Correlation of serum Anti-Müllerian hormone concentrations on day 3 of the in vitro fertilization stimulation cycle with assisted reproduction outcome in polycystic ovary syndrome patients

PURPOSE

To investigate whether serum Anti- Müllerian hormone (AMH) on day 3 could predict controlled ovarian stimulation and reproductive outcomes in women with polycystic ovary syndrome.

METHODS

A total of 164 PCOS patients undergoing their first IVF treatment cycle were prospectively included. Serum AMH levels on cycle day 3 was measured. The controlled ovarian stimulation and clinical outcomes for the study population were divided according to the <25th, 25 to 75th, or >75th percentile of serum day-3 AMH.

RESULTS

Estradiol levels on hCG day and the number of retrieved oocytes significantly increased with increasing serum AMH levels, while total consumption of gonadotropin dose showed a significant decrease (P < 0.05). Fertilization rate and the number of good quality embryos were comparable among the low, average and high groups (P > 0.05). Embryo implantation rates in the high AMH group was significantly inferior to those with low and average AMH concentration (27 versus 48.8 and 50%, P < 0.01). Clinical pregnancy rates was lower in the high AMH group than that of the low and average group (45.9 versus 65 and 66.7%, P = 0.09), but this difference was only close to statistical significance. In addition, ordinal regression analysis indicated that LH level was the only independent predictor of embryo implantation rates (P = 0.017).

CONCLUSIONS

In PCOS women, AMH levels on day 3 of the IVF stimulation cycle positively predict ovarian response to gonadotrophins. However, the women with high AMH levels had a significantly decreased IR, which may be due to remarkably increased LH concentrations.

PCOS and peripheral AMH levels in relation to FSH receptor gene single nucleotide polymorphisms

OBJECTIVES

To determine if an association exists between the follicle-stimulating hormone receptor (FSHR) gene p.Asn680Ser polymorphism and polycystic ovary syndrome (PCOS) or with high anti-mullerian hormone (AMH) levels without PCOS.

PATIENTS

Fifty-eight women with PCOS, 24 women with high AMH (>44.5 pmol/L) without PCOS and 80 healthy ethnically matched female controls.

MAIN OUTCOME MEASURES

Prevalence of the FSHR p.Asn680Ser polymorphism, baseline serum AMH levels and response to ovulation induction with clomiphene citrate.

RESULTS

The frequency of FSHR p.Asn680Ser genotypes were not significantly different between PCOS patients, patients with high AMH without PCOS and controls (p = 0.88). Of the women with PCOS, 34/58 were on clomiphene citrate treatment and 12/34 were resistant. There was no association between sensitivity or resistance to clomiphene and p.Asn680Ser genotypes (p = 0.38).

CONCLUSIONS

There is no evidence that FSHR p.Asn680Ser genotypes are associated with PCOS, high AMH levels or response to clomiphene citrate.

The effect of follicular antimullerian hormone levels of non-obese, non-hyperandrogenemic polycystic ovary syndrome patients on assisted reproduction outcome

Our aim is to investigate the follicular fluid concentrations of antimullerian hormone and its effect on assisted reproductive technology (ART) outcome in non-obese, non-hyperandrogenemic polycystic ovary syndrome patients. Subjects were categorized according to in vitro fertilization (IVF) indications: Group 1 PCOS (n:16), Group 2 male factor infertility (n:19) and Group 3 unexplained infertiliy patients (n:19). Follicular fluid antimullerian hormone levels (FF AMH) on the day of oocyte retrieval were analysed and ART outcome was studied. FF AMH levels in group 1, 2 and 3 were 35.70 ng/ml (median); 17.90 ng/ml (median); 17.90 ng/ml (median), respectively (p = 0.18). There were correlations between the FF AMH levels and follicle, oocyte, 2PN and embryo numbers in pathophysiology of polycystic ovary syndrome (PCOS) patients (p = 0.012; 0.024; 0.027; 0.013 respectively). There were no correlations between the FF AMHand ART outcome parameters in group 2 and 3. FF AMH levels were not different between the groups who were pregnant or not (p = 0.06). In conclusion there were no significant differences in terms of FF AMH levels in the three groups. FF AMH levels can predict the recovery of oocytes but not oocyte quality, embryo quality or pregnancy in non-obese non-hyperandrogenemic PCOS patient.

