John Wright; Claude Duchesne; Stéphane Sabourin; F. Bissonnette; J. Benoit; Yvan Girard

The purpose of this study was to evaluate gender differences in psychosocial responses of 449 consecutive first-admission couples in a fertility clinic. Consistent with previous research, infertile women showed higher distress than their partners on a global measure of psychiatric symptoms and subscales of anxiety, depression, hostility, and cognitive disturbances, as well as on measures of stress and self-esteem. When compared with same-sexed population norms on the measure of psychiatric symptoms, both male and female infertile patients were significantly more distressed than average. No evidence was found for unusually high levels of marital or sexual distress at intake. Implications of results for clinical management are explored.

Results of laparoscopic treatments of ovarian endometriomas: laparoscopic ovarian fenestration and coagulation

Robert Hemmings; F. Bissonnette; Renda Bouzayen

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.

Increased risk of preterm birth in singleton pregnancies after blastocyst versus Day 3 embryo transfer: Canadian ART Register (CARTR) analysis

S. Dar; Clifford Librach; Joanne Gunby; F. Bissonnette; L. Cowan

STUDY QUESTION Are the fetal outcomes of singleton pregnancies that result from cleavage stage embryo transfer (ET) different from the outcomes from Day 5/6 blastocyst stage ET? SUMMARY ANSWER There was a significantly higher risk of preterm birth (<37 weeks) in singletons after extended embryo culture (Day 5/6) compared with cleavage stage (Day 3) transfer. WHAT IS KNOWN ALREADY Two recent studies, from Sweden and the USA, reported an increased risk of preterm birth in singleton pregnancies after Day 5/6 ET compared with Day 3 ET. The US study also showed increased early preterm births and the Swedish study showed increased fetal malformations in this group. STUDY DESIGN, SIZE AND DURATION A retrospective cohort study was performed. Data were collected from the Canadian ART Register database for all singleton births after fresh IVF/ICSI ET cycles (2001-2009). PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 12 712 singleton births were included. Of these, 9506 resulted from a Day 3 ET and 3206 resulted from a blastocyst (Day 5/6) ET. MAIN RESULTS AND THE ROLE OF CHANCE Preterm birth rate <37 weeks (unadjusted by potential confounding factors) was higher with Day 5/6 versus Day 3 transfers (17.2 versus 14.1%, P < 0.001). Using logistic regression analysis to adjust for confounding factors, preterm birth rate <37 weeks was the only outcome significantly increased after Day 5/6 compared with Day 3 transfer (odds ratio 1.32, 95% confidence interval 1.17-1.49). The following confounding factors were adjusted for: year of treatment (2001-2009), maternal age (continuous), parity (0 versus ≥1 birth), diagnosis category, number of oocytes retrieved [≤20 versus >20 (high responder group)], insemination method (IVF versus ICSI), number of embryos transferred (1, 2 or ≥3) and the presence of a vanishing twin (≥1 fetal heart on the initial ultrasonographic examination). LIMITATIONS, REASONS FOR CAUTION Post-natal follow-up studies will be required to determine if this difference we observed translates into adverse long-term effects on these offspring. The rate of early preterm births (<32 weeks) was higher in Day 5/6 versus Day 3, but the low number of cases in this category did not have the power to show a difference (3.0 versus 2.7%, P = 0.34). WIDER IMPLICATIONS OF THE FINDINGS We found a significantly higher risk of preterm birth (<37 weeks) in singletons after extended embryo culture (Day 5/6) compared with cleavage stage (Day 3) transfer, even when adjusting for confounding factors. Our findings are in agreement with the previous two studies; however, we did not show a difference in the very preterm deliveries (unlike the US study) or in fetal malformations (as in the Swedish study). We hypothesize that there may be a deleterious effect of prolonged in vitro embryo culture on subsequent placentation. Longer term follow-up studies will be required to determine if prolonged in vitro culture to the blastocyst stage has an adverse effect on the long-term health of offspring when compared with shorter cleavage stage culture. STUDY FUNDING/COMPETING INTEREST(S) None.

