A prospective proof-of-concept trial on the effect of personalized dosages of follitropin delta in intrauterine insemination. Reprod Biomed Online 2024; 48:103603. [PMID: 38359732 DOI: 10.1016/j.rbmo.2023.103603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 09/15/2023] [Accepted: 10/04/2023] [Indexed: 02/17/2024]
Abstract
RESEARCH QUESTION What is the efficacy and safety of individualized follitropin delta dosing for ovarian stimulation in intrauterine insemination (IUI)? DESIGN This single-centre, prospective, open-label, single-cohort study involving 106 patients established an original dosing regimen based on body weight and anti-Müllerian hormone (AMH) concentrations, with adjustments based on the ovarian response from the previous IUI cycle. Each participant was enrolled in a maximum of three IUI cycles. RESULTS Mean age was 34.5 ± 4.5 years, mean weight 69.2 ± 11.2 kg, mean AMH 15.7 ± 8.6 pmol/l, mean FSH 6.3 ± 2.6 IU/l and mean antral follicle count 16.4 ± 8.2. The percentage of patients who produced more than three mature follicles was 1.9%, 0% and 1.5%, respectively, for the three IUI cycles. The percentage of patients with two or three mature follicles was 34.0%, 36.9% and 47.1% for the three IUI cycles. The clinical pregnancy rate per IUI cycle was 17.9%, 14.3% and 17.6% for the three cycles, with a cumulative clinical pregnancy rate of 40.6%. Out of 258 cycles, 43 (16.7%) resulted in clinical pregnancy, with six of those resulting in multiple pregnancies (14.0%). Two resulted in spontaneous reduction within the first trimester and four resulted in live twin births, representing only 1.6% of the total cycles. CONCLUSIONS This study is the first to utilize follitropin delta for stimulation in IUI. It demonstrates that individualized dosing is both effective and safe, resulting in satisfactory cumulative pregnancy rates and an acceptable multiple pregnancy rate, thus achieving the primary objectives of the research.

The impact of different sperm preparation methods on clinical pregnancy and live birth rates in intrauterine insemination cycles: a retrospective single-center cohort study. Fertil Steril 2023; 120:617-625.

Abstract
OBJECTIVE To assess the impact of 2 different sperm preparation methods, density gradient centrifugation and simple wash, on clinical pregnancy and live birth rates in intrauterine insemination (IUI) cycles with and without ovulation induction. DESIGN Retrospective single-center cohort study. SETTING Academic fertility center. PATIENTS In total, 1,503 women of all diagnoses sought IUI with fresh-ejaculated sperm. EXPOSURE Cycles were divided into 2 groups on the basis of sperm preparation technique: density gradient centrifugation (n = 1,687, unexposed group) and simple wash (n = 1,691, exposed group). MAIN OUTCOME MEASURES Primary outcome measures consisted of clinical pregnancy and live birth rates. Furthermore, adjusted odds ratios and 95% confidence intervals for each outcome were calculated and compared between the 2 sperm preparation groups. RESULTS Odds ratios did not differ between density gradient centrifugation and simple wash groups for clinical pregnancy and live birth (1.10 [0.67-1.83] and 1.08 [0.85-1.37], respectively). Additionally, when cycles were stratified using ovulation induction rather than adjusted for, no differences in clinical pregnancy and live birth odds were noted between sperm preparation groups (gonadotropins: 0.93 [0.49-1.77] and 1.03 [0.75-1.41]; oral agents: 1.78 [0.68-4.61] and 1.05 [0.72-1.53]; unassisted: 0.08 [0.001-6.84] and 2.52 [0.63-10.00], respectively). Furthermore, no difference was seen in clinical pregnancy or live birth when cycles were stratified using sperm score or when the analysis was limited to first cycles only. CONCLUSION Overall, no difference was noted in clinical pregnancy or live birth rates between patients who received simple wash vs. density gradient-prepared sperm, suggesting similar clinical efficacy between the 2 techniques for IUI. Because the simple wash technique is more time-efficient and cost-effective compared with the density gradient, adoption of this technique could lead to comparable clinical pregnancy and live birth rates for IUI cycles, although optimizing teamwork flow and coordination of care.

