A randomized controlled trial of Eye Movement Desensitization and Reprocessing (EMDR) Therapy in the treatment of fibromyalgia.

Background: In addition to pharmacological treatment, psychotherapeutic approaches are recommended for the treatment of fibromyalgia. There is a suggestion that eye movement desensitization and reprocessing (EMDR) therapy may be effective. This study aimed to investigate the impact of EMDR therapy on fibromyalgia symptoms, depression, sleep quality, and traumatic stress in fibromyalgia patients through a randomized controlled study (RCT). Materials and methods: The sample for this study comprised 79 individuals diagnosed with fibromyalgia. Participants were randomly assigned to two groups: the "Treatment as Usual" (TAU) group and the TAU + EMDR group. Prior to the study and at six different time points (before starting the study, at the end of the 5th, 10th, and 15th sessions, 1 month later, and 3 months later), participants completed assessments, including the Fibromyalgia Impact Questionnaire (FIQ), Visual Analog Scale (VAS), Fibromyalgia ACR 2010 Diagnostic Criteria [Widespread Pain Index (WPI) and Symptom Severity Scale (SSS)], Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), and Trauma Symptom Checklist-40 (TSC-40). Results: There were no differences in the sociodemographic variables between the study and experimental groups. Analysis of variance revealed a statistically significant group effect on VAS (p = 0.019), WPI (p = 0.018), BDI (p = 0.019), and TSC-40 (p = 0.21). After applying Bonferroni correction, EMDR was found to be effective for VAS, WPI, SSS, BDI, PSQI, and TSC-40 (p <0.05). Conclusion: The results of the current study suggest that EMDR therapy is a viable alternative treatment for fibromyalgia. We believe these findings offer robust evidence supporting the efficacy of EMDR therapy in treating fibromyalgia, particularly in the context of a randomized controlled trial (RCT). The application of EMDR therapy for the treatment of patients with fibromyalgia is likely to be beneficial. Clinical trial registration: ClinicalTrials.gov, identifier NCT06265194.

Surgical treatment and outcomes of intramedullary tumors by minimally invasive approach: Answer.

The surgical outcomes which evaluated in studies depend on preoperative condition, demographic data of patients, surgical approaches or treatment and local factors. Author argues that the neurological deterioration rate 4,2% which is reported in our study is marvelous and he exemplifies the other studies in literature. Neurosurgeons know that the clinical studies in literature do not compare only their results. Authors compare and evaluate studies with preoperative demographic data, surgical approach, local factors or others between their results. Therefore this detail explains paralogism of the author. The neurological deterioration rate is reported as smaller or similar in our study to the contrary of others due to all the preoperative demographical data were evaluated with others. We suppose the author alludes that the neurological deterioration rate is marvelous since he does not compare all of the demographical data in these clinical studies.

Surgical treatment and outcomes of intramedullary tumors by minimally invasive approach.

Intramedullary tumors are uncommon neoplasms which, without treatment, can cause neurologic morbidity or mortality. The goal of the treatment is complete surgical resection with a minimally invasive approach while preserving neurological status and also spinal stability. Out of 1972 patients with tumors of the spinal canal treated between 1994 and 2017, 168 intramedullary tumors of 417 intradural tumors have been presented. All patients had undergone one surgical resection. The mean age is 43 ± 12 years (range 11-67 years). Tumors were subdivided into 4 groups: cervically located-tumors (n = 43), cervicothoracic-region-tumors (n = 32), thoracic-region-tumors (n = 57), and lumbosacral-region-tumors (n = 36). The mean follow-up time was 37 ± 29 months. Gross-total resection rate was higher in cervical located intramedullary tumors compared to the thoracic intramedullary tumors. Cervical intramedullary tumors showed better postoperative functional outcome than the thoracic intramedullary lesions. In intramedullary tumors, extending more than 3 spinal segments, postoperative worsening was significantly increased. A minimally invasive approach (the bilateral decompression via unilateral hemilaminectomy) was used to remove the tumor while preserving spinal stability. Perioperative permanent morbidity was very low. Intramedullary tumors should be surgically treated as soon as neurological symptoms appear. Patients with thoracic intramedullary tumors and tumor extension of more than three segments were at a higher risk for permanent morbidity. The minimally invasive approach allowed complete removal of the intramedullary tumors, and adequate preservation of vertebral stability while providing a good postoperative course.

