RESUMEN

Purpose: To assess the outcome of excess follicle aspiration before intrauterine insemination (EFABI) in intrauterine insemination (IUI) cycles with 4-6 follicles ≥14 mm. Methods: A retrospective case-control study with 1559 patients undergoing IUI (donor and husband's sperm), of whom 86 underwent EFABI. We studied also an historical series of 2213 patients before EFABI implementation. For 3.5 years, all women undergoing IUI developing 4-6 follicles ≥14 mm were offered EFABI on the day of hCG administration. Pregnancy rates (PRs), multiple PRs, and adverse effects were measured. Results: EFABI was associated with a similar multiple PR (17.8% vs 17.5% in non-EFABI cases), with no triplets in EFABI patients. Live birth rates were significantly higher in EFABI cycles in IUI overall (25.5% vs 15.2%). When considered separately, the performance of EFABI resulted in significantly increased live birth rates in IUI-donor cycles (32.5% vs 18.5%), whereas the differences in IUI-husband cycles (19.5% vs 12.9%) did not reach statistical significance. The PR was 21.2% during the EFABI implementation period and 19.4% in the pre-EFABI period. Conclusions: EFABI in cycles in which 4-6 follicles reach ≥14 mm is a simple option that reduces cycle cancellation rates, results in higher PRs than cycles with 1-3 follicles, and lowers the risk of multiple pregnancy.

RESUMEN

Rennin-angiotensin system (RAS) has been involved in sperm function, even so, little is known about the implication of one of the RAS axis formed by Ang-(1-7) (angiotensin-(1-7)) and MAS receptor. Hence, in the present work, we focused on elucidating the function of the MAS receptor in human spermatozoa. We analyzed the expression and localization of MAS receptor in human spermatozoa and we observed if its activation is able to modulate the sperm motility of normal motility and/or asthenozoospermic patients, as well as, the acrosome reaction of the spermatozoa. MAS receptor is present in human mature spermatozoa, not only at the mRNA level but also at protein level. MAS is localized at the acrosome region, as well as, in the tail of spermatozoa. The sperm incubation with MAS agonist Ang-(1-7) activates at dose-dependent manner the PI3K/AKT pathway (P < 0.01 vs control) and improves the motility of asthenozoospermic patients (P < 0.01 vs control), which is blocked by the specific antagonist (A779) (P < 0.01), but it do not modulate the acrosome reaction. These findings suggest that the ACE2/Ang-(1-7)/Mas axis may be a useful biochemical tool for the treatment of male infertility related to sperm mobility.

RESUMEN

OBJECTIVE: In this study, we aimed to explore the total burden of constipation in our setting by measuring aggregate laxative consumption data and hospital admissions potentially associated with complications of chronic constipation. In addition, we aimed to determine point prevalence of individual laxative use. METHODS: This study was carried out across all public psychiatric hospitals in the Basque Country. First, laxative consumption data was obtained for the period from January 2008 to October 2016. Total laxative use was then calculated as the total number of individual daily defined doses (DDD). Second, we analyzed the number of admissions to any public acute health-care hospitals for constipation complications. Third, a cross prevalence study was performed to estimate the point constipation prevalence on December 2016. RESULTS: A mean consumption of oral laxatives around 1 DDD per stay and 1 enema per 100 stays was found. A total of 192 admissions potentially associated with constipation complications were recorded. At the time of the study, approximately half of admitted patients had at least one laxative prescribed. CONCLUSIONS: Our study highlights the important burden constipation represents in psychiatric inpatients. Although frequently neglected, it can lead to serious adverse clinical consequences.

RESUMEN

In this retrospective study, the efficiency of carrying out rescue intrauterine insemination (IUI) in low-responder patients undergoing IVF when no oocytes were retrieved after follicular aspiration and when HCG timing was adequate was analysed. A historical control group was used. Over 13 years, women undergoing IVF with failure to obtain oocytes at follicular aspiration underwent rescue IUI if the following criteria were met: adequate HCG timing; one normal tube; motile sperm count after preparation over 3 million/ml; and ultrasound visualization of one to six follicles over 13 mm. The rescue IUI was carried out 1 h after follicular aspiration. Results were compared with those of a standard IUI population (5394 cycles) in the same period. Confidence intervals were calculated using Poisson 97.5% confidence upper tail limits when no event was observed in the study sample. No pregnancies were achieved among the 54 cases who underwent rescue IUI (confidence interval: 0 to 6.8%). This pregnancy rate was lower than that observed in the general IUI population (17.5%) (relative risk, 19.2). After adjusting for age and endometriosis, the relative risk was 11.7. The rescue IUI is an inefficient procedure. Its efficacy is unlikely to exceed 7% pregnancy rate per IUI.