Abstract
PURPOSE The objective of this review is to define live birth rate (LBR) and clinical pregnancy rate (CPR) for women ≥ 40 undergoing ovulation induction (OI)/intrauterine insemination (IUI). METHODS A systematic review was performed in accordance with PRISMA guidelines using PubMed and Google Scholar. The primary and secondary outcomes of interest were LBR and CPR, respectively. RESULTS There were 636 studies screened of which 42 were included. In 8 studies which provided LBR for partner sperm, LBR/cycle ranged from 0 to 8.5% with majority being ≤ 4%. Cumulative LBR was 3.6 to 7.1% over 6 cycles with the majority of pregnancies in the first 4. In the four studies providing LBR for donor sperm cycles, LBR/cycle ranged from 3 to 7% with cumulative LBR of 12 to 24% over 6 cycles. The majority of pregnancies occurred in the first 6 cycles. There were three studies with LBR or CPR/cycle ≥ 1% for women ≥ 43. No studies provided data above this range for women ≥ 45. In 4 studies which compared OI/IUI and IVF, the LBR from IVF was 9.2 to 22% per cycle. In 7 studies which compared outcomes by stimulation protocol, no significant differences were seen. CONCLUSION For women ≥ 40 using homologous sperm, the highest probability of live birth is via IVF. However, if IVF is not an option, OI/IUI may be considered for up to 4 cycles in those using partner sperm or 6 cycles with donor sperm. For women > 45, OI/IUI is likely futile but a limited trial may be considered for psychological benefit while encouraging consideration of donor oocyte IVF or adoption. Use of gonadotropins does not appear to be more effective than oral agents in this age group.

Abstract
Context: In the last 10 years, assisted reproductive technologies (ARTs) have offered infertile couples an opportunity to complete their reproductive project. However, the high failure rate could be explained with the complex human reproduction system. In ART, the decrease of the success is due to the conditions far from the natural ones. Aims: The aim of this study is to evaluate deoxyribonucleic acid (DNA) damage of spermatozoa before and after selection procedures, using a new technique able to quantize sperm DNA damage. Settings and Design: They were involved 43 males domiciled permanently in two areas with different Environmental Impact, HEI (high environmental impact) and LEI (Low environmental impact), they are aged between 24 and 31 years with various degrees of dyspermia. Subjects and Methods: The 43 males were divided into two groups: 21 in Group A (EIL) and 22 in Group B (EIH). The samples must be aliquoted into parts of 0.5 mL: Group (a) Control, no processing; Group (b) Swim-up (SUP) from semen; Group (c) classic SUP; Group (d) density gradient centrifugation (DGC). All samples were subjected to a quantitative dosage of p53 protein, before and after processing. Statistical Analysis Used: For the development of the probability and significance of the data, the Student's t-test was used. Results: From our data, it emerges that Groups D and B provide a superior quality about motility, vitality, and apoptosis indexes compared to other conventional techniques. In Group B, apoptosis is comparable to Group D, but they have slightly lower about motility and vitality. Group C is the one that has lower parameters than the other techniques. Regarding the evaluation of p53 protein, the results are conflicting with the evaluation of apoptosis; in fact, in Group D, the values are significantly higher than the other techniques. Conclusions: Sperm separation is an important moment in ART techniques. From our data, it emerges a greater fragility of DNA in the male spermatozoa who reside permanently in areas with high environmental impact.