Surgical Outcomes of Extraforaminal Microdiskectomy by Midline Incision for Far-Lateral Lumbar Disk Herniation.

BACKGROUND: Far-lateral lumbar disk herniation (FLDH) is defined as a disk herniation located laterally to the medial wall of the pedicle. The aim of our study is to describe the extraforaminal microdiskectomy by midline incision for FLDH, which does not include laminotomy-partial facetectomy, and to evaluate mid-term surgical outcomes. METHODS: 107 patients who underwent surgery for FLDH by midline incision for the first time between 2012 and 2017 were included in our study. The assessment of neurological status of the patients was done by physical examination, preoperative Oswestry Disability Index (ODI), Visual Analog Scala (VAS) scores, and magnetic resonance images. They were then followed-up postoperatively and at 12 months with VAS and ODI tests. RESULT: 58 (54.2%) patients were male and 49 (45.8%) were female. The mean age at the time of surgery was 55.0 ± 8.6 years. The mean ODI scale score was 32.4 ± 6.2 preoperatively, 11.4 ± 2.1 early postoperatively, and 9.7 ± 2.2 in late postoperative follow-up (statistically significant, p = 0.001). The average VAS was 7.51 ± 1.1 preoperatively, 2.74 ± 0.7 early postoperatively, and 0.68 ± 0.08 in late postoperative follow-up (statistically significant, p = 0.001). The average operative time was 41 ± 7 (37 to 58) minutes. CONCLUSIONS: The extraforaminal microdiskectomy without laminotomy by midline incision is a minimally invasive approach for FLDH. Our technique allows a sufficient and safe decompression of the neural structures, and thus results in a significant reduction of the symptoms and disability.

Does multifollicular development and number of intermediate follicles contribute to the effect of luteal phase support with vaginal progesterone gel in intrauterine insemination cycles?

Luteal phase deficiency as a result of multifollicular development which produces supraphysiological progesterone and estradiol levels and benefit of luteal phase support have been proven in assisted reproductive technique (ART) treatment. But, there were some controversial results in intrauterine insemination (IUI) cycles whether luteal phase support (LPS) with progesterone have an impact on pregnancy outcome. To assess the efficacy of vaginal progesterone gel in the gonadotropin-induced IUI cycles, this retrospective data analysis compared the luteal phase support and control group in terms of clinical pregnancy (CPR) and live birth rates (LBR). In subgroup analysis, multifollicular and monofollicular growth were analyzed separately. In total, after exclusion criteria, 380 IUI cycles were analyzed, cycles were grouped as LPS(+) and LPS(-) with 190 and 190 cycles, respectively. CPR and LBR were comparable between groups (11.6% vs. 10.5, p = .74 and 8.9% vs. 8.4%, p = .75 respectively). Although multifollicular growth demonstrated higher pregnancy outcomes than monofollicular growth, intermediate follicles (14-16 mm) had a positive impact on pregnancy outcome in monofollicular growth like multifollicular subgroup. We found no difference in CPR and LBR according to the luteal phase vaginal progesterone gel. Nevertheless, multifollicular cycles and also monofollicular growth cycles with two and more intermediate follicles may have benefit LPS in gonadotropin-induced IUI cycles.

Surgical outcome and efficacy of lumbar microdiscectomy technique with preserving of ligamentum flavum for recurrent lumbar disc herniations.

The reoperation for recurrent lumbar disc herniation (LDH) causes difficulties and low surgical outcome. The operation technique which was preferred in the first surgery has gained importance in reoperation for recurrent-LDH. The aim of our study is to evaluate the efficacy of lumbar microdiscectomy technique with preserving of ligamentum flavum (LF) for recurrent lumbar disc surgery. 149 patients were evaluated in two groups in our study, who were treated for single level recurrent-LDH in our clinic. The first group contains 86 patients who were treated by lumbar microdiscectomy without preserving LF during first surgery in other clinics, the second group contains 63 patients who were treated by lumbar microdiscectomy with preserving of LF during first surgery in our clinic. We investigated age, weight, gender, recurrence-time, level-side of recurrent-LDH, the surgical outcomes and hemorrhage, complications, operation-time. The mean-age was 45,9 ±â€¯12,9, 44,1 ±â€¯11,6 years and mean-weight was 73,4 ±â€¯14,4, 77,3 ±â€¯14,2 kg in two groups. 29 patients were treated for L3-4, 63 patients for L4-5, 57 patients were treated for L5-S1 recurrent LDH. The preoperative and follow-up back-leg pain Visual Analogue Scale (VAS), Oswestry Disability Index (ODI) scores decreased significantly in all patients (p < 0,05). The average operation-time was 70,9 ±â€¯5,2 and 42,3 ±â€¯4,6 min and the average surgical hemorrhage was 91,1 ±â€¯11,3 and 50,3 ±â€¯7,4 ml in 1. group and 2. group respectively. Preserving of LF in first surgery is gaining importance for recurrent lumbar disc surgery with protected anatomical structures. Our technique decreases complication, operation time, surgical hemorrhage and provides good surgical outcomes in recurrent lumbar disc surgery.

