RESUMO

OBJECTIVE: To investigate the impact of functional ovarian cysts on the time required to achieve pituitary suppression, follicular development, embryo quality, and pregnancy rates during IVF treatment. DESIGN: Prospective observational study. INTERVENTION(S): Daily treatment with buserelin (sc 500 microg) was initiated on day 2 of menstruation. Ultrasound and hormonal tests were performed on days 1, 7, 11, 14, and weekly thereafter until pituitary suppression was achieved. RESULT(S): 48 patients underwent 51 cycles of IVF treatment. A functional cyst was detected in three cycles (5.8%) with baseline ultrasound scan and in 27 cycles (52.9%) on day 7 of buserelin administration. Patients who developed a cyst required a significantly longer time to achieve pituitary suppression (21 vs. 7 days), had a significantly lower FSH level at the time of initiation of gonadotropins, required more ampules of gonadotropin (45 vs. 41 ampules), developed less follicles (13 vs. 17.5), and had lower embryo quality. However, there were no differences in the implantation (23.5% vs. 17.2%) and pregnancy rates (37.2% vs. 29.2%) between two groups. CONCLUSION(S): Functional cysts prolong the period to achieving pituitary suppression, increase gonadotropin requirements, and decrease follicular recruitment and embryo quality. They have, however, no negative effect on pregnancy rates.

RESUMO

Male factor infertility patients can have anomalies in their sperm nuclei, displaying high levels of loosely packaged chromatin and damaged DNA. The primary objectives of this study were to compare the extent of DNA fragmentation in the spermatozoa of healthy light and heavy smokers versus non-smokers, and to investigate its correlation with concentrations of the smoking markers cotinine and cadmium. A secondary objective was to compare the concentrations of blood cadmium and serum cotinine with corresponding concentrations in seminal plasma. Ninety-seven healthy male volunteers were divided into three groups: non-smokers, light and heavy smokers. There was no difference between the three groups with respect to age, number of ejaculations per week, serum testosterone concentration, and parameters of semen analysis. The percentages of DNA fragmentation in spermatozoa were not statistically different in the heavy smokers (12.11%), light smokers (11.66%) and non-smokers (20.41%). Serum and seminal plasma concentrations of cotinine were significantly higher in heavy smokers compared with the other groups (P < 0.0001). Median values for blood cadmium concentration were higher in heavy smokers (4.50 microg/l) than in light smokers (0.20 microg/l) and non-smokers (0.20 microg/l) (P < 0.001). Cadmium concentration in seminal plasma was significantly higher in heavy smokers (0.20 microg/l) than in light smokers (0.10 microg/l) and non-smokers (0. 10 microg/l) (P < 0.05). In summary, our results indicate no association between smoking and DNA fragmentation in the spermatozoa of healthy men.

RESUMO

OBJECTIVE: To determine the reproductive outcome of women who undergo laparoscopic tubal anastomosis. DESIGN: Observational prospective study. SETTING: University-affiliated infertility medical center. PATIENT(S): One hundred two patients seeking reversal of tubal sterilization. INTERVENTION(S): Laparoscopic tubal anastomosis was performed with a one-suture technique. MAIN OUTCOME MEASURE(S): Pregnancy rate. RESULT(S): There were 69 isthmic-isthmic, 16 isthmic-ampullary, 12 cornual-isthmic, and 5 ampullary-ampullary anastomoses. The mean operative time was 71.35 minutes. Eight patients had bilateral tubal obstruction on postoperative hysterosalpingography. Sixty-nine patients (70%) conceived. Sixty-four (65.3%) had ongoing intrauterine pregnancies, 15 (21.7%) had spontaneous abortions, and 5 (7.2%) had ectopic pregnancies. CONCLUSION(S): This study demonstrates that laparoscopic tubal anastomosis can be done safely and successfully on an outpatient basis, reducing costs and postoperative morbidity while accelerating the patient's return to normal activities.