Abstract
BACKGROUND Semen preparation techniques for assisted reproduction, including intrauterine insemination (IUI), were developed to select the motile morphologically normal spermatozoa. The yield of many motile, morphologically normal spermatozoa might influence treatment choices and therefore outcomes. OBJECTIVES To compare the effectiveness of three different semen preparation techniques (gradient; swim-up; wash and centrifugation) on clinical outcomes (live birth rate; clinical pregnancy rate) in subfertile couples undergoing IUI. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility Group (CGFG) trials register, CENTRAL, MEDLINE, Embase, Science Direct Database, National Research Register, Biological Abstracts and clinical trial registries in March 2019, and checked references and contacted study authors to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing the efficacy in terms of clinical outcomes of semen preparation techniques used for subfertile couples undergoing IUI. DATA COLLECTION AND ANALYSIS We used standard methodological procedures recommended by Cochrane. The primary review outcomes are live birth rate and clinical pregnancy rate per couple. MAIN RESULTS We included seven RCTS in the review; we included six of these, totalling 485 couples, in the meta-analysis. No trials reported the primary outcome of live birth. The evidence was of very low-quality. The main limitations were (unclear) risk of bias, signs of imprecision and inconsistency in results among studies and the small number of studies/participants included.Swim-up versus gradient technique Considering the quality of evidence, we are uncertain whether there was a difference between clinical pregnancy rates (CPR) for swim-up versus a gradient technique (odds ratio (OR) 0.83, 95% CI 0.51 to 1.35; I² = 71%; 4 RCTs, 370 participants; very low-quality evidence). The results suggest that if the chance of pregnancy after the use of a gradient technique is assumed to be 24%, the chance of pregnancy after using the swim-up technique is between 14% and 30%. We are uncertain whether there was a real difference between ongoing pregnancy rates per couple (OR 0.39, 95% CI 0.19 to 0.82; heterogeneity not applicable; 1 RCT, 223 participants; very low-quality evidence). Considering the quality of evidence, we are uncertain whether there was a difference between multiple pregnancy rates (MPR) per couple comparing a swim-up versus gradient technique (MPR per couple 0% versus 0%; 1 RCT, 25 participants; very low-quality of evidence). Considering the quality of evidence, we are also uncertain whether there was a difference between miscarriage rates (MR) per couple comparing a swim-up versus gradient technique (OR 0.85, 95% CI 0.28 to 2.59; I² = 44%; 3 RCTs, 330 participants; very low-quality evidence). No studies reported on ectopic pregnancy rate, fetal abnormalities or infection rate.Swim-up versus wash techniqueConsidering the quality of evidence, we are uncertain whether there is a difference in clinical pregnancy rates after a swim-up technique versus wash and centrifugation (OR 0.41, 95% CI 0.15 to 1.13; I² = 55%; 2 RCTs, 78 participants; very low-quality evidence). The results suggest that if the chance of pregnancy after the use of a wash technique is assumed to be 38%, the chance of pregnancy after using the swim-up technique is between 9% and 41%. Considering the quality of evidence, we are uncertain whether there was a difference between multiple pregnancy rates between swim-up technique versus wash technique (OR 0.49, 95% CI 0.02 to 13.28; heterogeneity not applicable; 1 RCT, 26 participants; very low-quality evidence). Miscarriage rate was only reported by one study: no miscarriages were reported in either treatment arm. No studies reported on ongoing pregnancy rate, ectopic pregnancy rate, fetal abnormalities or infection rate.Gradient versus wash techniqueConsidering the quality of evidence, we are uncertain whether there is a difference in clinical pregnancy rates after a gradient versus wash and centrifugation technique (OR 1.78, 95% CI 0.58 to 5.46; I² = 52%; 2 RCTs, 94 participants; very low-quality evidence). The results suggest that if the chance of pregnancy after the use of a wash technique is assumed to be 13%, the chance of pregnancy after using the gradient technique is between 8% and 46%. Considering the quality of evidence, we are uncertain whether there was a difference between multiple pregnancy rates per couple between the treatment groups (OR 0.33, 95% CI 0.01 to 8.83; very low-quality evidence). Considering the quality of evidence, we are also uncertain whether there was a difference between miscarriage rates per couple between the treatment groups (OR 6.11, 95% CI 0.27 to 138.45; very low-quality evidence). No studies reported on ongoing pregnancy rate, ectopic pregnancy rate, fetal abnormalities or infection rate. AUTHORS' CONCLUSIONS There is insufficient evidence to recommend any specific semen preparation technique: swim-up versus gradient versus wash and centrifugation technique. No studies reported on live birth rates. Considering the quality of evidence (very low), we are uncertain whether there is a difference in clinical pregnancy rates, ongoing pregnancy rates, multiple pregnancy rates or miscarriage rates per couple) between the three sperm preparation techniques. Further randomised trials are warranted that report live birth data.

