How often does the embryo implant at the location to which it was transferred?

OBJECTIVE: To determine how often the embryo implants exactly at the site of transfer and what additional factors may affect the eventual site of implantation in assisted reproductive technology (ART) cycles. METHODS: This was a prospective observational study of women undergoing ART treatment in a tertiary university unit. Several factors inherent to the embryo transfer (ET), such as the location of the air bubbles and uterine contractility at 1 and at 60 min after ET were assessed with two-dimensional and three-dimensional (3D) ultrasound. In women in whom there was a resulting pregnancy, the position of the gestational sac (i.e. right, left, center or low) was subsequently assessed using 3D ultrasound, and predictors of its location were evaluated. RESULTS: Of 239 recruited women with visualization of air bubbles at ET, 71 singleton gestational sacs were subsequently observed on 3D ultrasound. Overall, 40.8% (29/71) of embryos implanted at the location where the air bubbles were visualized at 1 min after ET, and 50.7% (36/71) implanted where the air bubbles were visualized at 60 min after ET (Cohen's kappa coefficients 0.21 and 0.37, respectively; comparison of agreement values: P = 0.28). Specifically, at 1 min the correspondence between the location of the air bubble and embryo implantation was 37.5% (6/16), 57.1% (8/14), 36.8% (7/19) and 36.4% (8/22) for right, left, central and lower uterus, respectively (4 × 4 contingency table, P < 0.01); at 60 min, the correspondence was 72.2% (13/18), 50.0% (9/18), 33.3% (8/24) and 85.7% (6/7), respectively (5 × 4 contingency table, P < 0.001). In addition, higher vs lower frequency of uterine contractions at 60 min was associated with different sites of implantation (5.6% (1/18), 11.1% (2/18), 27.8% (5/18) and 55.6% (10/18) vs 34.0% (18/53), 24.5% (13/53), 13.2% (7/53) and 28.3% (15/53) for right, left, central and lower uterus, respectively, P < 0.05). In particular, a high uterine contraction frequency following ET was associated with a twofold increased chance of the pregnancy implanting in the lower part of the uterine cavity (relative risk, 1.96 (95% CI, 1.08-3.56), P < 0.05). CONCLUSIONS: The position of the air bubbles within the first 60 min of ET appears to predict the site of implantation in approximately half of cases, denoting an overall poor agreement. This implies significant embryo migration, and has important clinical implications, as it demonstrates that other factors such as uterine contractility may dictate where the embryo will eventually implant following transfer.

The impact of supportive counselling on women's psychological wellbeing after miscarriage--a randomised controlled trial.

OBJECTIVE: To assess the effectiveness of supportive counselling after miscarriage. DESIGN: Randomised controlled trial. SETTING: University hospital. SAMPLE: Two hundred and eighty women with miscarriage. METHOD: Women were randomised to receive supportive counselling from a nurse (at diagnosis and 2 weeks later) or routine care. Psychological wellbeing was measured with the General Health Questionnaire (GHQ-12) and Beck Depression Inventory (BDI). MAIN OUTCOME MEASURES: Primary outcome measured the proportion of women suffering psychological distress (GHQ-12 score ≥4) at 3 months after miscarriage. Secondary outcomes were GHQ-12 and BDI scores at 6 weeks, 3 and 6 months. RESULTS: There was no difference in the proportion of women suffering psychological distress at 3 months after miscarriage (17.1% in counselling group versus 24.4% in control group; 95% CI -0.034 to 0.177; P = 0.19). However, for the subgroup of women (n = 152) with high baseline GHQ-12 scores, the median GHQ-12 score in the counselling group was significantly lower than the control group at 6 weeks (median score 3 versus 4.5 in counselling and control groups; P = 0.04) and 3 months (median score 1 versus 2.5 in counselling and control groups; P = 0.03). Similarly, for women with high baseline BDI scores (BDI > 12), the proportion for women continuing to score high was significantly lower in the counselling group 6 weeks after miscarriage (33.3 versus 61.1% in counselling group and control group; P = 0.03). CONCLUSIONS: Although the results of current study do not justify routine counselling of all women following miscarriage, a supportive counselling programme for selected women with high levels of psychological distress is promising and merits further investigation.

Effects of laparoscopic ovarian drilling in treating infertile anovulatory polycystic ovarian syndrome patients with and without metabolic syndrome.

OBJECTIVE: To compare the effects of laparoscopic ovarian drilling in treating infertile polycystic ovarian syndrome in patients with and without metabolic syndrome. DESIGN: Retrospective review. SETTING: A university-affiliated hospital in Hong Kong. PATIENTS: A total of 89 infertile anovulatory polycystic ovarian syndrome patients, who underwent laparoscopic ovarian drilling with completed metabolic screening and seen over a 5-year period from 2002 to 2007. MAIN OUTCOME MEASURES: The clinical, hormonal, and metabolic characteristics as well as spontaneous ovulation rates, reproductive outcomes, and diabetes risks during pregnancy observed after laparoscopic ovarian drilling. RESULTS: Approximately one fifth (21%) of polycystic ovarian syndrome patients had the metabolic syndrome. There were no differences in spontaneous ovulation rates (68% vs 61%, P=0.76), cumulative pregnancy rates (68% vs 61%, P=0.77), and diabetes risks during pregnancy (64% vs 42%, P=0.13) between patients with and without metabolic syndrome. CONCLUSION: Laparoscopic ovarian drilling was equally effective in inducing ovulation in polycystic ovarian syndrome patients with metabolic syndrome. Thus, patients with metabolic syndrome should not be precluded from laparoscopic ovarian drilling, which has the additional advantage of enabling full tubo-peritoneal assessment at the same time.

Gender comparison of psychological reaction after miscarriage-a 1-year longitudinal study.

OBJECTIVE: To explore men's psychological reaction and its evolutionary course over 1 year after miscarriage, to compare this reaction with that of their female partners and to investigate the possible correlation of psychological states between partners. DESIGN: Prospective 1-year longitudinal observational study. SETTING: A university-affiliated tertiary referral hospital in Hong Kong. Sample Eighty-three miscarrying couples. METHODS: The psychological reactions of miscarrying women and their male partners were assessed immediately and at 3, 6 and 12 months after miscarriage. MAIN OUTCOME MEASURES: Psychological outcomes were assessed using the 12-item General Health Questionnaire (GHQ-12) and Beck Depression Inventory (BDI). RESULTS: A substantial proportion of men (43.4%) scored high in GHQ-12 and 16.9% scored high in BDI immediately after miscarriage. In men, both psychometric scores decreased sharply within the first 3 months and reached a plateau. When compared with women, men scored significantly lower in GHQ-12 and BDI during the 1-year course after miscarriage. A planned pregnancy was a significant risk factor (P = 0.008) associated with an initial high BDI score in men. There was a significant positive correlation between couples in both GHQ-12 and BDI scores throughout the longitudinal course. CONCLUSIONS: Although the psychological impact of miscarriage on men was less enduring when compared with that on women, a significant proportion of men demonstrated psychological distress after miscarriage. The significant positive correlation in a couple's psychological reaction indicated that psychological morbidity was not confined only to a woman's own experience, but also affected her relationship with her male partner.
