Abstract
OBJECTIVE To evaluate the predictive value of sperm morphology, specifically teratospermia, seen during initial semen analysis on the success of intrauterine insemination (IUI) cycles and pregnancy outcomes. METHODS A retrospective cohort analysis on patients undergoing IUI at a large US fertility network. Baseline demographic characteristics, primary infertility diagnoses, and pregnancy outcomes were recorded. A total of 27,925 IUI cycles in 16,169 unique patients were analyzed. IUI cycles were grouped by a sperm morphology of 1% (n = 3799), 2% (n = 5506), 3% (n = 4857), or 4% or greater (n = 13,763). The outcome measures were pregnancy rate (positive pregnancy test), clinical pregnancy rate (CPR) (ultrasound confirmation of a gestational sac with a yolk sac around 5-6 weeks), live birth rate, and miscarriage rate. RESULTS Sperm morphology is a significant predictor of pregnancy rate (P = <.001), CPR (P =.011), and live birth rate (P = .026) following IUI. In each of these outcome measures, patients with 1% normal forms had the lowest percentage of success, and patients with 4% or greater normal forms had the most success. Relative outcome percentages, however, were similar in each group. Live birth rates in the 1%, 2%, 3%, and >4% group were 12.3%, 13.1%, 12.7%, and 13.9%, respectively. Sperm morphology is not a significant predictor of miscarriage rate per clinical pregnancy post-IUI (P = .054). CONCLUSION Sperm morphology was a statistically significant predictor of pregnancy, clinical pregnancy, and live birth but not miscarriage rate after an IUI cycle. Higher morphology percentages were associated with increasingly favorable outcomes. However, the small observed differences did not demonstrate clinical significance.

Abstract
Objective To better understand the impact of sperm morphology on fertility by assessing sperm morphology in a population of known fertile men. Design A prospective cohort study. Setting Fertility center associated with the university. Patients Healthy men >18 years of age were recruited to provide one semen sample before a vasectomy appointment scheduled between March 2020 and November 2022. Patients were included in the study when they had at least one biologic child and no history of difficulty achieving pregnancy or fertility procedures. Interventions None. Main Outcome Measures Sperm morphology. Results A total of 68 patients (mean age 36.7 years) were included. Thirty-eight (55.9%) patients had 3% or lower normal sperm morphology, including two patients who had 0 normal morphology. The most common morphologic abnormalities were head-shaped defects (n = 59, 84.3%), followed by coiled tails (n = 14, 20.3%). Count, concentration, motility, and progressive motility were normal in >90% of patients. Conclusions More than half (55.9%) of fertile male patients had lower than normal sperm morphology in our study. The results of our study further question the clinical relevance of sperm morphology on fertility outcomes and when the current approach in assessing morphology is too strict.

Abstract
Objective To determine the impact of abnormal sperm morphology of the pre-washed semen sample on the day of intrauterine insemination (IUI) on clinical pregnancy rates (CPR). Design Cross sectional retrospective chart review. Setting Academic fertility center. Patients Couples undergoing (IUI) from May 2014 to March 2022. Interventions Sperm morphology, by strict criteria, on the pre-washed IUI sample. Main outcomes Measures To determine the association of sperm morphology with CPR. Results Semen analysis reports, including Kruger strict criteria for morphology from the pre-washed IUI sample, were reviewed for 1,059 cycles, comprising 825 total treated couples.Of the total 1,059 cycles,15.1% resulted in clinical pregnancy. When categorized by strict morphology ≥4% (normal morphology), (3%-2%) [mild-moderate teratozoospermia (TZS)], and ≤1% (severe TZS), the CPR was 16%, 13%, and 10%, respectively (p value 0.30). Early spontaneous miscarriage rate was 4% and when stratified by morphology ≥4% (3%-2%), and ≤1%, was 3%, 1%, and 0%, respectively (p value 0.20).In couples with isolated TZS, the pregnancy rate was 16% in the normal morphology group, 14% in the mild-moderate group, and 8% in the severe group. (p value 0.30).In the multivariate logistic regression, sperm morphology, mild/moderate TZS vs normal forms (OR = 0.99, 95% CI [0.94-1.1]), severe TZS vs normal forms (OR = 0.98, 95% CI [0.0.83-1.1]), was not a predictor of CPR. The Pre-wash TMSC (OR = 1.0, 95% CI [0.996-1.00]) was also not predictive of CPR.The only predictive factor of CPR in IUI was the PWTMSC (OR = 1.03, 95%CI [1.00-1.06). Conclusions The morphology of the pre-washed sample on the day of IUI did not find a difference in CPR, neither in miscarriage rate following IUI, in couples with normal or abnormal sperm morphology, including severe TZS.Mild, moderate, or severe TZS in the semen sample should not exclude couples to attempt an IUI procedure.