Abstract
OBJECTIVES The objective of our study is to evaluate the impact of luteal phase support by hCG in intrauterine inseminations preceded by ovarian gonadotropin stimulation. METHODS A retrospective study was conducted at the CHU of Nice between March 1, 2016 and October 31, 2017. During this period, 300 intrauterine inseminations were included in data analysis. Ovarian stimulation was performed by gonadotropins and a GnRH antagonist was added, if needed. Following a modification of standard operative procedure in the department, patients who performed an intrauterine insemination from December 1, 2016 received luteal phase support with two injections of hCG 1500 IU, performed at three days of interval. Pregnancy and ovarian hyperstimulation syndrome were the primary and secondary study endpoints, respectively. RESULTS Out of 300 inseminations included in the analysis, 144 were performed with luteal phase support and 156 without support. No statistically significant difference in pregnancy rate was observed between these two groups (19.4% of pregnancy in the luteal phase support group and 15.38% in the group without luteal phase support, P=0.353). No ovarian hyperstimulation syndrome occurred over the course of the study. CONCLUSION Our study shows a slight improvement of pregnancy rate in the group subjected to luteal phase support by hCG after intrauterine insemination, but the benefit was not significant. A randomised prospective study based on a large cohort could help to assess the effect of luteal phase support during intrauterine inseminations.

Abstract
The aim of this study was to investigate the possibility of using sperm function tests (hypoosmotic swelling test [HOS], aniline blue [AB] staining test, and sperm chromatin dispersion [SCD]) to predict intrauterine insemination [IUI] success rate. A total of 243 couples with mild male factor or unexplained male infertility who underwent IUI were evaluated prospectively. The results of basic sperm analysis and sperm function tests were compared between pregnant or nonpregnant groups. The HOS (11.9 ± 9.6% vs. 10.1 ± 8.5%, p = 0.35) and SCD tests (32.9 ± 21.0% vs. 29.9 ± 19.0%, p = 0.48) were not significantly different between pregnant (n = 22) and nonpregnant (n = 221) groups. However, the AB staining negativity rate was significantly higher in the pregnant group compared to the nonpregnant group (35.2 ± 20.8% and 24.4 ± 18.0%, p = 0.008). On ROC analysis, a cut-off value of 24% for AB negativity showed a sensitivity and a specificity value of 82.35% and 51.38% (AUC) = 0.653; 95% confidence interval: 0.571-0.72 P (Area = 0.5) = 0.0267, respectively, for prediction of pregnancy. Our study showed that the sperm chromatin maturity, assessed by AB stain, may predict the pregnancy in couples with unexplained female infertility plus mild male factor or unexplained male infertility. The HOS and SCD failed to predict the pregnancy in this group of couples.

Abstract
To validate semen preparation via density gradient centrifugation, we took into account the input via the semen sample, the action generated by technical and equipment characteristics and the output measured by the level of performance. Longer periods of abstinence reduced % yield, but increased viscosity and incomplete samples collected had no effect. Under controlled technical and equipment characteristics, precision and reproducibility were validated for density gradient. Additionally, as a good laboratory practice, internal and external quality control measures were implemented to guarantee the level of performance. Inseminating motile sperm count is an important predictive parameter for IUI success. In our group of patients, a yield of an absolute lower limit of 2 million motile spermatozoa was sufficient to contemplate IUI. Pregnancy rate of 13.8% where >2 million rapid progressive spermatozoa were inseminated was significantly higher than the pregnancies (4.4%) obtained with <2 million rapid progressive spermatozoa. This percentage was even higher than the national data registered for IUI (12.2%). To make IUI an attractive first-line treatment, standardization and proper validation of semen preparation procedure are mandatory.

Abstract
Context The detrimental effects of hyperinsulinemia on human ovaries during follicular development process have been shown in various studies, particularly in women with polycystic ovary syndrome. To our knowledge there is no study regarding the effect of insulin resistance (IR) on the intrauterine insemination (IUI) success in women with unexplained infertility (UEI). Objective To evaluate the effects of IR on the occurrence of pregnancy among infertile women undergoing ovulation induction (OI) with IUI for UEI. Design Prospective cohort study. Subjects and Methods 173 patients who met the criteria for UEI and under the age of 35 were included in this study. All women underwent OI with IUI and, subsequently, they were divided into two groups based on the presence of pregnancy. Data reviewed for analysis were demographic, clinical, and laboratory features. Results There were 37 (21.4%) cycles with pregnancy and 136 (78.6%) cycles without pregnancy. Median infertility duration was significantly lower in the pregnant group when compared with non-pregnants (p=0.018). The mean number of previous cycles per patient was also lower in this group (p=0.028). No significant differences were found between the groups in terms of other variables. Levels of insulin, fasting glucose and HOMA-IR were also similar between the two groups. Conclusions IR calculated by using HOMA-IR index has no positive or negative effect on the occurrence of pregnancy in women undergoing OI therapy with IUI for UEI.