RESUMEN

OBJECTIVE: The purpose of this study was to compare the pregnancy rate in an artificial insemination donor program in women with minimal endometriosis and in women without endometriosis. STUDY DESIGN: A prospective double-blinded study was conducted in women with azoospermic partners. RESULTS: The per-cycle pregnancy rate was 8.6% (9/104 women) in the minimal endometriosis group vs 13.3% (26/196 women) in the control group. The per-woman pregnancy rate was 37.5% (9/24 women) in the minimal endometriosis group and 51.0% (26/51 women) in the control group. CONCLUSION: Pregnancy rates were statistically similar in normal women and in women with minimal endometriosis.

RESUMEN

OBJECTIVE: To evaluate the influence on sperm parameters and in vitro fertilization (IVF) outcomes of the administration of 400 mg/day of vitamin E for 3 months to men from infertile couples who are undergoing IVF. DESIGN: Double-blind, placebo-controlled, randomized study. SETTING: Human reproduction unit of a university hospital. PATIENTS: A total of 101 couples, 50 in the vitamin E group and 51 in the placebo group, undergoing IVF, among whom 64.4% of cases had an abnormal spermiogram according to World Health Organization (WHO) criteria. INTERVENTIONS: Vitamin E (α-tocopherol), 400 mg daily by mouth for 3 months, with sperm analysis performed immediately before starting the treatment and 3 months later on the day of IVF. MAIN OUTCOME MEASURES: WHO sperm parameters and IVF outcomes. RESULTS: Although there was a statistically significant increase in progressive motility in the vitamin E group compared with before-treatment values, a similar increase occurred in the placebo group. Normal morphology was even better in the placebo group. Regarding IVF outcomes, better fertilization rates were observed in the placebo group, but the live-birth rate per transfer was statistically significantly higher in the vitamin E group: 17 (41.46%) of 41 versus 9 (20.46%) of 44 in the placebo group. Although the clinical pregnancy rates (both per transfer and per cycle started) and the implantation rate were somewhat higher in the vitamin E group (43.9% and 25%; 36.0% and 22.0%; and 24.7% and 14.1%, respectively), the increase was not statistically significant. CONCLUSIONS: The effect of vitamin E on classic sperm parameters was not an improvement over placebo. Nonetheless, vitamin E administration was associated with a statistically significantly higher live-birth rate, and there was a trend toward better results in other IVF parameters.

RESUMEN

BACKGROUND: The aim was to ascertain whether using ultrasound guidance during intrauterine insemination (IUI) could increase pregnancy rates (PRs). METHODS: The population under study consisted of 73 consecutive couples subjected to IUI in our Human Reproduction Unit, between June and December 2006, with a total of 231 IUI cycles performed. The patients were randomized using a computer-generated random numeric table into two groups: ultrasound-guided IUI group (n = 33) and clinical IUI group (n = 40). RESULTS: The PR was 16.0% per cycle in ultrasound-guided IUI and 16.8% in the control group, no statistically significant differences being observed between the groups. The 95% confidence interval for the difference in PRs of 0.8% was -8.8 to 10. There were no differences in PR per woman, nor in first-cycle PR. The cumulative PR was also similar in both populations. Although the initial intention was to perform a study involving a larger number of cases, after a first interim analysis, the study was interrupted due to its futility. There were no differences in PR according to the different cervico-uterine angles. CONCLUSIONS: Ultrasound-guided IUI does not produce better results than blind insemination, because the PR per cycle is similar. ClinicalTrials.gov ID NCT00809952.