Abstract
BACKGROUND The impact of sexual abstinence on sperm quality, particularly in pathological cases, is a subject of debate. We investigated the link between abstinence duration and semen quality in both normal and pathological samples. METHODS We analyzed semen samples from 4423 men undergoing fertility evaluation, comprising 1256 samples from healthy individuals and 3167 from those with conditions such as oligozoospermia, asthenozoospermia, teratozoospermia, or a combination of these factors, namely oligoasthenoteratozoospermia (OAT). Parameters including sperm concentration, the percentage of progressively motile spermatozoa, total motile sperm count, and the percentage of spermatozoa with normal morphology were assessed at various abstinence durations (each day, 0-2, 3-7, and >7 days). RESULTS Extended abstinence correlated with higher sperm concentration overall (p < 0.001), except in oligozoospermia. Longer abstinence reduced progressive motility in normal (p < 0.001) and teratozoospermic samples (p < 0.001). Shorter abstinence was linked to higher morphologically normal sperm in normal samples (p = 0.03), while longer abstinence did so in oligoasthenoteratozoospermic samples (p = 0.013). CONCLUSION The findings suggest that a prolonged abstinence time is linked to higher sperm concentration, while optimal sperm motility is observed after shorter abstinence periods. However, results regarding morphology remain inconclusive. Recommendations on abstinence duration should be tailored based on the specific parameter requiring the most significant improvement.

Abstract
Background The World Health Organization (WHO) recommends reporting sperm morphology in a standard semen analysis. However, the clinical utility and prognostic value of morphology is often debated. Methods We reviewed and summarized studies that assessed both the benefits and limitations of sperm morphology in the context of natural fertility, assisted reproductive technologies, and recurrent pregnancy loss. We additionally describe possible environmental and anatomical etiologies of teratozoospermia. Results Sperm morphology evaluation has continuously evolved since the release of the first WHO manual in 1980. Initially, several large studies reported significant inverse associations between fertility outcomes and teratozoospermia. Most recent studies, however, fail to show an association between sperm morphology and natural or assisted fertility outcomes. Conclusion Sperm morphology analysis may have limited diagnostic and prognostic value. Providers should be aware of these limitations when counseling or managing infertile patients.

Abstract
BACKGROUND Microdissection testicular sperm extraction (mTESE) is the mainstay of sperm retrieval in men with nonobstructive azoospermia (NOA). Some experts believe that a resting period of ≥6 months is required between procedures to ensure better sperm retrieval rates and fewer complications. However, no scientific studies have investigated how long patients should wait before arranging a second mTESE procedure. This retrospective study aimed to evaluate whether good success rates are still achieved when a repeat mTESE procedure is performed within 6 months. METHODS Total 146 patients with NOA who underwent mTESE twice from the same testis between May 2012 and September 2019 were retrospectively collected. These patients were categorized into three groups according to the time interval between the two mTESE surgeries, with 44, 60, and 42 patients undergoing a repeat mTESE after <3 months (group I), between 3 and 6 months (group II), and >6 months (group III) after the first procedure, respectively. RESULTS No significant differences were observed between groups in terms of patient characteristics and preoperative hormone profiles. Overall sperm retrieval rates did not differ among the three groups (93.2%, 90.0%, and 88.1% in groups I, II, and III, respectively [ p = 0.719]), nor did fertility outcomes, including rates of fertilization, biochemical pregnancy, clinical pregnancy, and cumulative live births. CONCLUSION Sperm retrieval rates for repeat mTESE procedures were consistently high, even when the second procedure was performed within 6 months of the first. Repeat mTESE within 6 months is not a limitation for patients with NOA, if required clinically.

Abstract
INTRODUCTION AND OBJECTIVE Sperm morphology has been used as a prognostic factor in in vitro fertilization, however, in intrauterine insemination (IUI) its predictive role is controversial. The aim of this study was to determine the impact of sperm morphology as isolated parameter of the spermiogram has on the probability of pregnancy in couples that are treated with IUI. MATERIAL AND METHODS Retrospective study of IUI cycles performed in the Reproductive Medicine Unit of Clínica Las Condes between January 2016 and December 2018. Logistic regression of the following variables: sperm morphology grouped in 0-1%, 2-3% and≥4%, total progressively motile sperm count inseminated, age of the woman and the man. RESULTS A total of 385 cases were included and clinical pregnancy was diagnosed in 85 of them. When separating into groups of sperm morphology<4% and≥4%, the pregnancy rate was 22% in both groups. The age of the woman was the only statistically significant factor in the logistic regression. The area under the ROC curve of sperm morphology as a predictor of pregnancy was 0.53. CONCLUSIONS Our study concludes that sperm morphology should not be considered as a single parameter when deciding whether or not a couple can be treated with IUI, eliminating isolated teratozoospermia as a direct indication for in vitro fertilization. It was not possible to determine a cut-off point for sperm morphology that serves as a predictor of pregnancy.