The gradient technique improves success rates in intrauterine insemination cycles of unexplained subfertile couples when compared to swim up technique; a prospective randomized study. J Assist Reprod Genet 2014; 31:1139-45.

Abstract
PURPOSE To compare the efficacy of gradient and swim-up semen preparation techniques on pregnancy rates in couples undergoing intrauterine insemination (IUI) cycles with low dose gonadotropin stimulation with the diagnosis of unexplained or mild male subfertility. METHODS Two hundred and twenty three couples were randomized into swim up or gradient technique groups for sperm preperation. The clinical and on going pregnancy rates per cycle and per patient were evaluated. RESULTS Both clinical and ongoing pregnancy rates per cycle were significantly higher in the "gradient" group (19% and 16.9%) in comparision with the "swim up" group (9.7% and 6.9%) (p < 0.05). Clinical pregnancy and on-going pregnancy rates per patient were higher in the "gradient" group (26.1% and 23.4%) when compared to the "swim up" group (15.2% and 10.7%), (p < 0.05). In the subgroup of 191 unexplained subfertile couples with 290 cycles; the "gradient" group also revealed significantly higher clinical and ongoing pregnancy rates per cycle (21.6% and 17.9%) when compared with the "swim up" group (10.3% and 7.1%) (p < 0.05). In total of 48 treatment cycles upon 32 couples with mild male factor subfertility no significant difference were found between the two sperm preparation techniques in terms of clinical (% 5.3 vs %6.9, p > 0.05) and ongoing (% 5.3 vs %6.9, p > 0.05) pregnancy rates per cycle. CONCLUSION The gradient technique significantly improves clinical outcome in IUI cycles of unexplained subfertile couples when compared to swim up technique. In male subfertile patients, both techniques yield similar clinical outcomes.

Abstract
For years, the management and treatment of male factor infertility has been 'experience' and not 'evidence' based. Although not evidence-based, current clinical practice involves extensive use of assisted reproductive techniques (ART). Where specific treatments are not indicated or have failed, ART have become popular adjunctive treatments for alleviating male factor infertility. According to the limited evidence available, intrauterine insemination (IUI) may be considered as a first-line treatment in a couple in which the female partner has a normal fertility status and at least 1×10(6) progressively motile spermatozoa are recovered after sperm preparation. If no pregnancy is achieved after 3-6 cycles of IUI, optimized in vitro fertilization (IVF) can be proposed. When less than 0.5×10(6) progressively motile spermatozoa are obtained after seminal fluid processing or sperm are recovered surgically from the testis or epididymis, intracytoplasmic sperm injection (ICSI) should be performed. Although the outcome of no other ART has ever been scrutinized as much before, no large-scale 'macroproblems' have as yet been observed after ICSI. Yet, ICSI candidates should be rigorously screened before embarking on IVF or ICSI, and thoroughly informed of the limitations of our knowledge on the hereditary aspects of male infertility and the safety aspects of ART.

