The circulating alarin level was elevated in infertile women with poor ovarian reserve.

Objective: We aimed to reveal the association of serum alarin level with POR status of the infertile women in the present study.

Methods: The eligibility criteria for this prospective cross-sectional study included a total of 92 infertile women attending the Hitit University Hospital, and all participant women were categorized into two main groups of ovarian reserve: (i) Poor ovarian reserve (POR) group ( = 40) based on ESHRE consensus and (ii) Control group (NOR) ( = 52).

Results: The mean adjusted-ages and BMI values of the NOR and POR groups were statistically comparable ( = .057 and  .600, respectively). The mean E2, FSH, and LH levels were elevated in the POR group ( < .001, for all). The mean AFC and AMH concentration were significantly reduced in the POR group ( < .001, for both). In addition, there was a significant increase in the serum alarin level in the POR group ( < .001). Pearson's analysis revealed that the mean BMI value of the POR group had a weak and negative correlation ( = 0.318,  = .046). Also, there was no correlation between serum alarin with E2 and FSH levels in both study groups. A weak and positive correlation was found between serum alarin and LH concentration only in the POR group ( = 0.318,  = .045). The mean AMH and AFC values were not significantly correlated with serum alarin levels.

Conclusion: The circulating alarin level was significantly elevated in infertile women with POR patterns. In addition, the alarin level was significantly correlated with the serum LH concentration in the POR pattern.