Abstract
BACKGROUND To determine the predictive values of sperm parameters pre- and post-processing by density gradient centrifugation for clinical pregnancy rates (CPRs) following artificial insemination by husband (AIH) in infertile Chinese couples. METHODS A total of 3,522 AIH cycles from 1,918 couples were retrospectively analyzed. The parameters were compared between the pregnant and non-pregnant groups and further between different etiological groups (Male-factor, Both-male-and-female-factor, and Other-factor). Multivariate logistic regression analysis was performed to create models for predicting the CPRs of each etiological group. RESULTS The overall CPR was 13.3%. There were significant improvements for most sperm parameters after DGC. Multivariate logistic regression analysis indicated that, in overall AIH cases, the top parameters significantly influencing the CPR of AIH were pre-STR (OR = 1.037; P = 0.048) and post-VSL (OR = 1.036; P = 0.011). In the Male-factor Group, the top influencing parameters were pre-VCL (OR = 2.096; P = 0.008), pre-LIN (OR = 1.930; P = 0.002) and post-VSL (OR = 1.316; P = 0.023). In the Both-factor Group, the top influencing parameters were pre-VCL (OR = 1.451; P = 0.008) and post-motility (OR = 1.218; P = 0.049). In the Other-factor Group, the top influencing parameters were pre-VAP (OR = 1.715; P = 0.024), pre-STR (OR = 1.20; P = 0.011) and post-VSL (OR = 1.04; P = 0.017). Moreover, receiver operating characteristic analysis showed that the logistic regression models of the Male- and Both-factor Groups had greater powers for prognostic classification than those of other groups. CONCLUSIONS This study demonstrated that some sperm parameters have a collinearity relationship in predicting the CPR following AIH. Moreover, the predictive capacity of a multivariate logistic regression model is better than those of individual parameters, especially for the Male- and Both-factor Groups. In these cases, pre-VCL is the common top influencing factor.

Abstract
The management of bacterial infections, especially trains of methicillin-resistant Staphylococcus aureus observe in health care settings, has markedly improved with the introduction of established drugs but using newer nano-based formulations. This study investigates the effects of vancomycin-linoleic acid nanoparticles on testicular tissue in an experimental animal model. Twenty-five adult male Sprague-Dawley rats maintained at the Animal House of the Biomedical Resources Unit were assigned to five groups namely E - solid lipid nanoparticles; F - vancomycin solid lipid nanoparticle; G - linoleic acid nanoparticle; H - vancomycin linoleic acid; and A - control. Perturbations in seminal fluid parameters showed a reduced sperm count in groups F & G which was statistically significant (p < .05) but motility and morphology were not significant when compared to controls (A). Reduced testosterone levels were found in groups E, F and H but were not statistically significant (p > .05). There was also increased luteinizing hormone (LH) and decreased in follicular stimulating hormone (FSH) levels was statistically significant (p < .05). Hypoplasia, tubular atrophy and shrinkage were observed in histologic sections of the treated groups with basement membrane thickening. Vancomycin solid lipid nanoparticle and its constituents SLN and LA disrupted testicular morphometry and the hormonal milieu sufficient to potentially induce altered reproductive function.

Abstract
INTRODUCTION Over the last decades, the use of intracytoplasmic sperm injection (ICSI) has increased, even among patients without male factor infertility. The increase has happened even though there is no evidence to support that ICSI results in higher live birth rates compared with conventional in vitro fertilisation (IVF) in cases with nonmale factor infertility. The lack of robust evidence on an advantage of using ICSI over conventional IVF in these patients is problematic since ICSI is more invasive, complex and requires additional resources, time and effort. Therefore, the primary objective of the IVF versus ICSI (INVICSI) study is to determine whether ICSI is superior to standard IVF in patients without severe male factor infertility. The primary outcome measure is first live birth from fresh and frozen-thawed transfers after one stimulated cycle. Secondary outcomes include fertilisation rate, ongoing pregnancy rate, birth weight and congenital anomalies. METHODS AND ANALYSIS This is a two-armed, multicentre, randomised, controlled trial. In total, 824 couples/women with infertility without severe male factor will be recruited and allocated randomly into two groups (IVF or ICSI) in a 1:1 ratio. Participants will be randomised in variable block sizes and stratified by trial site and age.

