Abstract Background: Although it is well documented on the study of intrauterine insemination (IUI), the effectiveness of various factors on IUI treatment is inconsistent. The aim of this study is to investigate the various factors that influence IUI outcome and attempt to set up optimal protocol for IUI patients. Methods: This was a retrospective cohort study including1948 cycles (843 couples) that performed IUI between January 2012 and December 2013 in a single centre. Various factors that may affect IUI outcome were analyzed using chi-square. Moreover, we conducted multiple logistic regression to evaluate the main factors on the effects of IUI outcome. In addition, follicle growth and endometrial development relevant to conception were also assessed among protocols. Results: The clinical pregnancy rate (CPR) per cycle was 12.5% in the present study. Seven factors were identified to be associated significantly with CPR by multivariate logistic regression analysis: female age, type of infertility, ovarian stimulation protocol, preovulatory follicles, endometrial thickness, growing length of preovulatory follicle, post-washed total motile spermatozoa count (TMSC). Comparing with 11 days or less, more than 15 days for ovarian response and endometrial development before insemination induced a better success rate. Although ovarian stimulation with gonadotrophin or letrozole induced higher CPR when comparing to stimulation with clomiphene citrate or without stimulation, ovarian stimulation with letrozole was superior to gonadotrophin by its similar CPR to gonadotrophin but lower follicle number, without the risk of multiple pregnancy. Women younger than 41 years with elevated endometrial thickness inseminated with TMSC ≥ 4.0 million had better chance to obtain pregnancy. Number of treatment cycle was not a factor to affect CPR, with a stable CPR in the first four cycles. Conclusions: We conclude that women no more than 41 years old are suitable to perform at least 4 cycles of IUI before proceeding to IVF. The optimized IUI treatment requires ovarian stimulation with letrozole to induce one/two follicles and fertilize with four or more million motile spermatozoa and an elevated endometrium on day 15 or after in the cycle. Key words: infertility, intrauterine insemination, effective factors, clinical pregnancy rate.

Abstract Background Some studies have stated that intrauterine insemination (IUI) with controlled ovarian stimulation (COS) might increase the pregnancy rate, while others suggest that IUI in the natural cycle (NC) should be the first line of treatment. It remains unclear whether it is necessary to use COS at the same time when IUI is applied to treat isolated male factor infertility. Thus, we aimed to investigate efficacy of IUI with COS for isolated male factor infertility. Methods A total of 601 IUI cycles from 307 couples who sought medical care for isolated male factor infertility between January 2010 and February 2020 were divided into two groups: NC-IUI and COS-IUI. The COS-IUI group was further divided into two subgroups according to the number of pre-ovulatory follicles on the day of HCG: cycles with monofollicular development (one follicle group) and cycles with at least two pre-ovulatory follicles (≥ 2 follicles group). The IUI outcomes, including clinical pregnancy, live birth, spontaneous abortion, ectopic pregnancy, and multiple pregnancy rates were compared. Results The clinical pregnancy, live birth, spontaneous abortion, and ectopic pregnancy rates were comparable between the NC-IUI and COS-IUI group. Similar results were also observed among the NC-IUI, one follicle, and ≥ 2 follicles groups. However, with respect to the multiple pregnancy rate, a trend toward higher multiple pregnancy rate was observed in the COS-IUI group compared to the NC-IUI group (8.7% vs. 0, P = 0.091), and a significant difference was found between the NC-IUI and ≥ 2 follicles group (0 vs. 16.7%, P = 0.033). Conclusion In COS cycles, especially in those with at least two pre-ovulatory follicles, the multiple pregnancy rate increased without a substantial gain in overall pregnancy rate; thus, COS should not be preferred in IUI for isolated male factor infertility. If COS is required, one stimulated follicle and one healthy baby should be the goal considering the safety of both mothers and foetuses.

Objective: To compare the efficacy of clomiphene citrate and letrozole in combination with low dose human menopausal gonadotropin for controlled ovarian stimulation in intrauterine insemination (IUI) cycles.Methods: During January-2018 to December-2019 for intending 496 IUI cycles, controlled ovarian stimulation was performed with either clomiphene or letrozole combined with human menopausal gonadotropin (hMG), in two arms:  subjects in one arm (Group A) were with clomiphene and hMG in 222 cycles; those in the second arm (Group B) were with letrozole and hMG in 274 cycles. Pregnancy rate and clinical pregnancy rate of both groups were considered as the primary outcomes.Results: Patient characteristics like female age, indications for IUI, type of IUI, endometrial thickness and total motile fraction (TMF) of spermatozoa of male partners were seen similar in both groups. The letrozole-hMG group (Group B) had significantly higher numbers of cycles with single dominant follicle (P=0.01) and human chorionic gonadotropin (hCG) was more frequently used as the ovulation trigger (P=0.03). Pregnancy rate (18.5% vs. 15.3%, P=0.35) and clinical pregnancy rate (18.5% vs. 15.3%, P=0.35) were similar in groups A and B, respectively.Conclusion: Clomiphene citrate and letrozole combined with low dose human menopausal gonadotropin were equally effective for controlled ovarian stimulation in IUI cycles.

