Can anti-Mullerian hormone (AMH) predict the outcome of intrauterine insemination with controlled ovarian stimulation?

Anti-Müllerian hormone for screening, diagnosis, evaluation, and prediction: A systematic review and expert opinions

AIM

To present evidence-based recommendations for anti-Müllerian hormone (AMH) measurement as an ovarian reserve test.

METHODS

A systematic literature search for the clinical utility of AMH was conducted in PubMed from its inception to August 2022 to identify studies, including meta-analyses, reviews, randomized controlled trials, and clinical trials, followed by an additional systematic search using keywords. Based on this evidence, an expert panel developed clinical questions (CQs).

RESULTS

A total of 1895 studies were identified and 95 articles were included to establish expert opinions subdivided into general population, infertility treatment, primary ovarian insufficiency, polycystic ovary syndrome, surgery, and oncofertility. We developed 13 CQs and 1 future research question with levels of evidence and recommendations.

CONCLUSION

The findings of the current systematic review covered the clinical utility of AMH including its screening, diagnosis, evaluation, and prediction. Although some clinical implications of AMH remain debatable, these expert opinions may help promote a better understanding of AMH and establish its clinical significance.

Anti-Müllerian Hormone: A Predictor of Successful Intrauterine Insemination

INTRODUCTION

The anti-Müllerian hormone (AMH) produced by the granulosa cells of ovarian follicles has been shown to correlate with ovarian reserve and is often measured for fertility therapies. In this study, we evaluated the relationship between serum AMH values and the clinical pregnancy (CP) rates of female partners with unexplained infertility undergoing intrauterine insemination utilizing varying ovarian simulation protocols.

METHODS

This is a retrospective cohort study conducted among couples who underwent intrauterine insemination therapy over a period of four years at Charleston Area Medical Center, a tertiary care medical center in West Virginia, USA. Logistic regression was used to determine the best predictor of CP.

RESULTS

A total of 509 intrauterine inseminations resulting in 81 (15.9%) Cps were analyzed. The cycles with a CP had higher mean AMH values (3.7+3.5 vs. 2.2+2.1; p<0.001). The majority of patients were nulliparous (77.0%) with a mean age of 33.6+5.0 years. After including only patients with unexplained infertility (the predominate infertility diagnosis; n=255 (50.1% of the cycles)) and stimulation cycles >10, the final sample size for the analysis was 245/509=48.1%. Following a receiver operating characteristic (ROC) curve analysis, the optimal AMH cut-off point was 2.1 ng/mL with an area under the curve (AUC) equal to 0.61 and 95% confidence intervals (CIs) of 0.55- 0.67 (p=0.002). The CP rate was significantly higher with the AMH >2.1 ng/mL (20.0%) compared to <2.1 ng/mL (10.0%; p=0.041). With Clomid/human gonadotropins/human chorionic gonadotropin (hCG) trigger treatment, the CP rate quadrupled (odds ratio (OR): 4.6; 95% CI: 2.1-9.7; p<0.001).

CONCLUSION

This study indicates that higher AMH levels and a more aggressive ovarian stimulation protocol for intrauterine insemination therapy (IUI) have a better probability of resulting in CP.

Using serum anti-Müllerian hormone levels to predict the chance of live birth after spontaneous or assisted conception: a systematic review and meta-analysis

STUDY QUESTION

Is serum anti-Müllerian hormone (AMH) level predictive of cumulative live birth (CLB) rate after ART or in women trying to conceive naturally?

SUMMARY ANSWER

Serum AMH level is linked to CLB after IVF/ICSI but data are lacking after IUI or in women trying to conceive without ART.

WHAT IS KNOWN ALREADY

Serum AMH level is a marker of ovarian reserve and a good predictor of ovarian response after controlled ovarian stimulation. It is unclear whether AMH measurement can predict CLB in spontaneous or assisted conception.

STUDY DESIGN, SIZE, DURATION

A systematic review and meta-analysis was undertaken to assess whether serum AMH level may predict chances of CLB in infertile women undergoing IVF/ICSI or IUI and/or chances of live birth in women having conceived naturally.