Ultrasound-Guided Microsurgical Excision for Brachial Plexus Schwannomas: Short-Term Clinical Study.

AIM: To describe the ultrasound-guided microsurgical excision technique and to evaluate the surgical outcomes of brachial plexus schwannomas. MATERIAL AND METHODS: Eleven patients who underwent ultrasound-guided microsurgery for small ( < 3 cm) brachial plexus schwannomas between 2013 and 2017 were included in our study. RESULTS: The mean age of the patients was 45 years (range: 30-68 years), with six tumors localized on the right and five on the left side. There were no perioperative or postoperative complications. No postoperative deficits were observed in the patients. CONCLUSION: Surgeons can safely and completely excise most of the benign ( < 3 cm and non-palpable) brachial plexus tumors by the ultrasound-guided microsurgical excision technique.

Cranio-Orbital Tumors: Clinical Results and A Surgical Approach.

OBJECTIVES: In this study, we aimed to share the surgical approaches and clinical experiences of cranio-orbital tumors, which are surgically difficult anatomies. METHODS: A total of 22 orbital tumors with extraorbital-transcranial pathology between January 2004 and December 2017 were retrospectively reviewed. Information was obtained from hospital, operation and outpatient records for this study. Preoperative demographic data, ophthalmologic examination findings, clinical and radiological findings were recorded. All patients had cranial magnetic resonance and cranial computerised tomography examinations at this time. The location of the tumor, its size and its relation to neighboring structures were recorded in the light of these examinations. RESULTS: The lateral approach was performed in 12 cases. The lateral approach was performed with frontotemporal craniotomy. Because of the lateral inferior location of the tumor in three of 12 cases, zygoma osteotomy was added to classical osteotomy. In 10 cases, the anterior approach was applied and the frontal craniotomy was found sufficient in seven cases. In three cases subfrontal craniotomy was added to classical craniotomy. CONCLUSION: The findings obtained in this study suggest that high resection rates can be achieved with appropriate surgical intervention in orbital tumors requiring a transcranial surgical approach. The most important factor in surgical planning is the location of the tumor. The size of the tumor and the expectation of the percentage of surgical removal are the other important factors. In our series, it has reached high excision ratio in most cases with low complication rate, good visual field and eye movements results.

Midterm outcome of thoracic disc herniations that were treated by microdiscectomy with bilateral decompression via unilateral approach.

Thoracic disc herniation (TDH) surgery carries risks of neurological worsening due to thoracic cord retraction injury. Multiple approaches have been developed aiming for resecting the disc herniations of the thoracic segment. We have conducted a prospective observational study to evaluate the mid-term outcome of thoracic microdiscectomy with bilateral decompression via a unilateral approach (BDUA). Patients were checked pre-operative, post-operative, and late follow-up by Oswestry Disability Index (ODI), Visual Analogue Scale (VAS), and radiological images. Twenty-three patients were treated for TDH by microdiscectomy with BDUA between January 2010 and January 2015. Nine patients were female, fourteen were male, and all of those mean age was 51,2 ±â€¯8,3 (range 29-64 years). The mean follow-up time was 22,04 ±â€¯8,59 months (range 13-58 m). The ODI and VAS scores decreased significantly in both postoperative and late follow-up evaluations. Microdiscectomy with BDUA for thoracic disc herniations allowed sufficient and safe decompression of the neural structures and resulted in a significant reduction of symptoms and disability.