ABSTRACT Objectives To determine the predictive factors for pregnancy after stimulated intrauterine insemination (IUI). Materials and methods A retrospective analysis of 136 patients undergoing 443 stimulated IUI cycles was done in an attempt to identify significant variables predictive of treatment success. The primary outcome measures were clinical pregnancy and live birth rates. Predictive factors evaluated were female age, duration of infertility, indication for IUI, number of preovulatory follicles, and postwash total motile fraction (TMF). Results The overall clinical pregnancy rate and live birth rate were 7.2% and 5.1 per cycle respectively. The mean number of IUI cycles per patient was 3.2, the miscarriage rate was 15%, and the multiple pregnancy rate was 3.1%. Among the predictive factors evaluated, female age (age > 37 years; p = 0.039), the duration of infertility (5.36 vs 6.71 years, p = 0.032), and the TMF (between 10 and 20 million, p = 0.003) significantly influenced the clinical pregnancy rate. Conclusion The clinical management of the selected infertile couple should be performed in an expedited manner taking into consideration the age of the woman, etiology, and duration of infertility and motile fraction of sperms.

Abstract Background The cause of infertility has not been found in unexplained infertile patients,, and perhaps one of the possible reasons is impairment of fetal implantation, as well as the multiple role of GCSF in improving implantation and quality of blastocyst. Therefore, the aim of this study was to investigate the role of GCSF in the pregnancy rate of patients undergoing IUI.Methods The patients with unexplained infertility were divided into two groups: one group was received GCSF in their IUI cycle and the other group had the routine IUI. Both groups were stimulated by letrozole, metformin, and monotropin during the cycle. When at least one follicle was greater than 18 mm, 5000 IU hCG intramuscularly was administered for ovulation induction and IUI was performed 34–36 hours later. In intervention group, 300 ug GCSF subcutaneously administrated in two days after IUI. Biochemical pregnancy rate was evaluated two weeks after IUI and clinical pregnancy rate was identified by the presence of a gestational sac on ultrasonography 8 weeks after IUI.Results There was no significant difference in demographic and clinical characteristics between the two groups. The chemical pregnancy rate(16.3% vs 12.2%) and the clinical pregnancy rates (16.3% vs 8.3%) were improved in patients receiving GCSF compared to controls, but these differences was not significant (P = 0.56) and (P = 0.21).Conclusion Systemic administration of a single dose of 300 µg GCSF subcutaneously two days after IUI may slightly improve clinical pregnancy rate in patients with unexplained infertility. Nevertheless, our findings do not support routine use of G-CSF in unexplained infertility women with normal endometrial thickness.

Abstract Study question Does GCSF by intrauterine route leads to better result in the treatment of thin endometrium as compared to GCSF by the subcutaneous route, in IVF-ICSI Cycles? Summary answer Yes, GCSF by intrauterine route leads to better result in the treatment of thin endometrium as compared to subcutaneous-GCSF, in ART Cycles? What is known already GCSF, is a member of the colony stimulating factor family of cytokines and growth factors. GCSF receptors are expressed in high concentration on dominant follicle, particularly at preovulatory stage.The endometrium also shows an increased expression of these receptors. GCSF concentration rises in the follicular fluid at the same time. Serum levels of GCSF are found to be in direct correlation with levels of GCSF in follicular fluid. Serum levels increase progressively from the day the embryo-transfer to the day of implantation. GCSF has been found to be beneficial in patients with thin endometrium and recurrent implantation failure. Study design, size, duration This was a RCT conducted between 2018–2019. 30 patients with thin endometrium were enrolled in each group. In either group, GCSF was given if endometrium was less than 7mm on day 14, maximum of two doses were administered. Patients undergoing frozen embryo transfer were recruited in the study, after meeting the inclusion and exclusion criteria. Primary outcome measured was increase in endometrium thickness and the secondary outcome was the clinical pregnancy rate and abortion-rate. Participants/materials, setting, methods 60 patients with thin endometrium were randomly divided into two groups. Group A: Inj. GCSF (300 mcg/1 ml) subcutaneously on Day 14 onwards alternate days for two doses. Group B: Inj. GCSF (300 mcg/1 ml) instilled slowly into the uterine cavity using an intrauterine insemination (IUI) catheter under USG guidance. Endometrial thickness was assessed after 48 h. If endometrial thickness was found to be < 7 mm, a second infusion of GCSF was carried out. Main results and the role of chance In the subcutaneous group (group-A) the mean endometrial thickness before GCSF injection was 5.8 ± 0.6 mm and, after injection it increased to 6.9 ± 0.4 mm. Similarly, in the intrauterine group (group-B) the mean endometrial thickness before GCSF was 5.9 ± 0.7 which increased to a mean of 7.9 ± 0.5 after GCSF instillation. The difference between endometrial thickness before and after intrauterine infusion of GCSF was more than that in the subcutaneous group. In group-A, 08 patients conceived out of 30 patients ( clinical pregnancy rate 26.6%) and in group B 11 conceived out of 30 patients in whom GCSF was instilled intrauterine (pregnancy rate 36.6%). Thus, there was a difference in the clinical pregnancy rate in the two groups, the intrauterine group yielding a higher clinical pregnancy rate, but it was not statistically significant. Because of the thin endometrium, we found an abortion rate of 25% (2/8) in the subcutaneous-GCSF group, and an abortion rate of 18% (2/11) in the intrauterine GCSF group. Limitations, reasons for caution There are few potential limitations because of the small sample size. Confounders such as obesity, smoking and alcohol intake, presence of adenomyosis and endometriosis, were not taken into consideration. Though prevalence of obesity is usually low in Indian women. Habits of smoking and alcohol are exceedingly uncommon in Indian women. Wider implications of the findings: Use of GCSF plays an important role in management of patients of thin endometrium undergoing embryo transfer. It is an easily available and economical preparation in developing countries and the intrauterine instillation of GCSF can be easily practiced in an ART unit with good results in resistant thin endometrium patients.