In August 2010, the provincial government of Québec, Canada introduced funding of assisted reproduction treatment through the provincial health programme. Alongside this benefit, legislation was introduced to control assisted reproduction treatment activities in the province, including restrictions on the number of embryos that could be transferred in any one cycle. The aim of the programme was to transfer a single embryo in every cycle; multiple embryos could be transferred under suboptimal conditions but required physician justification. In the first 3 months of this programme, 1353 cycles of IVF were performed in five Québec assisted reproduction centres, with an overall clinical pregnancy rate of 32% per embryo transfer and 50% of transfers used elective single-embryo transfer (eSET). The multiple-pregnancy rate was only 3.7% per clinical pregnancy. In 2009, prior to the introduction of the programme, eSET was used in only 1.6% of embryo transfers, resulting in a multiple-pregnancy rate of 25.6%. These data demonstrate that providing provincially funded assisted reproduction treatment created an environment in which the aggressive use of eSET was not only possible, but also rapidly implemented. The result was a dramatic drop in multiple-pregnancy rates, approaching those for natural pregnancies.

OBJECTIVE To examine the relationship between sperm strict morphology and sperm chromatin integrity. DESIGN Prospective study. SETTING Infertility clinic. PATIENT(S) Eighty-seven consecutive semen samples from non-azoospermic men presenting for infertility evaluation and 6 samples from fertile donors. INTERVENTION(S) Assessment of standard semen parameters and sperm chromatin structure assay (SCSA) parameters (%DFI [DNA fragmentation index] and %HDS [high DNA stainability]). Evaluation of %HDS and %DFI after treatment with dithiothreitol (a thiol-reducing agent used to decondense sperm nuclei) was also undertaken. MAIN OUTCOME MEASURE(S) Relationship between sperm strict morphology defects and SCSA parameters (%DFI and %HDS). RESULT(S) We observed significant relationships between the percentage of normal sperm forms and both %HDS (r = -0.40) and sperm motility (r = 0.32). We also found significant relationships between sperm head defects and both %HDS (r = 0.40) and sperm concentration (r = -0.39). Sperm tail, midpiece, and neck defects were not significantly related to the SCSA parameters. Treatment of spermatozoa with dithiothreitol (to induce decondensation) resulted in a substantial increase in %HDS but no measurable change in %DFI. CONCLUSION(S) The observed relationship between sperm head defects and %HDS suggests that sperm head abnormalities may, in part, be due to incomplete sperm chromatin condensation.

F. Bissonnette; Louise Lapensée; Renda Bouzayen

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 patients return to normal activities.

STUDY QUESTION What was the clinical and economic impact of universal coverage of IVF in Quebec, Canada, during the first calendar year of implementation of the public IVF programme? SUMMARY ANSWER Universal coverage of IVF increased access to IVF treatment, decreased the multiple pregnancy rate and decreased the cost per live birth, despite increased costs per cycle. WHAT IS KNOWN ALREADY Public funding of IVF assures equality of access to IVF and decreases multiple pregnancies resulting from this treatment. Public IVF programmes usually mandate a predominant SET policy, the most effective approach for reducing the incidence of multiple pregnancies. STUDY DESIGN, SIZE, DURATION This prospective comparative cohort study involved 7364 IVF cycles performed in Quebec during 2009 and 2011 and included an economic analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS IVF cycles performed in the five centres offering IVF treatment in Quebec during 2009, before implementation of the public IVF programme, were compared with cycles performed at the same centres during 2011, the first full calendar year following implementation of the programme. Data were obtained from the Canadian Assisted Reproductive Technologies Register (CARTR). Comparisons were made between the two periods in terms of utilization, pregnancy rates, multiple pregnancy rates and costs. MAIN RESULTS AND THE ROLE OF CHANCE The number of IVF cycles performed in Quebec increased by 192% after the new policy was implemented. Elective single-embryo transfer was performed in 1.6% of the cycles during Period I (2009), and increased to 31.6% during Period II (2011) (P < 0.001). Although the clinical pregnancy rate per embryo transfer was lower in 2011 than in 2009 (24.9 versus 39.9%, P < 0.001), the multiple pregnancy rate was greatly reduced (6.4 versus 29.4%, P < 0.001). The public IVF programme increased government costs per IVF treatment cycle from CAD