Serum anti-Müllerian hormone as a predictive marker of polycystic ovarian syndrome

Background

The anti-Müllerian hormone (AMH) is a dimeric protein secreted by the female ovaries and has two fundamental roles in follicle genesis. It delays the entrance of the primordial follicle into the pool of follicles in growth and diminishes the sensitivity of the ovarian follicle towards follicle-stimulating hormone (FSH). The purpose of this work was to study the AMH (nv 2.0–6.8 ng/mL) as a marker during assisted reproductive technology (ART), in order to identify cases of infertility due to polycystic ovarian syndrome (PCOS). This syndrome affects 10% of women with infertility problems, and a new biological marker could be useful to general practitioners of internal medicine to help generate the suspicion of PCOS so that they can refer the patient to the gynecologist for confirmation.

Methods

This study enrolled 236 patients aged 26–46 years undergoing assisted reproductive technology at the Institute for Maternal and Child Health, Trieste, Italy. On the third day of the ovarian cycle, the patients were given doses of AMH, FSH, and luteinizing hormone (LH, in cases of AMH < 2.0–6.8 ng/mL). A control pelvic ultrasound was also carried out.

Results

We identified 57 patients who were starting in vitro fertilization or embryo transfer with AMH values within the normal range (3.64 ± 1.51 ng/mL), 77 with values below normal (1.38 ± 0.32 ng/mL), and 96 cases with undetectable values of AMH. Six patients had very high AMH levels (10.0 ± 2.28 ng/mL) and, of these, five were found to have PCOS on pelvic ultrasound examination (P < 0.05). We also found inverse correlations between AMH levels and age (r = −0.52) and between AMH and FSH levels (r = −0.32).

Conclusion

In clinical practice it is common to encounter patients who turn to medicine in search of a cure for female infertility. In our experience, AMH two or three times the normal amount (10 ± 2.28 ng/mL), is a good indication of PCOS and infertility.

[Anti-Mullerian hormone and polycystic ovary syndrome]

Anti-Müllerian hormone (AMH) is known to be secreted in women by granulosa cells of growing follicles from the primary to the large antral follicle stage. Serum and intrafollicular AMH levels are elevated in patients with polycystic ovary syndrome (PCOS) due to increased number of small follicles and an increased secretion within each of these small follicles. This excess of AMH is strongly suspected to play a role in the follicular arrest of PCOS by a negative action on aromatase expression and on action of FSH. The interest of serum AMH assay is also clinically important because AMH level is more sensitive, more specific and reproducible from one center to another as the follicle count. Rates above 5ng/ml or 35pmol/l may be considered as a diagnostic criterion for PCOS.

Anti-Mullerian hormone confirms the novel classification of female functional androgenization including polycystic ovary syndrome

OBJECTIVE

Functional androgenization (FA) can be divided into five groups corresponding to the predominant organ pathology as recently shown by our group: functional cutaneous androgenization (FCA, skin) and FA syndrome (FAS) I (ovary, lean individual), II (adrenal gland), III (ovary, fat tissue, pancreas, and hyperinsulinemia), and IV (residual FA dysfunctions). Group-specific clusters are based on primary variables such as LH, testosterone, DHEAS, sex hormone-binding globulin (SHBG), body mass index (BMI), glucose, insulin, and enlarged polyfollicular ovaries. Because anti-Müllerian hormone (AMH) positively correlates with the antral follicle count, its relevance as an additional primary variable for classifying FA was investigated.

DESIGN

In this study, 178 patients with FA were consecutively enrolled and classified into the five FA groups as described earlier and 30 women with regular menstrual cycles served as control.

METHODS

Primary variables and serum AMH were analyzed in the early follicular phase.

RESULTS

FA patients showed significantly elevated AMH levels (11.1±6.7 ng/ml) versus control (3.0±2.0 ng/ml; P<.0001). AMH was significantly increased in groups FAS I (15.6±5.8 ng/ml) and FAS III (11.6±6.6 ng/ml) compared with groups FCA (7.0±3.8 ng/ml), FAS II (5.05±3.0 ng/ml), and FAS IV (6.9±4.6 ng/ml) and correlated positively (P<.0001) with LH (r=0.538) and testosterone (r=0.368). In regression and multivariate analyses, AMH was not dependent on SHBG, DHEAS, BMI, glucose, or insulin. In receiver operating characteristic analysis, 9.21 ng/ml AMH showed 90% specificity with 71.2% sensitivity for the diagnosis of the two ovarian FA groups, FAS I and III.

CONCLUSION

AMH confirms the novel stratification system and constitutes a useful primary variable in the algorithm of FA classification.