Evaluation of Prognostic Factors for Clinical Pregnancy Rate Following Artificial Insemination by Husband in the Chinese Population. Front Med (Lausanne) 2021; 8:638560. [PMID: 34041250 PMCID: PMC8141639 DOI: 10.3389/fmed.2021.638560] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 03/22/2021] [Indexed: 11/23/2022] Open
Abstract
Background: To determine the independent prognostic factors and develop a multivariate logistic regression model for predicting successful pregnancy following artificial insemination by husband (AIH) in infertile Chinese couples. Methods: A total of 3,015 AIH cycles with superovulation from 1,853 infertile Chinese couples were retrospectively analyzed. The clinical characteristics and sperm parameters were compared between the pregnant and non-pregnant groups. Multivariate logistic regression analysis was performed to remove the confounding factors and create an equation to predict the successful pregnancy. Receiver operating characteristic (ROC) curves were constructed for evaluating the abilities for prognostic classification of the independent predictors and the equation. Results: The overall pregnancy rate was 13.0%. The pregnancy rate of double intrauterine insemination (IUI) (18.9%) was significantly higher than that of single IUI (11.4%). The pregnancy rate of the stimulated cycle (14.4%) was significantly higher than that of the natural cycle (9.0%). The pregnancy rates of the age groups <40 years are ~3 times higher than that of the ≥40 years age group. Among sperm parameters, the influencing factors included straight-line velocity (VSL), sperm deformity index (SDI), and normal form rate (all P < 0.05). A multivariate logistic regression equation was created based on the above influencing factors. ROC analysis showed that the prognostic power of the equation is better than those of individual predictors. Conclusion: Cycle treatment options, single/double IUI, female age, sperm VSL, SDI, and normal form rate could predict successful pregnancy following AIH in China. The multivariate logistic regression equation exhibited a greater value for prognostic classification than single predictors.

Intracytoplasmic sperm injection versus conventional in-vitro fertilisation in couples with infertility in whom the male partner has normal total sperm count and motility: an open-label, randomised controlled trial. Lancet 2021; 397:1554-1563. [PMID: 33894833 DOI: 10.1016/s0140-6736(21)00535-3] [Citation(s) in RCA: 51] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 02/24/2021] [Accepted: 02/26/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND The use of intracytoplasmic sperm injection has increased substantially worldwide, primarily in couples with non-male factor infertility. However, there is a paucity of evidence from randomised trials supporting this approach compared with conventional in-vitro fertilisation (IVF). We aimed to investigate whether intracytoplasmic sperm injection would result in a higher livebirth rate compared with conventional IVF. METHODS This open-label, multicentre, randomised trial was done at two IVF centres in Ho Chi Minh City, Vietnam (IVFMD, My Duc Hospital and IVFAS, An Sinh Hospital). Eligible couples were aged at least 18 years and the male partner's sperm count and motility (progressive motility) were normal based on WHO 2010 criteria. Couples had to have undergone two or fewer previous conventional IVF or intracytoplasmic sperm injection attempts, have used an antagonist protocol for ovarian stimulation, and agree to have two or fewer embryos transferred. Couples were randomly assigned (1:1) to undergo either intracytoplasmic sperm injection or conventional IVF, using block randomisation with variable block size of 2, 4, or 8 and a telephone-based central randomisation method. The computer-generated randomisation list was prepared by an independent statistician who had no other involvement in the study. Embryologists and couples were not masked to study groups because of the type of interventions and differences in hospital fees, but clinicians performing embryo transfer were unaware of study group allocation. The primary outcome was livebirth after the first embryo transfer from the initiated cycle. Analyses were done on an intention-to-treat basis. The trial is registered with ClinicalTrials.gov, NCT03428919. FINDINGS Between March 16, 2018, and Aug 12, 2019, we randomly assigned 1064 couples to intracytoplasmic sperm injection (n=532) or conventional IVF (n=532). Livebirth after the first embryo transfer from the initiated cycle occurred in 184 (35%) of 532 couples randomly assigned to intracytoplasmic sperm injection and in 166 (31%) of 532 couples randomly assigned to conventional IVF (absolute difference 3·4%, 95% CI -2·4 to 9·2; risk ratio [RR] 1·11, 95% CI 0·93 to 1·32; p=0·27). 29 (5%) couples in the intracytoplasmic sperm injection group and 34 (6%) couples in the conventional IVF group had fertilisation failure (absolute difference -0·9%, -4·0 to 2·1, RR 0·85, 95% CI 0·53 to 1·38; p=0·60). INTERPRETATION In couples with infertility in whom the male partner has a normal total sperm count and motility, intracytoplasmic sperm injection did not improve the livebirth rate compared with conventional IVF. Our results challenge the value of the routine use of intracytoplasmic sperm injection in assisted reproduction techniques for this population. FUNDING My Duc Hospital and Merck Sharp and Dohme.

Effect of Sperm Morphology in Intrauterine Insemination: Analysis of 115 Cycles and Literature Review. Obstet Gynecol Surv 2021; 76:170-174.