PARTICIPANTS/MATERIALS, SETTING, METHODS

A systematic review and meta-analysis was performed using the following keywords: 'AMH', 'anti-mullerian hormone', 'live-birth', 'cumulative live birth'. Searches were conducted from January 2004 to April 2021 on PubMed and Embase. Two independent reviewers carried out study selection, quality, and risk of bias assessment as well as data extraction. Odds ratios were estimated using a random-effect model. Pre-specified sensitivity analyses and subgroup analyses were performed. The primary outcome was CLB.

MAIN RESULTS AND THE ROLE OF CHANCE

A total of 32 studies were included in the meta-analysis. Overall, 27 articles were included in the meta-analysis of the relation between AMH and CLB or AMH and LB after IVF/ICSI. A non-linear positive relation was found in both cases. A polynomial fraction was the best model to describe it but no discriminant AMH threshold was shown, especially no serum AMH level threshold below which live birth could not be achieved after IVF/ICSI. After IVF-ICSI, only four studies reported CLB rate according to AMH level. No statistically significant differences in mean serum AMH levels were shown between patients with and without CLB, but with a high heterogeneity. After exclusion of two studies with high risks of bias, there was no more heterogeneity [I2 = 0%] and the mean AMH level was statistically significantly higher in women with CLB. There were not enough articles/data to assess the ability of AMH to predict CLB rate or find an AMH threshold after IUI or in women without history of infertility trying to conceive without ART.

LIMITATIONS, REASONS FOR CAUTION

The systematic review and meta-analysis had some limitations owing to the limits and bias of the studies included. In the present meta-analysis, heterogeneity may have been caused by different baseline characteristics in study participants, different stimulating protocols for ART, different serum AMH level thresholds used and the use of various assays for serum AMH. This could explain, in part, the absence of a discriminating AMH threshold found in this analysis.

WIDER IMPLICATIONS OF THE FINDINGS

Serum AMH level is linked to CLB rate after IVF/ICSI but no discriminating threshold can be established, therefore low serum AMH level should not be used as the sole criterion for rejecting IVF treatment, especially in young patients. Data are lacking concerning its predictive value after IUI or in women trying to conceive without ART. Our findings may be helpful to counsel candidate couples to IVF-ICSI.

Predicting success of intrauterine insemination using a clinically based scoring system

Purpose

To develop a predictive score for the success of intrauterine insemination (IUI) based on clinical parameters.

Methods

We performed a retrospective cohort study evaluating the homologous IUI cycles performed at a single university-based reproductive medical center between 2009 and 2017. The primary outcome measure was pregnancy, defined as positive serum human chorionic gonadotropin (hCG) 12–14 days after IUI. Predictive factors for pregnancy after IUI were identified, and a predictive score was developed using a multivariable continuation ratio model.

Results

Overall, 1437 IUI cycles in 758 couples were evaluated. We found a per cycle pregnancy rate of 10.9% and a cumulative pregnancy rate of 19.4%. In a multivariable analysis, the probability of pregnancy was negatively associated with female age ≥ 35 years (OR 0.63, 95% CI 0.41–0.97, p = 0.034), endometriosis, unilateral tubal factor, or anatomical alteration (OR 0.54, 95% CI 0.33–0.89, p = 0.016), anti-Mullerian hormone (AMH) < 1 ng/ml (OR 0.50, 95% CI 0.29–0.87, p = 0.014), and total progressive motile sperm count (TPMSC) < 5 mil (OR 0.47, 95% CI 0.19–0.72, p = 0.004). We developed a predictive clinical score ranging from 0 to 5. Following 3 cycles, couples in our cohort with a score of 5 had a cumulative probability of achieving pregnancy of nearly 45%. In contrast, couples with a score of 0 had a cumulative probability of only 5%.

Conclusion

IUI success rates vary widely depending on couples’ characteristics. A simple to use score could be used to estimate a couple’s chance of achieving pregnancy via IUI, facilitating individualized counseling and decision-making.

Discordance between day-3 follicle stimulating hormone & anti-Müllerian hormone is predictive of clinical pregnancy during fertility treatment

OBJECTIVE

To evaluate the role of discordant Day-3 follicle stimulating hormone (FSH) & anti-Müllerian hormone (AMH) levels in predicting pregnancy outcome after controlled ovarian stimulation (COS) followed by intrauterine insemination or timed intercourse.

METHODS

Retrospective study of 745 couples with regular menstrual cycles, at least one patent fallopian tube, and normal semen analysis that underwent infertility treatment between June 2013 and March 2017. Women with documented serum AMH and FSH levels (<10 (mIU/ml were considered normal), and undergo COS were studied. Clinical pregnancy rate is the cumulative pregnancy obtained after maximum of three cycles of COS with or without IUI.