Computerized Tomography-Guided Stereotactic Biopsy of Intracranial Lesions: Report of 500 Consecutive Cases.

AIM: Computed tomography (CT)-guided stereotactic brain biopsy has been performed in our clinic since March 1998. In this prospective study, we examined the patient data undergoing stereotactic biopsy and the results of biopsies in 500 consecutive patients. MATERIAL AND METHODS: Between the dates of March 1998 and January 2015, CT-guided stereotactic biopsies were performed by using the Leksell stereotactic frame system (Elekta Instruments EU, Sweden) in 500 patients. A total of 512 procedures were performed in patients consisting of 184 females (36.8%) and 316 males (63.2%), ages ranging from 3 to 81 years (mean 50.40±16.67). RESULTS: Conclusive histopathological diagnosis was not achieved in 17(3.3%) of 512 procedures. Of the others, 173 (33.8%) were high-grade gliomas, 103 (20.1%) were low-grade gliomas, 36 (7%) were malignant lymphomas, 34 (6.6%) were other types of brain tumors, 82 (16%) were metastasis and 67 (13.1%) were non-tumoral lesions. Complications were occurred in ten cases: 3 tumoral bleedings, 2 hypertensive cerebral hematomas, 2 peroperative convulsions, 1 epidural hematoma, 1 myocardial infarction and 1 brain edema. The patients who developed myocardial infarction and hypertensive thalamic hematoma died. The mortality was 0.4% and morbidity was 1.6% in 512 procedures. CONCLUSION: CT-guided stereotactic biopsy is a reliable and a safe procedure in cases with intracranial lesions when histopathological diagnosis is required for the appropriate treatment.

The effect of health-promoting lifestyle education on the treatment of unexplained female infertility.

OBJECTIVE: This study aimed to reveal the 1) awareness, 2) improvements of a health-promoting lifestyle on women with unexplained infertility having at least one of the risk factors that have been indicated to negatively affect fertility (smoking, body mass index lower than 18.5kg/m2 and more than 25kg/m2, over-exercising or not exercising at all, alcohol consumption, caffeine consumption of more than 300mg/day, and high levels of stress) by means of health-promoting lifestyle education, 3) the effect of this improvement on the result of assisted-reproduction treatment in terms of clinical pregnancy. STUDY DESIGN: 64 women diagnosed with unexplained infertility were divided into a group receiving Health-Promoting Lifestyle (HPL) education and a control group. 1) Risk Factors Questionnaire (BMI, Smoking, Alcohol, Stress, Exercise, Caffeine), 2) Depression, Anxiety and Stress Scale, 3) Health-Promoting Lifestyle Profile II. The health promoting lifestyle was given to the education group. The Risk Factors Questionnaire; Depression, Anxiety, Stress Scale and Healthcare-Promoting Lifestyle Profile II were also administered after the first-second-third month of education but before ART treatment. RESULTS: A statistically significant decrease was found in the average levels of four variables as; BMI (p<0.001)-stress (p<0.001)-caffeine consumption (p<0.001)-lower exercise levels (p<0.001). Moreover, the total number of risk factors that females had between the first and third interview decreased significantly. Clinical pregnancy rate after ART was 12 (46.1%) and 5 (19.2%) in education and control group consequently (p=0.02). CONCLUSION: Health-promoting lifestyle education was found to be effective in reducing the lifestyle risk factors for infertility and increasing the success rates of assisted reproduction treatment by correcting these risk factors.

Effects of nasal continuous positive airway pressure therapy on partners' sexual lives.

To assess sexual functioning in male and female partners before and after nasal continuous positive airway pressure (CPAP) therapy in men with obstructive sleep apnea (OSA). Twenty-one male patients with moderate to severe OSA and erectile dysfunction, and their female partner, were recruited into this prospective study. Males diagnosed with OSA were treated with nasal CPAP therapy for 12 weeks. Women were assessed for sexual functioning using the Female Sexual Function Index (FSFI), and for mood status using the Beck Depression Inventory (BDI), before and after their male partner underwent nasal CPAP therapy. Sexual functioning was assessed in men using the International Index of Erectile Function (IIEF), before and after nasal CPAP therapy. After nasal CPAP therapy for OSA in men, IIEF scores were significantly higher than pre-treatment scores. Total pre- and post-treatment IIEF scores (mean ± standard deviation) were 50.28 ± 15.88 and 65.42 ± 7.47, respectively, P < 0.01. Pre- and post-treatment FSFI scores in women were 21.54 ± 6.62 and 29.94 ± 3.76, respectively, P < 0.01. Pre- and post-treatment BDI scores in women were 14.61 ± 9.69 and 12.42 ± 8.92, respectively, P < 0.01. Following treatment of men with OSA, our data indicate benefits for nasal CPAP therapy on sexual functioning in both the male and female partners. Moreover, our findings indicate that improved sexual function in women after their male partner underwent nasal CPAP also had psychological benefits.