Abstract
Importance The value of morphology as a sperm parameter remains uncertain. Many studies have addressed the importance of morphology to predict the success of intrauterine insemination (IUI), but with conflicting results. Objective The aims of this study were to review the current literature, to query our own clinical experience via a retrospective, descriptive study, and to determine whether the diagnosis of isolated teratozoospermia influences pregnancy rate after IUI. Results We identified a large number of studies addressing this question. All were retrospective and most used different criteria to assess sperm morphology. Further complicating matters, the cutoff for normal morphology decreased from 15% to 4%. In our patient population, we found 12 cases of isolated teratozoospermia (10.43%). Only one of these produced an ongoing pregnancy and live birth. In all other cases, alteration of other sperm parameters coexisted (89.57%). These cycles produced a pregnancy rate of 13%, a nonsignficant difference. Pregnancy rates also were analyzed according to the percentage of normal morphology: 35.71% for less than 4%, 50% for 5% to 9%, and 14.29% for 10% to 14%. These rates did not differ significantly. Conclusions and Relevance No consistent effect of sperm morphology on pregnancy rate was found in either the published literature or our own clinical experience. Larger and prospective studies are needed to identify any subtle effects of morphology on IUI outcomes that might exist.

Abstract
Background: Intrauterine insemination (IUI) is a widely utilized method for treating the infertile couples. The aim of the present study was to determine the pregnancy and abortion rates after IUI and to examine the relationship of sperm parameters with these rates. Methods: This retrospective study was performed on 911 infertile couples undergoing IUI treatment in Shahid Akbarabadi IVF Centre from May 2017 to May 2019. To evaluate the correlation of sperm parameters with the clinical pregnancy and abortion rates, odds ratio (OR) with 95% confidence intervals (CI) was calculated. Results: In this study, the pregnancy rate following IUI was 15.7% (143/911), and among women who achieved pregnancy, the abortion rate was 42.0% (60/143). According to the multiple logistic regression analysis, none of the sperm parameters was associated with the pregnancy rate. Couples with either male or female factor infertility etiologies were more likely to get pregnant than those with unexplained infertility. Regarding the abortion rate, multiple logistic regression analysis revealed that normal sperm count was related to a lower abortion rate (adjusted OR=0.25, 95% CI=0.07–0.91). Conclusion: The present study did not reveal a significant relationship between none of the sperm parameters and pregnancy rate after IUI treatment. However, among women who got pregnant, continuation of the pregnancy was associated with the normal sperm count. Furthermore, analysis of all semen parameters together in comparison to one parameter alone might be more accurate to predict pregnancy or abortion. Further prospective cohort studies with a large number of couples are required.

Abstract
OBJECTIVE The objective of this retrospective cohort study was to explore the optimal range of the total progressive motile sperm count (TPMSC) for live birth in couples with varying infertility diagnosis undergoing intrauterine insemination (IUI) in a university-affiliated teaching hospital. METHODS A total of 2647 couples and 5171 IUI cycles were included between January 2015 and December 2018. Of those, 1542 cycles were performed due to unexplained infertility, 1228 cycles due to anovulation, 1120 cycles due to mild male factor infertility and 122 cycles due to mild endometriosis. The primary outcome measure was live birth rate (LBR). The secondary outcome measure was clinical pregnancy rate (CPR). RESULTS The CPR and LBR were highest in patients with a diagnosis of anovulation compared with the other three groups of patients. The CPR and LBR in patients with unexplained, mild male factor and mild endometriosis were comparable. For the patients with mild male factor infertility, the CPR with prewash TPMSC of >75.0 M and postwash TPMSC of 65.10 M was above 10%, statistically significantly higher than other quartiles of TPMSC (p<0.05). The LBR with postwash TPMSC of >65.10 M was statistically significantly higher than other groups (p<0.05). However, in patients with unexplained infertility, the CPR and LBR were not statistically different in quartiles of TPMSC, being less than 10%. Overall, there was only one clinical pregnancy and no live birth in patients >40 years of age. CONCLUSIONS In conclusion, the infertility diagnosis plays a significant role for the patient undergoing IUI. Thus, the anovulatory patients benefitted most from IUI, irrespective of TPMSC. For patients with unexplained infertility, TPMSC does not affect the success rate of IUI. Overall,female patients more than 40 years old should not be referred to IUI.