RESULTS

As expected, patients with normal concordant AMH/FSH achieved a significantly (p < .01) higher pregnancy than all other groups. 22.4% of those with discordant normal AMH/abnormal FSH became pregnant while only 10.8% of those with discordant abnormal AMH/normal FSH levels did. 11.7% of patients with abnormal concordant values achieved pregnancy. Patients with discordant abnormal AMH/normal FSH were not statistically different (p = .084) from abnormal concordance AMH/FSH but significantly (p < .01) lower than normal concordant AMH/FSH. However, patients with discordant normal AMH/abnormal FSH were statistically different from both concordant normal and concordant abnormal AMH/FSH values (p < .04).

CONCLUSIONS

This study showed that both discordant abnormal Day-3 FSH and/or abnormal AMH serum levels, as well as concordant abnormal FSH and AMH values, were predictive of lower clinical pregnancy rates after COS. However, abnormal FSH with a normal AMH does not have as poor a prognosis as the presence of an abnormal AMH.

Pretreatment antimüllerian hormone levels and outcomes of ovarian stimulation with gonadotropins/intrauterine insemination cycles

OBJECTIVE

To evaluate the association, if any, between serum antimüllerian hormone (AMH) levels and probability of clinical pregnancy and spontaneous abortion (SAB) in the infertility setting.

DESIGN

Retrospective cohort study.

SETTING

Academic fertility center.

PATIENT(S)

A total of 1,861 gonadotropin stimulation/intrauterine insemination cycles stratified by AMH levels into 3 groups: Low, <25th percentile (<0.7 ng/mL); Middle, ≥25th and <75th percentile (0.7-4.4 ng/mL); and High, ≥75th percentile (≥4.5 ng/mL).

INTERVENTION(S)

Intrauterine insemination after stimulation with gonadotropins.

MAIN OUTCOME MEASURE(S)

Cumulative probability of clinical pregnancy over a maximum of 3 and/or 6 cycles and SAB incidence risk rate (IRR). The Kaplan-Meier failure function (log rank test), Cox proportional hazards models, and multilevel mixed-effects Poisson regression models were performed to compare outcomes among the AMH groups.

RESULT(S)

Overall, in both unadjusted and adjusted models, the probability of achieving a clinical pregnancy was higher in the Middle and High AMH groups compared with that in the Low AMH group, both over 3 (hazard ratios [95% confidence interval], 1.55 [1.05-2.29] and 1.85 [1.22-2.81], respectively) and 6 (1.71 [1.17-2.48] and 2.12 [1.42-3.16], respectively) cycles. In the unadjusted models, the SAB IRR was higher among the Low AMH group (IRR [95% confidence interval], 2.17 (1.11-4.24]), with the relationship persisting after adjusting for age (1.83 [0.93-3.60]). When the SAB IRR were calculated separately for the subpopulations with and without polycystic ovary syndrome, a similar relationship was noted among the latter in the unadjusted (1.94 [0.97-3.88]) and adjusted (1.74 [0.86-3.49]) analyses.

CONCLUSION(S)

In women undergoing gonadotropin stimulation/intrauterine insemination, AMH appears to affect the probability of achieving a clinical pregnancy. A possible negative impact, independent of age, on the risk of SAB was also suggested.

Ultrasound guidance versus the classical method for intrauterine insemination in oral medication-stimulated cycles: A randomized, single-blind, controlled trial

OBJECTIVE

This study was conducted to compare the pregnancy rates of ultrasound-guided intrauterine insemination (UG-IUI) and classical intrauterine insemination (C-IUI) cycles.

STUDY DESIGN

A total of 320 infertile women were enrolled and randomized into an UG-IUI group, and a C-IUI group. All participants received an oral medication for ovarian stimulation. With both groups, the IUIs were scheduled and performed by doctors in their residency and fellowship training, under supervision. The duration and difficulty of the procedures were assessed. A pregnancy test was offered 3 weeks later if the participants did not have menstruation.