Abstract
Sperm retrieval techniques form an integral part of the assisted reproductive programme. The success of sperm separation is measured by the number of motile sperm retrieved from a given semen sample. The study aimed to evaluate the effect of temperature during sperm preparation events on the number and percentage motile sperm retrieved following a double wash swim-up procedure. Thirty semen samples were obtained from 10 normozoospermic donors. After collection samples were divided into two aliquots, one aliquot was placed in an incubator at 34 °C, while the second aliquot was left at room temperature (25 °C). Sperm motility assessments were recorded with a computer assisted sperm analyser. Motile sperm fractions were retrieved from the semen samples following a double wash swim-up technique. Two tubes were prepared for each experiment. Tubes were placed in two different centrifuges: (i) SpermFuge (Shivani Industries, India) with temperature centrifuge control (34 °C) and (ii) Sigma with no temperature control facilities. Both centrifuges were set at 484 g for 5 min. Following the second wash, sperm pellets were layered with culture medium, and sperm was allowed to swim up. Supernatants were removed and analysed for sperm concentration and motility values. Percentage motile sperm was transformed to ARCSIN values and results of the two centrifugation methods at 34 °C and room temperature were compared with Mann-Whitney test for independent samples. The mean sperm concentration retrieved at 34 °C was 43.8 ± 50 (SpermFuge) and 32.7 ± 21 (Sigma) (P < 0.05), compared to retrieved concentration at room temperature namely, 30.9 ± 33 (SpermFuge) and 30.6 ± 17 (Sigma) (P ≥ 0.05). The mean percentage motile sperm at 34 °C was 64.0 ± 19 (SpermFuge) and 44.2 ± 24 (Sigma) (P = 0.02), while at room temperature the percentage motile sperm was 54.7 ± 17 (SpermFuge) compared to 46.5 ± 14 (Sigma) (P ≥ 0.05). Centrifuge temperature and incubation temperature significantly influenced the percentage retrieved motile sperm. The use of temperature-controlled sperm preparation might have clinical value for men with poor sperm motility values.

Abstract
Objective. There is an asymmetric allocation of technology and other resources for infertility services. Intrauterine insemination (IUI) is a process of placing washed spermatozoa transcervically into the uterine cavity for treatment of infertility. This is a review of literature for the potential use of IUI as a basic infertility treatment in technology-limited settings. Study design. Review of articles on treatment of infertility using IUI. Results. Aspects regarding the use of IUI are reviewed, including ovarian stimulation, semen parameters associated with good outcomes, methods of sperm preparation, timing of IUI, and number of inseminations. Implications of the finding in light of the needs of low-technology medical settings are summarized. Conclusion. The reviewed evidence suggests that IUI is less expensive, less invasive, and comparably effective for selected patients as a first-line treatment for couples with unexplained or male factor infertility. Those couples may be offered three to six IUI cycles in technology-limited settings.

Abstract
Semen availability in ram semen processing facilities is of great importance for the genetic improvement of sheep. Accordingly, any method that would increase sperm viability in low viability ejaculates could be useful. In this study, the possibility of a glass beads filtration method by estimating the beads total surface provided (TSP) for adhesion of spermatozoa, was evaluated. Initially, two different TSP (102 and 154 cm(2)) achieved by various sizes of beads (1500, 2000 and 3000 microm) were tested and no significant difference in sperm viability improvement was noticed for the same TSP by different beads (p > 0.05). Next optimization tests were performed in which three different funnels were used for filtration at a standard TSP (154 cm(2)). The pear-shaped funnel was found to be the most appropriate for filtration, as semen volume recovery and sperm viability improvement were more pronounced (p < 0.05). Finally, filtration tests were conducted with pear-shaped funnels with different TSP (102 and 154 cm(2)) obtained by the aforementioned beads sizes (1500, 2000 and 3000 microm) in equal aliquots. Total surface provided of 102 cm(2) proved to be the more appropriate for filtration than 154 cm(2), as shown by the significant improvement of sperm viability (p < 0.01) and the significantly higher filtrate semen volume (p < 0.05). In conclusion, ram sperm viability improvement by more than 20% of its initial value and semen volume recovery by more than 60%, along with the fact that the total filtration time did not exceed 6 min in any case, suggest that through further development this method could be successfully used during ram semen processing.