Abstract
Objective To determine the effect of sperm morphology from the specific sample used for intrauterine insemination (IUI) on clinical pregnancy rates (CPR). Design Prospective cohort study. Setting Academic fertility clinic. Patients Couples undergoing IUI July 2016-January 2017. Interventions Morphology slides were prepared from the semen sample produced for IUI. Main Outcome Measures CPR was measured by detection of cardiac activity. Multiple logistic regression modeling was performed to determine the association of sperm morphology with CPR, controlling for age, antimüllerian hormone level, and post-wash total motile sperm count. Results Semen analyses, including Kruger strict criteria for morphology from the actual sample inseminated, were reviewed for 155 couples, comprising 234 total treatment cycles. The percent normal morphology significantly differed between the preliminary semen analysis and the IUI sample (-2.0% +3.7% (95% CI -2.55, -1.53). Of the total 234 treatment cycles, 8.6% resulted in clinical pregnancy. When categorized by strict morphology >4%, <4%, and <1%, the CPR was 6.6%, 9.8%, and 10.9%, respectively. In couples with otherwise normal semen parameters (isolated teratospermia), CPR by >4%, <4%, and <1% normal forms was 7.2%, 9.8%, and 11.1%, respectively. There was no significant association between the percent normal morphology and CPR in multivariate analysis. Conclusions This study evaluating the morphology of the actual inseminated sample did not find differences in CPR following IUI among couples with normal and abnormal sperm morphology, including severe teratospermia. Abnormal sperm morphology should not exclude couples from attempting IUI.

Abstract
RESEARCH QUESTION To date, most studies have investigated the minimum number of spermatozoa available for intrauterine insemination (IUI), with no data on the maximum number of motile spermatozoa inseminated (NMSI) having been published. This study aimed to determine whether an upper cut-off for the NMSI during IUI exists above which the live birth rate (LBR) is negatively affected. DESIGN Retrospective analysis of autologous IUI cycles performed between January 2010 and July 2018 in women <43 years old with a NMSI >1 million. The main outcome was the LBR per IUI cycle as a function of the NMSI. RESULTS A total of 2592 IUI cycles performed in 1017 couples were included. The LBR increased with NMSI up to 30 million without any upper threshold (AUC = 0.5441). The LBR per IUI cycle were 14.5%, 17.9% and 22.7% for NMSI of >1 to ≤10, >10 to ≤20 and >20 to ≤30 million, respectively (P = 0.003). By univariate analysis, the NMSI, female age, number of mature follicles and oestradiol concentrations on day of ovulation triggering, cycle number and infertility aetiology influenced the LBR. Multivariate analysis showed that the LBR was 1.49 and 1.78 times higher when IUI was performed with a NMSI >10 to ≤20 million (odds ratio [OR] 1.49; 95% confidence interval [CI] 1.10-2.02]) and >20 to ≤30 million (OR 1.78; 95% CI 1.08-2.94), respectively, compared with IUI with a NMSI >1 to ≤10 million. CONCLUSIONS The LBR after IUI can be optimized by inseminating a maximum of motile spermatozoa up to 30 million. Thus, in this specific cohort, IUI preparations should not be diluted when more than 10 million motile spermatozoa are obtained.

Abstract
PURPOSE OF REVIEW The classification of morphologically normal sperm has been progressively redefined. Concurrently, our understanding of the significance of sperm morphology in relation to male factor infertility has evolved. In this review, we will discuss the evolution of sperm morphology assessment and factors that contribute to its measurement variability. We will examine the impact of sperm morphology on natural pregnancy, IUI, IVF, and ICSI outcomes. RECENT FINDINGS There is a lack of consensus on sperm morphology classification, technique, and inter-observer grading variability. Current evidence suggests sperm morphology has low predictive value for pregnancy success, for both natural and assisted reproduction. Additionally, the threshold for what is considered an adequate percentage of morphologically normal sperm has changed over time. These variables have called into question the relevance of this variable in predicting fertility outcomes. Our understanding of the impact of sperm morphology on reproductive outcomes continues to evolve and seems to play less of a role than initially thought.

Effect of insemination timing on pregnancy outcome in association with female age, sperm motility, sperm morphology and sperm concentration in intrauterine insemination. J Obstet Gynaecol Res 2018; 44:1100-1106. [PMID: 29673000 DOI: 10.1111/jog.13625] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2017] [Accepted: 02/05/2018] [Indexed: 12/01/2022]
Abstract
AIM We investigated the effect of insemination timing on pregnancy outcomes in intrauterine insemination (IUI) cycles. METHODS This is a retrospective study of 411 IUI cycles performed with a diagnosis of unexplained infertility and male factor infertility. The cycles were divided according to the interval between insemination and ovulation: ≤36 h, 36-37 h, 37-38 h and >38 h. The overall pregnancy rate, chemical pregnancy rate and clinical pregnancy rate were compared. We also analyzed the association between pregnancy outcomes and clinical characteristics, including age, duration of infertility, sperm concentration, body mass index (BMI), anti-Müllerian hormone (AMH) and number of mature follicles at ovulation. RESULTS There were no differences regarding age, duration of infertility, BMI, AMH, sperm concentration and number of mature follicles between different IUI timing groups. Sperm morphology was significantly lower in ≤36 h group (5.3 ± 1.4) compared to 36-37 h, 37-38 h and >38 h (6.3 ± 2.5 vs 6.5 ± 2.7 vs 6.5 ± 3.5, P = 0.004) groups. The ≤36 h group showed lowest total pregnancy rate (5.0%) compared to other IUI timings (21.8% vs 24.8% vs 20.0%, P = 0.05). Multivariate analysis showed that sperm morphology was associated with pregnancy in 36-37 h (odd ratio 1.42, 95% confidence interval 1.03-1.95, P = 0.02). CONCLUSION Insemination at least 36 h after ovulation is associated with increased pregnancy rate compared to IUIs performed ≤36 h following ovulation.