RESUMO

PURPOSE: Our purpose was to assess the effect of pretreatment with oral contraceptives (OCs) on the formation of functional ovarian cysts during pituitary suppression with gonadotropin-releasing hormone (GnRH) agonists, subsequent follicular development, and pregnancy rates. METHODS: A retrospective case-controlled study of 31 in vitro fertilization (IVF) patients, all of whom in a previous cycle had commenced the long protocol of GnRH-agonist (Buserelin) in the early follicular phase and were pretreated in a subsequent cycle with 2 weeks of an OC containing 30 micrograms of ethinyl estradiol and 150 micrograms of desogestrel prior to GnRH-agonist administration, was undertaken. Follow-up visits were arranged after a minimum of 11 days of GnRH-agonist administration and weekly thereafter until pituitary suppression was achieved. RESULTS: Cysts were detected in 16 (51.6%) of the 31 patients not pretreated with OCs, and in 0 (0%) of the 31 patients pretreated with OCs (odds ratio = 67.1; 95% confidence interval = 5.6-350.7). Patients pretreated with OCs achieved pituitary suppression more rapidly (median difference = 4 days; 95% confidence interval = 2-7) and had comparable gonadotropin requirements and pregnancy rates. CONCLUSIONS: Pretreatment with OCs prior to pituitary suppression in the early follicular phase decreases ovarian cyst formation, without an apparent effect on subsequent follicular recruitment or pregnancy rates.


PIP: A retrospective case-controlled study was undertaken to assess the effects of pretreatment with oral contraceptive (OC) on the formation of functional ovarian cysts during pituitary suppression with gonadotropin-releasing hormone (GnRH) agonists, subsequently follicular development, and pregnancy rates. In the period between January 1997 and December 1997, 31 in vitro fertilizations, all of which in a previous cycle, had commenced the long protocol of GnRH agonists in the early follicular phase and were pretreated in a subsequent cycle with an OC containing 30 mcg ethinyl estradiol and 150 mcg desogestrel for 2 weeks prior GnRH agonist administration and then weekly until pituitary suppression was achieved. After data collection and analysis, findings revealed that functional ovarian cysts were detected in 16 (51.6%) of 31 patients not pretreated with an OC and in 0 (0%) of 31 patients pretreated with an OC. Satisfactory pituitary suppression was achieved more rapidly with patients pretreated with an OC. Further, comparable gonadotroph requirements and pregnancy rates were detected among patients pretreated with an OC. In conclusion, pretreating patients with an OC prior to pituitary suppression in the early follicular phase decreases ovarian cyst formation, without an apparent effect on subsequent follicular recruitment or pregnancy rates.

RESUMO

OBJECTIVE: To assess the effect of pretreatment with an oral contraceptive (OC) on ovarian cyst formation during pituitary suppression with buserelin acetate. DESIGN: Prospective randomized trial. SETTING: Academic medical center. PATIENT(S): Eighty-three patients who were undergoing IVF-ET treatment. INTERVENTION(S): Patients in the study group were pretreated with an OC for 14 days starting on the first day of menstruation. The administration of SC buserelin acetate was initiated on the last day of OC administration. Patients in the control group began to receive buserelin acetate on day 2 of menstruation. Hormonal assays and ultrasound scans were performed on the first day of menstruation, and 7, 11, and 14 days after the commencement of buserelin acetate administration. Thereafter, these tests were performed weekly until pituitary suppression was achieved. MAIN OUTCOME MEASURE(S): Incidence of cyst formation. RESULT(S): A cyst developed in 27 patients in the control group (52.9%) and no patients in the study group (odds ratio [OR]=115; 95% confidence interval [CI]=10-617). Patients in the study group achieved pituitary suppression faster (median difference [MD]=7 days; 95% CI=4-14) and required fewer ampules of gonadotropin (MD=10; 95% CI=6-14). They recruited more follicles (MD=3; 95% CI=0-5) and had higher pregnancy rates (37.2% versus 33.3%). CONCLUSION(S): Pretreatment with an OC abolishes ovarian cyst formation, shortens the time required to achieve pituitary suppression, and decreases gonadotropin requirements without having a negative effect on pregnancy rates.