Abstract
BACKGROUND Semen preparation techniques for assisted reproduction, including intrauterine insemination (IUI), were developed to separate the motile morphological normal spermatozoa. Leucocytes, bacteria and dead spermatozoa produce oxygen radicals that negatively influence the ability to fertilize the egg. The yield of as many motile, morphologically normal spermatozoa as possible might influence treatment choices and therefore outcomes. OBJECTIVES To compare the effectiveness of gradient, swim-up, or wash and centrifugation semen preparation techniques on clinical outcome in subfertile couples undergoing intrauterine insemination (IUI). SEARCH STRATEGY We searched the Menstrual Disorders and Subfertility Group Trials Register (13 January 2007), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 2), MEDLINE (1966 to January 2007 ), EMBASE (1980 to January 2007), Science Direct Database (1966 to January 2007), National Research Register (2000 to 2007), Biological Abstracts (2000 to January 2007), CINAHL (1982 to October 2006) and reference lists of relevant articles. We also contacted experts and authors in the field. SELECTION CRITERIA Parallel randomized controlled trials (RCTs) comparing the efficacy of semen preparation techniques used for subfertile couples undergoing IUI in terms of clinical outcome were included. DATA COLLECTION AND ANALYSIS Two reviewer authors independently assessed trial quality and extracted data. Study authors were contacted for additional information. MAIN RESULTS Five RCTs, including 262 couples in total, were included in the meta-analysis (Dodson 1998; Grigoriou 2005; Posada 2005; Soliman 2005; Xu 2000). Xu compared the three techniques; Soliman compared a gradient technique versus a wash technique; Dodson and Posada compared a gradient technique versus a swim-up technique; whereas Grigoriou compared swim-up versus a wash technique. No trials reported the primary outcome of live birth. There was no evidence of a difference between pregnancy rates (PR) for swim-up versus a gradient or wash and centrifugation technique (Peto OR 1.57, 95% CI 0.74 to 3.32; Peto OR 0.41, 95% CI 0.15 to 1.10, respectively); nor in the two studies comparing a gradient technique versus wash and centrifugation (Peto OR 1.76, 95% CI 0.57 to 5.44). There was no evidence of a difference in the miscarriage rate (MR) in two studies comparing swim-up versus a gradient technique (Peto OR 0.13, 95% CI 0.01 to 1.33). AUTHORS' CONCLUSIONS There is insufficient evidence to recommend any specific preparation technique. Large high quality randomised controlled trials, comparing the effectiveness of a gradient and/ or a swim-up and/ or wash and centrifugation technique on clinical outcome are lacking. Further randomised trials are warranted.

Abstract
OBJECTIVE The hemizona assay (HZA) is an established functional test that examines in vitro sperm-zona pellucida binding capacity with high predictive power for fertilization outcome in IVF. The objective of this study was to evaluate the value of the HZA as a predictor of pregnancy in patients undergoing controlled ovarian hyperstimulation (COH) and intrauterine insemination (IUI). DESIGN Prospective clinical study. SETTING Academic center. PATIENT(S) Eighty-two couples with unexplained or male factor infertility that underwent 313 IUI cycles. INTERVENTION(S) Basic semen analysis and HZA were performed within three months of starting COH/IUI therapy. MAIN OUTCOME MEASURE(S) Hemizona index (HZI) and clinical pregnancy. RESULT(S) Overall, patients with an HZI of <30 had a significantly lower pregnancy rate compared to patients with an HZI of > or =30 (11.1% vs. 40.6%, respectively; P<.05; relative risk for failure to conceive: 1.5 (confidence interval 1.2-1.9)). In all patients combined, and in the range of HZI 0-60, the duration of infertility (P=.000) and the HZI (P=.004) were significant determinants of conception (receiver operating characteristics (ROC) analysis). In couples with male infertility, the average path velocity and HZI were significant predictors of conception (P=.001 and P=.005, respectively, ROC analysis). The negative and positive predictive values of the HZA for pregnancy were 93% and 69%, respectively. Logistic regression analysis provided models of HZI (P=.021) and duration of infertility (P=.037) with highest predictability of conception in male factor and unexplained infertility groups, respectively. CONCLUSION(S) The HZA predicted pregnancy in the IUI setting with high sensitivity and negative predictive value in couples with male infertility. Results of this sperm function test are useful in counseling couples before allocating them into COH/IUI therapy.

Abstract
PURPOSE To evaluate the outcome of women with hypogonadotropic hypogonadism undergoing in-vitro fertilization (IVF). METHODS We retrospectively assessed outcomes in 58 women with hypogonadotropic hypogonadism (HH) and, as matched controls, in 116 women with tubal factor (TF) infertility who underwent assisted reproduction treatment (ART). For ovulation induction, human menopausal gonadotropin (hMG) was used in HH patients and a combination of hMG and gonadotropin releasing hormone (GnRH) agonist was used in TF patients. Conception and implantation rates, as well as duration of stimulation and number of oocytes retrieved, were the main outcome measures. RESULTS Of the 58 HH patients, 53 (91.3%) responded adequately to ovulation induction and underwent ET. A larger amount of gonadotropins and a longer duration of ovarian stimulation were needed in HH patients than in TF patients. The mean number of retrieved oocytes and implantation rates did not differ between the groups. In addition, there were no differences between the HH and TF groups in pregnancy (53.8 vs. 48.6%) and multiple pregnancy (63.4 vs. 48.4%) rates. In the HH group, the miscarriage rate was 3.4%, and none of these patients developed severe OHSS. CONCLUSION IVF in HH patients, in which there was a background of previous failed ovulation induction, was as successful as in women with TF infertility.