What is the Risk of Metabolic Syndrome in Adolescents with Normal BMI who have Polycystic Ovary Syndrome?

OBJECTIVE: The purpose of this study is to evaluate the effect of polycystic ovarian syndrome (PCOS) on the prevalence of metabolic syndrome (MBS) in adolescent girls with normal BMI. MATERIALS AND METHODS: Our study group consisted of 63 pubertal girls with a BMI less than 25 kg/m(2) who were referred to our center with signs of hirsutism or oligomenorrhea. The diagnosis of PCOS was based on the recent ESHRE/ASRM proposal and required that all 3 of the Rotterdam criteria for diagnosing PCOS in adolescents be met. The control group consisted of 159 pubertal girls matched for age and BMI. Glucose, insulin, testosterone, and sex hormone-binding globulin, free testosterone and all lipid parameters measured. For to diagnose the cases with MBS, modified Cook criteria were used and cases who had at least 3 of 5 criteria's were diagnosed as MBS. RESULTS: Girls with PCOS had higher blood pressure parameters (systolic/diastolic) (P < .01), fasting insulin (P = .007), low-density lipoprotein (P = .017), triglyceride (P = .045), total (P < .001) and free testosterone (P = .001) levels compared to control group. There were more cases who had at least 1 Cook criterion in girls with PCOS compared to the control group but the difference was not significant. However, there were more cases who had MBS in girls with PCOS compared to the control group (P = .02). CONCLUSION: MBS prevalence is higher in normal BMI adolescent girls with PCOS compared to age and BMI matched control group. So as clinicians, we must search for the MBS criteria's in girls with PCOS even if they have a normal BMI.

Vaginal misoprostol versus a rectal nonsteroidal anti-inflammatory drug to reduce pain during Pipelle endometrial biopsies: a prospective, randomized, placebo-controlled trial.

BACKGROUND: To evaluate and compare the efficacy of vaginal misoprostol and a rectal nonsteroidal anti-inflammatory drug (NSAID) on pain relief during Pipelle endometrial biopsies in a placebo-controlled randomized study. METHODS: One hundred and fifty-one women who had an indication for a Pipelle endometrial biopsy were randomized into three groups as follows: group 1, vaginal misoprostol; group 2, rectal NSAID, and group 3, control. After the procedure, the women were asked to record their pain severity on a visual analog scale. The secondary outcome of the study was patient acceptability, and vasovagal symptoms and analgesic requirements after the procedure were also recorded. RESULTS: There were no statistically significant differences in the demographic characteristics of the patients. The primary study outcome was the comparison of the median visual analog scale pain scores of groups 1 and 2 versus group 3 (controls); no statistically significant differences were found (p = 0.502). In addition, the patient acceptability (Likert scale), vasovagal symptoms and analgesic requirements after the procedure were similar among the groups (p = 0.204, 1 and 0.546, respectively). CONCLUSION: Our study did not demonstrate a reduction in pain relief during Pipelle endometrial biopsies for patients receiving vaginal misoprostol or a rectal NSAID when compared to patients receiving placebo treatment.

Follicular fluid and serum vascular endothelial growth factor, interleukin (IL)-1ß and glycodelin concentrations: comparison between long-gonadotropin-releasing hormone (GnRH)-agonist and GnRH-antagonist cycles: a randomized controlled trial.