RESUMEN

OBJECTIVE: To determine the implication of general physical activity and some specific sports in semen quality in men from infertile couples. STUDY DESIGN: This is an observational study performed in men from infertile couples (n = 454). The interventions performed involved analyzing semen quality parameters according to 2010 WHO criteria and assessing physical activity by means of an International Physical Activity Questionnaire. RESULT(S): There was no association between different levels of general physical activity and semen parameters. We neither found association with running, cycling and racquet sports. Interestingly, people who practice weightlifting more than two hours per week presented significantly lower sperm concentration (linear coefficient = -24.80) and lower total sperm count (linear coefficient = -70.87) in comparison with participants that did not practice regular exercise. CONCLUSION(S): From a reproductive point of view, there does not seem to be any reason to recommend the increase or the decrease in general physical activity in males from infertile couples. However, additional studies are needed to investigate the relationship between weightlifting and sperm quality.

RESUMEN

In this study, we aimed to determine whether an inconsistent appearance of antipsychotic drugs dispensed was associated with poorer adherence in patients with schizophrenia.To conduct this study, we linked information from different administrative healthcare databases from the Basque Country. Patients with a medication possession ratio (<80%) were considered to be nonadherent.More than a quarter of the study population (26.9%, 1294/4810) was nonadherent to antipsychotics. Different brands of the same antipsychotic were dispensed to 8.5% of the patients. Inconsistent appearance was not associated with nonadherence to antipsychotics. Lower adherence to antipsychotics was associated with several other factors: age ≥65 or <30 years, prescription of typical antipsychotics or of long-acting injectable compounds, and nonadherence to antihypertensive and lipid-lowering drugs.Contrary to our expectations, we did not find a significant association between inconsistent appearance of prescribed antipsychotics and poorer adherence. The percentage of patients who were dispensed different brands of the same antipsychotics was also lower than expected.

RESUMEN

OBJECTIVE: To assess the utility of transforming an in vitro fertilization (IVF) cycle with low ovarian response to an intrauterine insemination (IUI) cycle. STUDY DESIGN: The inclusion criteria were women undergoing IVF because of idiopathic infertility, a mild to moderate male factor or IUI failure, with at least 1 normal, patent tube. When ovarian stimulation produced 2-4 follicles > or = 18 mm, the IVF cycle was converted to an IUI cycle. In cases with 4 follicles, estradiol had to be < 800 pg/mL. A total of 57 cycles were analyzed. RESULTS: The clinical pregnancy rate (PR) was 14.0% (8/57) in IVF cycles converted to IUI vs. 17.3% in our general IUI population (240/1,389). Converted cycles were associated with longer ovarian stimulation and with lower estradiol levels and less mature follicles than was IUI in the general population. There was a trend toward higher PR in women starting ovarian stimulation with 225 IU of gonadotropins (18.2%) than in those starting with higher doses (8.6%) (P > .05). CONCLUSION: In IVF low responders with at least 1 normal, patent tube when 2-4 follicles are observed, converting the IVF cycle to an IUI cycle yields a PR of 14.0%. This option should be considered in the management of low responders, especially those not stimulated with high doses of gonadotropins.

RESUMEN

OBJECTIVE: To compare the results of intrauterine insemination (IUI) when GnRH antagonist was added-to avoid IUI on weekend-with those obtained with the standard IUI protocol. STUDY DESIGN: In an IUI program under ovarian stimulation with gonadotropins when one or more follicles of 15-16 mm were seen, if it was not possible for logistic reasons (weekend) to perform the insemination 72 h later, GnRH antagonist was administered until human chorionic gonadotropin (hCG) administration. The IUI was performed on Monday. We compared the results of this IUI "weekend-free'' group with our results in standard IUI cycles, where IUI was performed 36-38 h after reaching optimal follicular growth. RESULTS: Both groups were comparable regarding the main demographic parameters, except for higher estradiol levels, due to the prolonging ovarian stimulation. The per cycle pregnancy rate (PR) were very similar in both groups: 15.7% in the weekend-free IUI versus 16.5% in standard IUI. The multiple pregnancy rate and the hyperstimulation rate were also similar. A non-significant trend to higher high-order multiple pregnancy was observed in the weekend-free IUI. CONCLUSIONS: In IUI cycles under ovarian suprastimulation with gonadotrophins, the use of GnRH antagonist allows the manipulation of the follicular development in such a way that it is possible to avoid inseminations on the weekends, without apparently reducing the PR.
