Brief Summary

Oxidative stress has been investigated as a key factor in the pathogenesis and progression of endometrioma. High follicular fluid ROS levels and serum can be related to negative IVF/ICSI outcomes in infertile women with endometrioma. Therefore, the use of antioxidants such as N-acetyl cysteine (NAC) may be reduced complications of endometrioma. To study this hypothesis, we designed a double-blind, randomized clinical trial study that aimed to determine the effect of N-acetyl cysteine (NAC) on stress oxidative factors and pregnancy outcomes in IVF/ICSI cycles in endometrioma patients.

Outcome Measures

Primary Outcomes (1)

  • MII oocyte number and quality

    Observation of oocytes that were mature at the time of oocyte collection

    Immediately after oocyte puncture

Secondary Outcomes (8)

  • Measurement of TAC oxidative stress marker in blood plasma

    Before intervention and 6 weeks after intervention

  • Measurement of SOD oxidative stress marker in blood plasma

    Baseline and 6 weeks after intervention

  • Measurement of TAC oxidative stress marker in folicular fluid

    Immediately After oocyte puncture

  • Measurement of SOD oxidative stress marker in folicular fluid

    Immediately After oocyte puncture

  • Cleaved embryo numbers

    2-3 days after oocyte puncture

  • +3 more secondary outcomes

Study Arms (2)

N-acetyl cystein

EXPERIMENTAL

Seventy participants who randomly assigned in the intervention group, during 6 weeks simultaneous to start standard long agonist protocol or antagonist induction, will be received 1200 (2×600) mg of effervescent tablets of NAC daily. Plasma blood will collect before the intervention and at the time of oocyte retrieval (end of 6 week), in addition to, follicular fluid will be obtained from the mature follicles. Also, we will measure severity of dysmenorea by visual analogue scale (VAS) technique.

Drug: N-acetyl cysteine

effervescent placebo

PLACEBO COMPARATOR

Seventy participants who randomly assigned to the control group, during 6 weeks simultaneous to start the standard long agonist protocol, or antagonist induction, will be received 1200 (2×600) mg of effervescent placebo tablets daily. Plasma blood will collect before the intervention and at the time of oocyte retrieval, in addition to, follicular fluid will be obtained from the mature follicles. Also, we measure severity of dysmenorrhea by visual analogue scale (VAS) technique.

Drug: placebo

Interventions

One hundred and forty participants randomize in the intervention and placebo groups, during 6 weeks simultaneous to start standard long agonist protocol or antagonist induction. They will be received 1200 (2×600) mg of effervescent tablets of NAC or placebo daily. Plasma blood will collect before the intervention and at the time of oocyte retrieval (end of 6 week), in addition to, follicular fluid will be obtained from the mature follicles.