RESULTS

The demographic and other baseline characteristics of the groups (baseline hormone levels, cervical length, uterine position, endometrial thickness, and expertise of the providers) were comparable. The pregnancy rates were similar, with 6.9 % and 6.3 % for the UG-IUI and C-IUI groups, respectively. In the UG-IUI group, the pregnancy rate of the multigravida women was three times higher than that of the nulligravida women (15.4 % vs. 5.0 %; p = 0.13). Although the duration of the procedure was shorter for the UG-IUI group (p < 0.05), the level of difficulty was similar for the two groups.

CONCLUSIONS

For oral-medication stimulated cycles, UG-IUI did not increase the pregnancy rate more than with C-IUI. However, the pregnancy rate tended to increase with UG-IUI for multigravida women.

Clinical Application of AMH Measurement in Assisted Reproduction

Anti-Müllerian hormone reflects the continuum of the functional ovarian reserve, and as such can predict ovarian response to gonadotropin stimulation and be used to individualize treatment pathways to improve efficacy and safety. However, consistent with other biomarkers and age-based prediction models it has limited ability to predict live birth and should not be used to refuse treatment, but rather to inform counselling and shared decision making. The use of absolute clinical thresholds to stratify patient phenotypes, assess discordance and individualize treatment protocols in non-validated algorithms combined with the lack of standardization of assays may result in inappropriate classification and sub-optimal clinical decision making. We propose that holistic baseline phenotyping, incorporating antral follicle count and other patient characteristics is critical. Treatment decisions driven by validated algorithms that use ovarian reserve biomarkers as continuous measures, reducing the risk of misclassification, are likely to improve overall outcomes for our patients.

Is ovarian reserve associated with body mass index and obesity in reproductive aged women? A meta-analysis

OBJECTIVE

The associations of body mass index (BMI) and obesity with ovarian reserve are controversial. This systematic review and meta-analysis was conducted to investigate the associations in reproductive-aged women.

METHODS

PubMed and Scopus were searched up to December, 2016. Original studies on the association of BMI with ovarian reserve markers, anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), inhibin β, and antral follicle count (AFC), either according to BMI categories or a continuous variable, were selected. Analyses were stratified into three groups based on polycystic ovary syndrome (PCOS) and fertility status of women.

RESULTS

Of 4,055 records identified, 45 studies were eligible for inclusion. Comparing the obese with nonobese, the pooled mean differences (MDs) and 95% confidence intervals (CIs) were -1.08 (95% CIs -1.52, -0.63) ng/mL for AMH, -0.22 (95% CIs -0.39, -0.06) mIU/mL for FSH, -0.09 (95% CIs -0.60, 0.42) for AFC, and -21.06 (95% CIs -41.18, -0.85) pg/mL for inhibin β in overall populations. The MDs were significant for AMH in fertile non-PCOS and PCOS women, and for FSH only in PCOS women. Fisher's Z showed significant correlations of BMI with AMH in the overall populations (-0.15 [95% CIs -0.20, -0.11]) and in all subgroups, and with FSH in the fertile non-PCOS women (-0.16 [95% CIs -0.28, -0.04]).

CONCLUSION

Ovarian reserve markers of AMH and FSH are significantly lower in obese than in nonobese women, and BMI is negatively correlated with AMH in all study populations, and with FSH in fertile non-PCOS subgroups. PCOS and fertility status do not appear to affect the associations.

Intrauterine insemination as a primary viable option to infertile couples: evaluation of patients in a private center

OBJECTIVE

This study aimed to identify which parameters positively affect the clinical pregnancy rates of IUI cycles and find which couples should opt for IUI.

METHODS

This retrospective observational study included 261 patients submitted to 381 IUI cycles with fresh or cryopreserved partner semen (IU-H) from January 2012 to February 2017 in a private center in Curitiba-PR, Brazil.

RESULTS

Idiopathic infertility was the most frequent finding (35.9%). Patients younger than 40 years accounted for 87.9% of the IUI cycles (n=335) and 16.1% of the clinical pregnancies (n=54). The pregnancy rate was three times higher in patients with an endometrium thickness ≥8 mm compared to patients with endometrium thickness <8mm. Sperm motility >55% was linked to higher pregnancy rates (p=0.002). Concerning gonadotropins, 159 (48.4%) took rFSH, 127 (38.7%) hMG, and 42 (12.8%) uFSH, with pregnancy rates of 21.3%, 10.4% and 10.5%, respectively.

CONCLUSION

Patients under 40 years of age with endometrium thickness ≥8 mm, sperm motility >55%, and on rFSH had significantly higher pregnancy rates (p<0.05).