Impact of laparoscopic ovarian drilling on anti-Müllerian hormone levels and ovarian stromal blood flow using three-dimensional power Doppler in women with anovulatory polycystic ovary syndrome

OBJECTIVE

To evaluate the effect of laparoscopic ovarian drilling (LOD) on plasma levels of anti-Müllerian hormone (AMH) and ovarian stromal blood flow changes, by using three-dimensional power Doppler ultrasonography, in polycystic ovary syndrome (PCOS).

DESIGN

Prospective controlled study.

SETTING

Taiba hospital, Kuwait.

PATIENT(S)

Twenty-three anovulatory clomiphene citrate (CC)-resistant women with PCOS and 20 fertile women as a control group.

INTERVENTION(S)

Laparoscopic ovarian drilling.

MEAN OUTCOME MEASURE(S)

Serum levels of AMH, ovarian three-dimensional power Doppler indices (vascularization index, flow index, and vascularization flow index) and occurrence of ovulation or pregnancy.

RESULT(S)

Plasma AMH and power Doppler indices of ovarian stromal blood flow were significantly higher in the PCOS group than in the control group. Plasma AMH and ovarian stromal blood flow Doppler indices were significantly reduced in the PCOS group after LOD. Women who ovulated after LOD had a significantly lower preoperative AMH compared with the nonresponders. There was a significant positive correlation between AMH and power Doppler flow indices before and after LOD in PCOS group.

CONCLUSION(S)

Measuring AMH and ovarian stromal three-dimensional power Doppler blood flow for women with anovulatory PCOS undergoing LOD may provide a useful tool in evaluating the outcome of LOD.

Extra- and intra-ovarian factors in polycystic ovary syndrome: impact on oocyte maturation and embryo developmental competence

BACKGROUND

Polycystic ovary syndrome (PCOS) is a common metabolic dysfunction and heterogeneous endocrine disorder in women of reproductive age. Although patients with PCOS are typically characterized by increased numbers of oocytes retrieved during IVF, they are often of poor quality, leading to lower fertilization, cleavage and implantation rates, and a higher miscarriage rate.

METHODS

For this review, we searched the database MEDLINE (1950 to January 2010) and Google for all full texts and/or abstract articles published in English with content related to oocyte maturation and embryo developmental competence.

RESULTS

The search showed that alteration of many factors may directly or indirectly impair the competence of maturating oocytes through endocrine and local paracrine/autocrine actions, resulting in a lower pregnancy rate in patients with PCOS. The extra-ovarian factors identified included gonadotrophins, hyperandrogenemia and hyperinsulinemia, although intra-ovarian factors included members of the epidermal, fibroblast, insulin-like and neurotrophin families of growth factors, as well as the cytokines.

CONCLUSIONS

Any abnormality in the extra- and/or intra-ovarian factors may negatively affect the granulosa cell-oocyte interaction, oocyte maturation and potential embryonic developmental competence, contributing to unsuccessful outcomes for patients with PCOS who are undergoing assisted reproduction.

Serum antimüllerian hormone concentrations on day 3 of the in vitro fertilization stimulation cycle are predictive of the fertilization, implantation, and pregnancy in polycystic ovary syndrome patients undergoing assisted reproduction

OBJECTIVE

To determine the possible relationship between serum antimüllerian hormone (AMH) concentrations on day 3 and controlled ovarian stimulation and reproductive outcomes in women with polycystic ovary syndrome.

DESIGN

Prospective, clinical trial.

SETTING

University hospital.

PATIENT(S)

Sixty women with PCOS.

INTERVENTION(S)

Serum concentrations of AMH measured on cycle day 3.

MAIN OUTCOME MEASURE(S)

Clinic pregnancy rate (CPR), implantation rate (IR), and fertilization rate (FR).

RESULT(S)

The CPR, IR, and FR were markedly different among the day-3 serum AMH groups (low, moderate, and high AMH groups). The CPR were 33.3, 46.1, and 60.0, respectively, in the low, moderate, and high serum AMH groups on day 3. The embryo IR were 18.6, 26.7, and 36.3, respectively. The FR were 54, 68, and 79, respectively. An AMH level≥3.01 ng/mL was shown to predict FR with a sensitivity of 86.4% and specificity of 75%. An AMH level≥3.2 ng/mL was shown to predict IR and CPR with sensitivity and specificity of 72.1% and 72.7%, and 75.6% and 77.3%, respectively.