PIP: Administration of a gonadotropin-releasing hormone analog (GnRH-a) before ovarian stimulation with gonadotropins in women undergoing in vitro fertilization (IVF) treatment produces higher pregnancy and live birth rates, but also results in formation of ovarian cysts that must be treated before stimulation can commence. The effect of pretreatment with an oral contraceptive (OC) on ovarian cyst formation during pituitary suppression with the GnRH-a buserelin acetate was investigated in a prospective randomized trial of women undergoing IVF at Royal Victoria Hospital (Montreal, Quebec, Canada). 51 women were pretreated with an OC for 14 days, starting on the first day of menstruation, and began buserelin acetate (500 mcg/day) on the last day of OC administration. The 51 women in the control group were treated with the standard protocol of 500 mcg/day of buserelin acetate starting on the second day of menstruation. A cyst developed in 27 controls (52.9%) but in no women pretreated with OCs (odds ratio, 115; 95% confidence interval, 10.7-617.5). 49 pretreated women (96.1%) compared with 22 controls (43.1%) achieved pituitary suppression after 7 days of GnRH-a administration. Pretreated women also required a median of 10 fewer ampules of gonadotropin than controls, recruited a median of 3 more follicles than their non-pretreated counterparts, and had higher pregnancy rates (37.2% and 33.3%, respectively). OCs are assumed to prevent the formation of ovarian cysts during GnRH-a administration through a dual effect of pituitary suppression and ovarian protection. OC pretreatment enables a significant simplification of the long standard protocol of GnRH-a administration.

RESUMO

OBJECTIVE: To determine the long-term results of laparoscopic fenestration and coagulation of ovarian endometriomas and to compare them with the results of ovarian cystectomy performed by either laparotomy or laparoscopy. DESIGN: Case-control study. SETTING: Two university-affiliated hospitals. PATIENT(S): One hundred fifty-six premenopausal women with ovarian endometriomas of at least 3 cm in diameter (stage 3 and 4 endometriosis, revised American Fertility Society classification). INTERVENTION(S): Laparoscopic ovarian fenestration and coagulation (group 1, 80 patients); laparoscopic ovarian cystectomy (group 2, 23 patients); and ovarian cystectomy by laparotomy and microsurgical technique (group 3, 53 patients). MAIN OUTCOME MEASURE(S): Operative findings, recurrence rate, and cumulative clinical pregnancy rate (PR) over a 36-month follow-up period. RESULT(S): The mean (+/-SD) time to first pregnancy was significantly shorter in group 1 (1.4+/-0.2 years) than in group 2 (2.2+/-0.5 years) or group 3 (2.4+/-0.5 years). The difference between the cumulative clinical PR between the three groups was not statistically significant after 36 months of follow-up. The difference in the recurrence rate among groups 1, 2, and 3 was not statistically significant. CONCLUSION(S): Laparoscopic ovarian fenestration and coagulation of endometriomas leads to faster conception than ovarian cystectomy by laparotomy. Laparoscopic ovarian fenestration and coagulation of endometriomas is associated with cumulative clinical PRs and recurrence rates over 36 months that are similar to those associated with ovarian cystectomy.

RESUMO

OBJECTIVES: To compare the metabolic and endocrinological effects of estradiol valerate/cyproterone acetate (EV/CPA) to a regimen of conjugated estrogens/medroxyprogesterone acetate (CE/MPA) in postmenopausal women. METHODS: Lipid profile, endocrinological parameters, coagulation factors, renin and angiotensinogen were followed in postmenopausal women randomized to EV/CPA or CE/MPA during 12 cycles. RESULTS: Following 12 cycles of treatment, total plasma cholesterol decreased more with EV/CPA than with CE/MPA. Low-density cholesterol decreased with EV/CPA while it increased with CE/MPA. High-density cholesterol remained fairly unchanged, and triglycerides increased significantly in both groups. Estradiol and estrone levels increased significantly more with EV/CPA than with CE/MPA while the sex-hormone-binding globulin increased more with CE/MPA. Follicle stimulating and luteinizing hormone levels also decreased significantly. Total testosterone and dihydroepiandrosterone sulfate remained stable. Total levothyroxine serum levels increased significantly, but thyroid stimulating hormone and triiodothyronine levels remained stable. Coagulation parameters also remained stable. Angiotensinogen increased, while plasma renin activity and blood pressure remained unchanged. CONCLUSION: It is concluded that both EV/CPA and CE/MPA produce favourable metabolic effects. A better lipid profile, compatible with decreased cardiovascular risk, is observed with the EV/CPA regimen. Higher circulating estrogen levels may explain in part this observation.