Age-specific anti-Mullerian hormone (AMH) levels poorly affects cumulative live birth rate after intra-uterine insemination

Objective

To evaluate the impact of age-specific anti-Mullerian (AMH) levels on the cumulative live birth rate after 4 intra uterine inseminations (IUI).

Study Design

The retrospective study study involved 509 couples who underwent their first IUI between January 2011 and July 2017 in the Toulouse University Hospital. All IUI were performed after an ovarian stimulation combining recombinant FSH and GnRH antagonist. The main measure outcome was the cumulative live birth rate (LBR) defined as the number of deliveries with at least one live birth resulting from a maximum of 4 IUI attempts.

Results

When compared to normal or high levels, low age-specific AMH (<25th of the AMH in each age group) was associated to a non-significant lower live birth rate (31%, 38% and 42% respectively for low, normal and high age-specific groups; P = 0.170) and non-significant higher miscarriage rate (26%; 19% and 14% respectively for low, normal and high age-specific groups; P = 0.209). However, it must be pointed out that in low age-specific AMH the initial FSH doses used for stimulation were higher than in the other groups.

Conclusion

This study shows that the age-specific levels of AMH have only a slight effect on IUI outcome when adapting the stimulation protocols to their level.

The role of anti-Müllerian hormone in prediction of pregnancy in young and older women with unexplained infertility undergoing intrauterine insemination

BACKGROUND

Serum anti-Müllerian hormone (AMH) level is considered to be a reliable marker of ovarian reserve. However, there are conflicting reports on the role of AMH level in predicting pregnancy after intrauterine insemination (IUI) cycles. The aim of this study is to investigate the clinical value of AMH in predicting pregnancy in younger and older women with unexplained infertility undergoing gonadotropin stimulation and IUI.

METHODS

The medical records of 84 women who underwent first gonadotropin-stimulated IUI cycle owing to unexplained infertility were retrospectively evaluated. The relation of AMH levels with clinical pregnancy rate was analyzed.

RESULTS

The overall clinical pregnancy rate was 19%. There was no significant difference in AMH levels between the pregnant and nonpregnant women (2.0 ± 1.0 vs 2.8 ± 2.0 ng/mL, respectively, p = 0.250). A further analysis according to age also failed to reveal significant differences in AMH levels between pregnant and nonpregnant women for both the younger (<35 years, n = 61) and the older (≥35 years, n = 23) subgroups (p = 0.714 and 0.532, respectively). Post-hoc power analysis showed a power of 0.80 with a 5% level of significance and a 0.8 effect size.

CONCLUSION

These findings indicate that AMH levels cannot predict pregnancy in women with unexplained infertility undergoing gonadotropin-stimulated IUI cycle. In addition, AMH is not a strong predictive factor for pregnancy either in younger or older women.

Effect of Gonadotropin Types and Indications on Homologous Intrauterine Insemination Success: A Study from 1251 Cycles and a Review of the Literature

Objective

To evaluate the IUI success factors relative to controlled ovarian stimulation (COS) and infertility type, this retrospective cohort study included 1251 couples undergoing homologous IUI.

Results

We achieved 13% clinical pregnancies and 11% live births. COS and infertility type do not have significant effect on IUI clinical outcomes with unstable intervention of various couples' parameters, including the female age, the IUI attempt rank, and the sperm quality.

Conclusion

Further, the COS used seemed a weak predictor for IUI success; therefore, the indications need more discussion, especially in unexplained infertility cases involving various factors. Indeed, the fourth IUI attempt, the female age over 40 years, and the total motile sperm count <5 × 10⁶ were critical in decreasing the positive clinical outcomes of IUI. Those parameter cut-offs necessitate a larger analysis to give infertile couples more chances through IUI before carrying out other ART techniques.

Impact of thyroid autoimmunity in euthyroid women on live birth rate after IUI

Study question

Does thyroid autoimmunity (TAI) predict live birth rate in euthyroid women after one treatment cycle in IUI patients?

Summary answer

TAI as such does not influence pregnancy outcome after IUI treatment.

What is known already

The role of TAI on pregnancy outcome in the case of IVF/ICSI is largely debated in the literature. This is the first study to address this issue in the case of IUI.