In this randomized controlled trial, we aimed to examine whether differences exist among patients who underwent assisted reproductive technology treatment with a long-GnRH-agonist compared to a GnRH-antagonist protocol in terms of levels of follicular fluid (FF) and serum concentrations of vascular endothelial growth factor (VEGF), glycodelin and interleukin (IL)-1ß on the day of oocyte pick-up (OPU). In 80 infertile couple with male factor or unexplained infertility, 40 women stimulated with GnRH-antagonist protocol and 40 women with the long-GnRH-agonist protocol. FF and blood serum samples were obtained simultaneously from 80 women during the OPU procedure and the concentrations of VEGF, IL-1ß and glycodelin were measured with commercially available kits. Concentrations of FF VEGF, IL-1ß and glycodelin were not significantly different in the long-GnRH-agonist and GnRH-antagonist groups, and neither were serum concentrations of VEGF, IL-1ß and glycodelin. According to our results in at least, we can say that minor differences between these protocols in terms of clinical pregnancy do not depend on VEGF, glycodelin or IL-1ß.

Frequency and determinants of urogenital symptoms in postmenopausal Islamic women.

OBJECTIVE: The objective of this study was to evaluate the frequency of genitourinary symptoms and their relationships with several factors in a large cohort of postmenopausal women in Turkey. METHODS: We performed a cross-sectional study to review genitourinary complaints among 1,328 postmenopausal women; 1,071 of these women were enrolled in the study. They were questioned about their vaginal and urinary symptoms, and the relationships between these symptoms and their demographic characteristics were evaluated. RESULTS: The most common vaginal and urinary symptoms were dryness (n = 358; 33.4%) and nocturia (n = 421; 39.3%), respectively. Cigarette smoking and regular exercise were not associated with any vaginal symptoms (P > 0.05), with the exception of an association between regular exercise and vaginal dryness (P = 0.026). Nocturia was more common in women older than 60 years (P = 0.001) and in obese women (P = 0.013). Based on multiple binary logistic regression analysis, lower educational status (primary school vs secondary school or higher) and higher parity were the factors most significantly associated with the appearance of at least three vaginal symptoms. Lower educational status was associated with vaginal pain (P = 0.002; odds ratio [OR], 1.75), itching (P < 0.001; OR, 1.23), and discharge (P = 0.011; OR, 1.46). Higher parity was associated with vaginal itching (P < 0.001; OR, 1.23), discharge (P = 0.07; OR, 1.18), and burning (P = 0.012; OR, 1.16). Body mass index (BMI) was the only factor that was significantly associated with the appearance of at least three urinary symptoms, with each one-unit increase in BMI increasing the risk of urgency (P < 0.001; OR, 1.06), nocturia (P < 0.001; OR, 1.06), and frequency (P = 0.009; OR, 1.04). CONCLUSIONS: We identify associations between the frequency of genitourinary complaints and educational status, parity, and BMI. There is no association between regular exercise and urogenital symptoms. However, prospective studies are needed to evaluate the effects of regular exercise on urogenital symptoms. When examining postmenopausal women with risk factors for urinary and vaginal symptoms, clinicians should evaluate these symptoms more thoroughly to facilitate earlier treatment.

Factors predictive of clinical pregnancy in the first intrauterine insemination cycle of 306 couples with favourable female patient characteristics.

The objective of this study was to evaluate the factors predictive of clinical pregnancy in the first superovulation/intrauterine insemination (SO/IUI) cycle of couples with favourable female characteristics. We analyzed retrospectively the first SO/IUI cycle of 306 infertile couples with mild male factor infertility and unexplained infertility. The women had a favourable prognosis in terms of ovarian reserve. Univariate logistic regression analyses identified body mass index (BMI) [odds ratio (OR) = 0.9, P = 0.014], sperm concentration [OR = 1.007, P = 0.007] and inseminating motile sperm count (IMC) [OR = 1.007, P = 0.032] as significant predictive factors of clinical pregnancy. Multivariate logistic regression analysis identified BMI [OR = 0.87, P = 0.008] and sperm concentration [OR = 1.008, P = 0.011] as significant factors. Pregnant and non-pregnant groups did not differ significantly in terms of the age and smoking status of the woman, duration and type of infertility, length of the stimulation, total gonadotropin dosage or antral follicle count. Of the female characteristics investigated, BMI was the most significant predictive factor of clinical pregnancy in the first SO/IUI cycle of couples with unexplained or mild male factor infertility and favourable female characteristics. In overweight women, weight loss should be advised before starting SO/IUI. Sperm concentration and IMC were significant male predictive factors for clinical pregnancy in the first SO/IUI.
