = 1). The odds ratio of achieving a pregnancy were 2.45 times greater in group B than in group A. CONCLUSION: Extensive laparoscopic excision of DIE significantly improved IVF pregnancy rates of women with infertility-associated DIE.

Use of circular stapler for laparoscopic excision of rectosigmoid anterior wall endometriosis.

The objective of this study was to assess the feasibility and safety of laparoscopic rectosigmoid anterior wall discoid resection for endometriosis using the circular stapler. A retrospective analysis was conducted of nine consecutive patients undergoing laparoscopic radical excision of pelvic endometriosis, including bowel anterior wall discoid excision, at the Fertility and Pelvic Surgery Clinic and private hospitals in São Paulo, Brazil. The selected intervention was a radical laparoscopic endometriosis resection, including rectosigmoid anterior wall excision with the circular stapler. For certain types of bowel endometriosis, the anterior wall discoid stapler excision proved a suitable option that diminishes the chances of serious complications such as bowel fistula or anastomosis dehiscence.