Study design, size, duration

This was a retrospective cohort study. A two-armed study design was performed: patients anti-thyroid peroxidase (TPO)+ and patients anti-TPO-. All patients who started their first IUI cycle in our fertility center between 1 January 2010 and 31 December 2014 were included. After exclusion of those patients with or being treated for thyroid dysfunction, 3143 patients were finally included in the study.

Participants/materials, setting, methods

After approval by the institutional review board we retrospectively included all patients who started their first IUI cycle in our center between 1 January 2010 and 31 December 2014 with follow-up of outcome until 31 December 2015. Patients with clinical thyroid dysfunction were excluded (thyroid-stimulating hormone (TSH) <0.01 mIU/l; TSH >5 mIU/l) as were patients under treatment with levothyroxine or anti-thyroid drugs. These patients were then divided into two main groups: patients anti-TPO+ and patients anti-TPO- (= control group). Live birth delivery after 25 weeks of gestation was taken as the primary endpoint of our study. As a secondary endpoint, we evaluated differences in live birth delivery after IUI according to different upper limits of preconception TSH thresholds (<2.5 and <5.0 mIU/l). Furthermore, the influence of thyroid function (TSH, free thyroxine (fT4)), anti-TPO status, age, smoking, BMI, parity, ovarian reserve (anti-mullerian hormone (AMH) and FSH), IUI indication and IUI stimulation on live birth rate was analyzed.

Main results and the role of chance

Between-group comparison did not show any significant difference between the anti-TPO+ and anti-TPO- group with respect to live birth delivery-, pregnancy- or miscarriage rate with odds ratio at 1.04 (95% CI: 0.63; 1.69), 0.98 (95% CI: 0.62; 1.55) and 0.74 (95% CI: 0.23; 2.39), respectively. In addition, there were no significant differences in live birth delivery-, pregnancy- or miscarriage rate when comparing subgroups according to TSH level (TSH ≥2.5 mIU/l vs. TSH <2.5 mIU/l) with an odds ratio at 1.05 (95% CI: 0.76; 1.47), 1.04 (95% CI: 0.77; 1.41) and  0.95 (95% CI: 0.47; 1.94), respectively.

Limitations, reasons for caution

This study was powered for the primary aim, live birth rate. The limitations of this study are the absence of region-specific reference ranges for thyroid hormones and the absence of follow-up of TSH values during ART and subsequent pregnancy. Moreover, there was a time difference of 5 months between thyroid assessment and the start of stimulation. The area where the study was conducted corresponds to a mild iodine deficient area and data should be translated with caution to areas with different iodine backgrounds.

Wider implications of the findings

Our findings indicate comparable pregnancy-, abortion- and delivery rates in women with and without TAI undergoing IUI. Moreover, we were unable to confirm a negative effect of TSH level above 2.5 mIU/l on live birth delivery rate. We therefore believe that advocating Levothyroxine treatment at TSH levels between 2.5 and 4 mIU/l needs to be considered with caution and requires further analysis in a prospective cohort study.

The Value of Anti-Müllerian Hormone in Predicting Clinical Pregnancy After Intrauterine Insemination

OBJECTIVES

To evaluate the utility of anti-Müllerian hormone (AMH) in predicting clinical pregnancy with intrauterine insemination (IUI) and compare it to other markers of quantitative ovarian reserve.

METHODS

Retrospective cohort study of women undergoing natural and stimulated IUI cycles. All patients achieved a clinical pregnancy within three IUI cycles or completed three IUI cycles without pregnancy. Receiver operating curves were generated to determine the ability of AMH, antral follicle count, age, BMI, and day 3 FSH to predict clinical pregnancy with IUI. Characteristics of those with and without pregnancy were compared using Mann-Whitney U, chi-square, and Fisher exact tests.

RESULTS

Of 209 women included, 49% achieved clinical pregnancy. Pregnant patients were more likely to have a higher AMH (2.76 vs. 1.55 ng/mL, P = 0.0004). The area under the curve was 0.642 in predicting clinical pregnancy within three IUI cycles using AMH (0.608 if excluding polycystic ovarian syndrome patients); 0.639 using antral follicle count; 0.549 using age; 0.599 using day 3 FSH; and 0.639 using BMI.

CONCLUSION

Although serum AMH appears significantly higher in women achieving clinical pregnancy, the predictive value of AMH alone was no better than that for other markers of quantitative ovarian reserve in a patient who clinically qualifies for IUI.