CONCLUSION(S)

On day 3 of the in vitro fertilization stimulation cycle, serum concentrations of AMH can be used as a marker for ovarian response as well as reproductive outcome in assisted reproductive cycles of PCOS patients.

Follicular-fluid anti-Mullerian hormone concentrations are predictive of assisted reproduction outcome in PCOS patients

Serum anti-Mullerian hormone (AMH) concentrations constitute a sensitive marker for ovarian ageing. In addition, concentrations of AMH in the follicular fluid constitute a useful marker of embryo implantation in assisted reproduction cycles. The present study measured serum and follicular-fluid AMH concentrations on the day of oocyte retrieval. These data showed that clinical pregnancy rates (25.0, 34.1 and 42.1%, respectively, P < 0.001), embryo implantation rates (24.3, 35.0 and 44.4%, respectively, P < 0.001) and fertilization rates (59.2, 70.9 and 79.5%, respectively, P < 0.001) were markedly different among the low, moderate and high follicular-fluid AMH groups but not among the different serum AMH concentration groups. Follicular-fluid AMH concentrations were negatively correlated with follicular-fluid oestradiol concentrations. The results of this study suggest that follicular-fluid AMH concentration on the day of oocyte retrieval would appear to better reflect the reproductive outcome in PCOS patients undergoing assisted reproduction.

Serum and follicular anti-Mullerian hormone levels in women with polycystic ovary syndrome (PCOS) under metformin

BACKGROUND

No data regarding metformin effects on follicular fluid anti-Müllerian hormone (AMH) levels were to date available in literature. The aim of the present study was to evaluate in patients with polycystic ovary syndrome (PCOS) whether metformin administration affects serum and follicular AMH levels, and whether this is related to ovarian response to the treatment.

METHODS

Twenty young patients with PCOS who had received metformin were enrolled. Ten patients were anovulatory (Met-anov group), whereas the other 10 were ovulatory (Met-ov group) but had failed to conceive. Further untreated PCOS (PCOS controls, n. 10) and healthy controls (non-PCOS controls, n. 10) who were scheduled for laparoscopic surgery were enrolled. In each subjects, clinical and biochemical evaluations were performed. AMH concentrations in blood and antral follicular fluid were assayed.

RESULTS

In both Met-anov and Met-ov groups, and without difference between them, serum androgens and AMH, and indices of insulin resistance were significantly (p < 0.05) improved after treatment. On the other hand, significant differences (p < 0.05) between the two groups were detected with respect to the same biochemical parameters in antral follicular fluid. In the Met-anov group, no significant correlation was observed between AMH concentrations in the follicular fluid and variation in serum androgens, AMH and insulin resistance indexes; whereas in Met-ov group significant correlations were detected between AMH levels in the follicular fluid and variation in serum androgens, AMH and insulin resistance indexes.

CONCLUSIONS

Metformin administration in patients with PCOS exerts a differential action on the ovarian AMH levels on the basis of ovulatory response. Changes in AMH levels in antral follicular fluid during metformin treatment could be involved in the local mechanisms mediating the ovulatory restoration.

Anti-Müllerian hormone and polycystic ovary syndrome: a mountain too high?

Anti-Müllerian hormone (AMH) was initially thought to be produced solely by the foetal male during sexual differentiation to promote regression of the Müllerian ducts. Over the last decade, however, a new and interesting role has emerged for AMH in the ovary. In human ovaries, AMH is produced by granulosa cells from 36 weeks of gestation until menopause, with the highest expression being in small antral follicles. AMH production gradually declines as follicles grow; once follicles reach a size at which they are dominant, it has largely disappeared. Its removal from these larger follicles appears to be an important requirement for dominant follicle selection and progression to ovulation as AMH has an inhibitory role in the ovary, reducing both primordial follicle initiation and follicle sensitivity to FSH by inhibition of aromatase. It is for this reason that AMH is a focus of interest in polycystic ovary syndrome (PCOS). Serum levels are doubled, and granulosa cell production is greatly increased. Interestingly, there appear to be two groups of women with PCOS who can be distinguished by their AMH level: one group consists of those who have high levels which do not reduce with treatment and who respond less well to induction of ovulation, and a second group consists of those in whom the level is less elevated and reduces on treatment and who seem to respond rather better. Understanding the reason for the raised AMH in PCOS may give clues as to the mechanism of anovulation. To conclude, AMH appears to have a major inhibitory role during folliculogenesis, which may contribute to anovulation in PCOS.