RESUMO

OBJECTIVES: To assess the effects of Femoston (2 mg micronised 17 beta oestradiol daily, sequentially combined in one tablet with 10 mg dydrogesterone for 14 days per 28 day cycle) on the serum lipid profile of postmenopausal women. METHODS: 188 healthy postmenopausal women with intact uteri (aged 40 to 65 years) were enrolled in an open, multicentre, one-year study. Serum lipids and lipoproteins were measured at baseline and after 3, 6 and 12 months. RESULTS: A total of 155 women completed the one-year study. Mean serum levels of total cholesterol and low-density lipoprotein (LDL)-cholesterol were significantly reduced (P < 0.01) at all assessments compared with baseline; the reductions observed at the final assessment were 5 and 20%, respectively. A significant increase of 20% (P < 0.01) was seen in high-density lipoprotein (HDL)-cholesterol levels by month 12. Mean levels of triglycerides were also increased (p < 0.01). Blood pressure and heart rate remained unchanged throughout the study. CONCLUSIONS: The results show that the overall effects of Femoston on the serum lipid profile are comparable to those found with oestrogen therapy alone and should reduce the risk of cardiovascular disease in postmenopausal women.

RESUMO

The prevalence of hypothyroidism has been reported to increase with age and to attain up to 10% in older women. We wanted to verify whether routine screening for thyroid disease could be justified in a specific sub-population of aging women, those consulting for the first time at a menopausal clinic. Standard thyroid profiles (Total T4, T3 uptake, calculated free thyroxine index (FTI), and sensitive thyroid stimulating hormone (TSH)) were obtained in 500 consecutive patients seen at such a clinic over 18 months. Thyroid microsomal and thyroglobulin antibody titers were also obtained in over half of them. Twenty-three carefully selected, age-matched, peri-menopausal hospital employees served as a reference group for the TRH response test. Thirteen women (2.6%) had previously diagnosed hypothyroidism but 4 of them were found to be sub-optimally treated. Fifty other subjects (10%) had out-of-range screening TSH levels, 7 below and 43 over the assay reference range. In the former, 3 (0.6%) were found to be hyperthyroid while in the latter 8 (1.6%) were found to be overtly hypothyroid based on TSH levels over 10 mU/L and accompanying signs and symptoms. Twelve other subjects (2.4%) were found to have sub-clinical hypothyroidism based on a positive TRH response test and a significantly increased prevalence of goiter and positive antibody titers. The remaining 23 patients had a normal TRH response test, although their mean TSH level at 30-min post-TRH and the prevalence of positive antibody titers were significantly higher than those of the control group and normal subjects respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

Substance P is a neuropeptide that has been identified in the ovary, fallopian tube, uterus, and vagina and in the hypothalamic-pituitary axis in both an animal model and human ovaries. We sought to determine if substance P is present in peritoneal fluid and, if so, whether it correlated with the cause of infertility. Its presence was determined by radioimmunoassay in the peritoneal fluid of 66 patients undergoing diagnostic laparoscopy for clinical indications related to infertility. Total volume of peritoneal fluid and cycle day were recorded; patients were evaluated in groups according to diagnosis: endometriosis (n = 24), pelvic adhesions (n = 18), and normal controls (n = 24). The level of substance P (mean +/- SEM) was 122 +/- 19 pg/ml for endometriosis and 130 +/- 19 pg/ml for pelvic adhesions. These values were not significantly different from the normal controls (130 +/- 25 pg/ml). There was no significant difference in levels between follicular and luteal phase of the menstrual cycle. We conclude that substance P is present normally in peritoneal fluid and that its levels are not affected by pelvic endometriosis or adhesions.