Abstract
PURPOSE Men with abnormal sperm morphology are often counseled that natural conception and intrauterine insemination are ineffective, and in vitro fertilization is the only option. Our objective was to determine the effect of sperm morphology on the pregnancy success of intrauterine insemination. MATERIALS AND METHODS We systematically searched for studies published prior to January 2017 that 1) reported ultrasound verified clinical pregnancies per intrauterine insemination cycle, 2) assessed sperm morphology using the Kruger strict criteria and 3) described morphology at the greater than 4% and 4% or less and/or the 1% or greater and less than 1% thresholds. In all studies mean female age was between 25 and 40 years and mean total motile sperm count was greater than 10 million. Estimates were pooled using random effects meta-analysis. RESULTS Data were extracted from 20 observational studies involving a total of 41,018 cycles. When comparing men at the greater than 4% and 4% or less thresholds, the rate of ultrasound verified pregnancy per intrauterine insemination cycle was not statistically or clinically different (14.2% vs 12.1%, p = 0.06) and the risk difference was 3.0% (95% CI 1.4-4.6), indicating 3.0 additional pregnancies per 100 intrauterine insemination cycles. When comparing men at the 1% or greater and the less than 1% thresholds, there were no statistical or clinical differences in the rate of ultrasound verified pregnancy per cycle of intrauterine insemination (14.0% vs 13.9%, p = 0.97) or in the risk difference (1.6%, 95% CI -4.5-7.6). CONCLUSIONS There appears to be no clinical difference in intrauterine insemination pregnancy success among men with normal and abnormal sperm morphology when accounting for total motile sperm count and female age. Abnormal sperm morphology alone should not exclude couples from attempting intrauterine insemination.

Abstract
The evaluation of strict morphology for predicting successful pregnancy has been controversial, nevertheless remains an essential component of semen analysis. Patients with teratozoospermia (abnormal strict morphology) have traditionally been counseled to undergo assisted reproduction. However, recent studies suggest that patients with abnormal sperm morphology alone should not be precluded from attempting natural conception before undergoing assisted reproduction. The goal of this review is to provide an update on the evaluation of sperm morphology for prognosis in assisted reproductive techniques such as intrauterine insemination and in vitro fertilization with or without intracytoplasmic sperm injection. Additionally, we propose a logical approach to the evaluation of a patient with teratozoospermia seeking fertility treatment.

Abstract
This study sought to investigate whether isolated abnormal strict morphology (<5% normal forms) and very low strict morphology (0-1% normal forms) affects pregnancy rates in intrauterine insemination (IUI). This was a retrospective study performed at an Academic Medical Center/Reproductive Medicine Center. Four hundred and eight couples were included for 856 IUI cycles. 70 IUI cycles were performed in couples with abnormal strict morphology and otherwise normal semen parameters. Outcomes were measured as clinical pregnancy rate per IUI cycle as documented by fetal heart activity on maternal ultrasound. Clinical pregnancy rate did not significantly differ between the group with abnormal strict morphology [11/70 (15.7%)] and the normal morphology group [39/281 (13.9%)]. Additionally, there was no significant difference between the pregnancy rate in the abnormal morphology group compared to that of our overall institutional IUI pregnancy rate [145/856 (16.9%)]. Furthermore, there was no significant difference between pregnancy rate in the very low morphology group [3/14 (21.4%)] compared to those with normal morphology or the overall IUI pregnancy rate. Patients with isolated abnormal strict morphology have clinical pregnancy rates similar to those with normal morphology for IUI. Even in those with very low normal forms, consideration of IUI for assisted reproduction should not be excluded.