Abstract
PURPOSE OF REVIEW Intrauterine insemination with or without superovulation is the initial step in assisted reproductive technologies. There have been many attempts to increase the efficiency of this route. One approach may be to increase the frequency of insemination. In the last decade, there has been a continuing debate regarding the increased efficiency of IUI with double IUI. RECENT FINDINGS Although the initial studies showed that superovulation with double intrauterine insemination had better pregnancy rates than with a single application, recent studies found that ovarian stimulation with double insemination has not increased the pregnancy rates. SUMMARY Superovulation with intrauterine insemination is a treatment modality used in unexplained infertility and mild male infertility. Increasing the efficiency of the technique has always been an interest of research. Double intrauterine insemination has been suggested to increase efficiency; recent studies, however, have not confirmed this finding.

The yield of as many motile, morphologically normal spermatozoa might influence treatment choices and therefore outcomes. OBJECTIVES To compare the effectiveness of gradient, swim-up, or wash and centrifugation in subfertile couples undergoing intrauterine insemination (IUI) on clinical outcome as well as on semen parameters. SEARCH STRATEGY We searched the Menstrual Disorders and Subfertility Group's trials register (30 June 2003), MEDLINE (1966 to July 2003), EMBASE (1980 to July 2003), Science Direct Database (1966 to July 2003), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 3, 2003), National Research Register (2000 to Issue 2, 2003), Biological Abstracts (2000 to June 2003), CINAHL (1982 to July 2003) and reference lists of relevant articles. We also contacted experts and authors in the field. SELECTION CRITERIA Parallel randomised controlled trials (RCTs), comparing the efficacy of semen preparation techniques used for subfertile couples undergoing IUI, were included. RCTs or split sample studies examining semen parameters after different semen preparation techniques were also included. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality and extracted data. Study authors were contacted for additional information. MAIN RESULTS Two randomised controlled trials comparing clinical outcomes, including 81 participants in total, were included in the meta-analysis (Dodson 1998-I/ II; Xu 2000-I/ II). Both studies compared swim-up technique versus gradient technique in 65 subfertile couples undergoing IUI. One study compared the effectiveness of both techniques with wash technique. No trials reported the primary outcome of live birth. There was no statistically significant difference between pregnancy rates (PR) for swim-up versus gradient / wash centrifuge (Peto OR 0.55, 95% CI 0.17 to 1.76; Peto OR 1.74, 95% CI 0.2 to 14.9; PR/ couple swim-up 20%, gradient 40%, wash 12.5%) or gradient versus wash centrifuge (Peto OR 4.01, 95% CI 0.82 to 19.56; PR/ couple swim-up 15%, gradient 20%). There was no significant difference in the miscarriage rate (MR) per couple between either of the three treatment groups in the one trial reporting this outcome (MR/ couple swim-up 0%, gradient 10.3%, wash 0%. MR/ pregnancy gradient 30.3%). There was no statistically significant difference in the multiple pregnancy rate (MPR) per couple between either of the three treatment groups in Dodson 1998-I/ II (MPR/ couple swim -up 0%, gradient 0%, wash 6.3%). One triplet pregnancy was recorded. Fifteen studies comparing semen parameters after processing were included. Two studies were included in the meta-analysis, we were not able to pool results. REVIEWERS' CONCLUSIONS There is insufficient evidence to recommend any specific preparation technique. Large high quality randomised controlled trials, comparing the effectiveness of a gradient and/ or a swim-up and/ or wash and centrifugation technique on clinical outcome are lacking. Further randomised trials are warranted. Results from studies comparing semen parameters may suggest a preference for gradient technique, but firm conclusions cannot be drawn and the limitations should be taken into consideration.
