Prediction value of anti-Mullerian hormone (AMH) serum levels and antral follicle count (AFC) in hormonal contraceptive (HC) users and non-HC users undergoing IVF-PGD treatment

Prediction of Fertilization Disorders in the In Vitro Fertilization/Intracytoplasmic Sperm Injection: A Retrospective Study of 106,728 Treatment Cycles

Purpose

This study aimed to develop a risk prediction of fertilization disorders during the in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).

Methods

A retrospective study was performed with 106,728 fresh embryo IVF/ICSI cycles from 2009 to 2019. Basic characteristics of patients, clinical treatment data, and laboratory parameters were involved. The associations between the selected variables and risks for low fertilization rate (LFR) and total fertilization failure (TFF) were investigated. Ordinal logistic regression and the receiver operating characteristic curves (ROCs) were used to construct and evaluate the prediction models.

Results

A total of 97,181 controls, 4,343 LFR and 5,204 TFF cases were involved in this study. The model based on clinical characteristics (the ages of the couples, women's BMI, types of infertility, ART failure history, the diminished ovarian reserve, sperm quality, insemination method, and the number of oocytes retrieved) had an AUC of 0.743 for TFF. The laboratory model showed that primary infertility, ART failure history, minimal-stimulation cycle/natural cycle, numbers of oocyte retrieved < 5, IVF, and Anti-Mullerian hormone (AMH) level < 1.1ng/ml are predictors of TFF, with an AUC of 0.742.

Conclusion

We established a clinical and a laboratory prediction model for LFR/TFF. Both of the models showed relatively high AUCs.

Anti-Müllerian hormone levels among contraceptive users: evidence from a cross-sectional cohort of 27,125 individuals

BACKGROUND

Anti-Müllerian hormone has become the clinical biomarker-based standard to assess ovarian reserve. As anti-Müllerian hormone testing becomes more common, more individuals are seeking to interpret the values obtained while using contraceptives. To appropriately counsel women, a better understanding of anti-Müllerian hormone levels in women using different contraceptives is needed.

OBJECTIVE

To study the association between different forms of contraceptives and anti-Müllerian levels in women of reproductive age.

STUDY DESIGN

This is a cross-sectional study including 27,125 US-based women aged 20 to 46 years, accessing reproductive hormone results through Modern Fertility and who provided informed consent to participate in the research. Anti-Müllerian hormone levels were collected through dried blood spot card (95.9%) or venipuncture (4.1%), and previous work has shown high correlation between hormone levels collected by these 2 methods. Multiple linear regressions were run to compare anti-Müllerian hormone levels in women using contraceptives with women not on any contraceptive, controlling for age, age of menarche, body mass index, smoking, sample collection method, cycle day, and self-reported polycystic ovary syndrome diagnosis. We also analyzed whether duration of contraceptive use predicted anti-Müllerian hormone levels in users of the hormonal intrauterine device and combined oral contraceptive pill, given the size of these contraceptive groups.

RESULTS

Mean anti-Müllerian hormone levels were statistically significantly lower in women using the combined oral contraceptive pill (23.68% lower; coefficient, 0.76; 95% confidence interval, 0.72-0.81; P<.001), vaginal ring (22.07% lower; coefficient, 0.78; 95% confidence interval, 0.71-0.86; P<.001), hormonal intrauterine device (6.73% lower; coefficient, 0.93; 95% confidence interval, 0.88-0.99; P=.014), implant (23.44% lower; coefficient, 0.77; 95% confidence interval, 0.69-0.85; P<.001), or progestin-only pill (14.80% lower; coefficient, 0.85; 95% confidence interval, 0.76-0.96; P=.007) than women not on any contraceptive when controlling for covariates. Anti-Müllerian hormone levels were not significantly different when comparing women not using any contraceptives to those using the copper intrauterine device (1.57% lower; coefficient, 0.98; 95% confidence interval, 0.92-1.05, P=.600). Associations between contraceptive use and anti-Müllerian hormone levels did not differ based on self-reported polycystic ovary syndrome diagnosis. Duration of hormonal intrauterine device use, but not of combined oral contraceptive pill use, was slightly positively associated with anti-Müllerian hormone levels, although this small magnitude effect is likely not clinically meaningful (coefficient, 1.002; 95% confidence interval, 1.0005-1.003; P=.007).

CONCLUSION

Current hormonal contraceptive use is associated with a lower mean anti-Müllerian hormone level than that of women who are not on contraceptives, with variability in the percent difference across contraceptive methods. These data provide guidance for clinicians on how to interpret anti-Müllerian hormone levels assessed while on contraceptives and may facilitate more patients to continue contraceptive use while being evaluated for their ovarian reserve.

The effect of vitamin D status on ovarian reserve markers in infertile women: A prospective cross-sectional study

Background

Vitamin D deficiency and infertility are two important health problems in Iran. Some studies suggest that vitamin D may influence Anti-Müllerian hormone (AMH) and antral follicle count (AFC) as an ovarian reserve.

Objective

The present study aimed to investigate the impact of vitamin D on AMH serum concentrations/AFC.

Materials and Methods

Three hundred and five infertile women referred to the IVF Unit of Yas hospital, between July and December 2017, were enrolled in this cross-sectional study. The demographic characteristics of the participants, as well as the serum levels of vitamin D, AMH, and ultrasonic examination of AFC were recorded.

Results

Finally, 287 infertile women were included in the analysis with a mean age of 29.95 ± 4.73 yr (18-45 yr) and a mean Body mass indexof 25.11 ± 4.41 kg/m 2 . The median AMH and vitamin D levels were 3.20 and 22.82 ng/ml, respectively. Considering the cut-off level of 20 ng/ml, 58.7% were vitamin D deficient. Regression analysis showed no association between AMH and vitamin D levels (p = 0.161), even after adjusting for baseline variables (p = 0.182). A total of 120 patients had an AFC < 6 and 164 ≥ 6, which was not statistically different between the groups with normal level or deficient vitamin D (p = 0.133).

Conclusion

The present cross-sectional study showed no significant association between serum levels of vitamin D and AMH or AFC in infertile women, even after adjusting for baseline variables.