Abstract
OBJECTIVE To evaluate the effect of microsurgical varicocelectomy on sperm morphology in subfertile men with isolated teratozoospermia and a clinically palpable varicocele. MATERIALS AND METHODS A retrospective review was performed of men with isolated teratozoospermia who had undergone microsurgical varicocelectomy. Semen analyses following varicocelectomy were performed at 2- to 3-month intervals. Responders to the varicocelectomy were defined as those who fulfilled the following criteria in semen analysis: (1) an improvement in percentage of normal forms to ≥4% and (2) normal results for all other semen parameters. RESULTS A total of 80 patients underwent unilateral varicocelectomy (n = 49) or bilateral varicocelectomy (n = 31) (mean age of 36 ± 0.4 years, range 24-44). After a mean postoperative follow-up period of 6.8 months, the mean percentage of normal sperm forms increased from 0.9% to 3.5% (P < .001), and the mean sperm motility improved from 50.5% to 56.6% (P = .004). The number of responders to the surgery was 16 (20%), and their mean percentage of normal forms increased from 1.3% to 9.1%. The mean preoperative and postoperative semen volume and sperm concentration were not different (P > .05). No differences were observed in age, current smoking status, body mass index, or grade of varicocele between responders and nonresponders. CONCLUSION Varicocelectomy might be an option for treating subfertile patients with isolated teratozoospermia and a clinically apparent varicocele. However, patients should be advised that the surgery helps in limited patients only because more patients did not benefit from the surgery.

Total motile sperm count: a better indicator for the severity of male factor infertility than the WHO sperm classification system. Hum Reprod 2015; 30:1110-21. [PMID: 25788568 DOI: 10.1093/humrep/dev058] [Citation(s) in RCA: 127] [Impact Index Per Article: 14.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2014] [Accepted: 02/20/2015] [Indexed: 11/14/2022] Open
Abstract
STUDY QUESTION Does the prewash total motile sperm count (TMSC) have a better predictive value for spontaneous ongoing pregnancy (SOP) than the World Health Organization (WHO) classification system? SUMMARY ANSWER The prewash TMSC shows a better correlation with the spontaneous ongoing pregnancy rate (SOPR) than the WHO 2010 classification system. WHAT IS KNOWN ALREADY According to the WHO classification system, an abnormal semen analysis can be diagnosed as oligozoospermia, astenozoospermia, teratozoospermia or combinations of these and azoospermia. This classification is based on the fifth percentile cut-off values of a cohort of 1953 men with proven fertility. Although this classification suggests accuracy, the relevance for the prognosis of an infertile couple and the choice of treatment is questionable. The TMSC is obtained by multiplying the sample volume by the density and the percentage of A and B motility spermatozoa. STUDY DESIGN, SIZE, DURATION We analyzed data from a longitudinal cohort study among unselected infertile couples who were referred to three Dutch hospitals between January 2002 and December 2006. Of the total cohort of 2476 infertile couples, only the couples with either male infertility as a single diagnosis or unexplained infertility were included (n = 1177) with a follow-up period of 3 years. PARTICIPANTS/MATERIALS, SETTING, METHODS In all couples a semen analysis was performed. Based on the best semen analysis if more tests were performed, couples were grouped according to the WHO classification system and the TMSC range, as described in the Dutch national guidelines for male infertility. The primary outcome measure was the SOPR, which occurred before, during or after treatments, including expectant management, intrauterine insemination, in vitro fertilization or intracytoplasmic sperm injection. After adjustment for the confounding factors (female and male age, duration and type of infertility and result of the postcoital test) the odd ratios (ORs) for risk of SOP for each WHO and TMSC group were calculated. The couples with unexplained infertility were used as reference. MAIN RESULTS AND THE ROLE OF CHANCE A total of 514 couples did and 663 couples did not achieve a SOP. All WHO groups have a lower SOPR compared with the unexplained group (ORs varying from 0.136 to 0.397). Comparing the couples within the abnormal WHO groups, there are no significant differences in SOPR, except when oligoasthenoteratozoospermia is compared with asthenozoospermia [OR 0.501 (95% CI 0.311-0.809)] and teratozoospermia [OR 0.499 (95% CI: 0.252-0.988)], and oligoasthenozoospermia is compared with asthenozoospermia [OR 0.572 (95% CI: 0.373-0.877)]. All TMSC groups have a significantly lower SOPR compared with the unexplained group (ORs varying from 0.171 to 0.461). Couples with a TMSC of <1 × 10(6) and 1-5 × 10(6) have significantly lower SOPR compared with couples with a TMSC of 5-10 × 10(6) [respectively, OR 0.371 (95% CI: 0.215-0.64) and OR 0.505 (95% CI: 0.307-0.832)]. LIMITATIONS, REASON FOR CAUTION To include all SOPs during the follow-up period of 3 years, couples were not censured at the start of treatment. WIDER IMPLICATIONS OF THE FINDINGS Roughly, three prognostic groups can be discerned: couples with a TMSC <5, couples with a TMSC between 5 and 20 and couples with a TMSC of more than 20 × 10(6) spermatozoa. We suggest using TMSC as the method of choice to express severity of male infertility. STUDY FUNDING/COMPETING INTERESTS None.
