After laparoscopic stripping of endometrioma, intracorporeal suturing showed less damage on ovarian reserve as compared with bipolar electrocoagulation. Therefore, hemostatic suturing technique may be considered as a better choice after laparoscopic ovarian cystectomy.

Background Endometriosis is a chronic and relatively common disease in women of childbearing age. Complications of this disease include a wide range of disorders. The cause of this disease is not known for sure, but several hypotheses have been proposed for it. Aim In this review, an attempt has been made to discuss the effects of oxidative stress on various complications of endometriosis. Content In endometriosis, the entry of endometrial tissues into the peritoneal cavity causes oxidative stress through the Fenton reaction and inflammation in this site. Fenton reaction can produce reactive oxygen species through a catalytic form of iron. This process can provoke inflammatory responses and oxidative injury. As a result, the activity of macrophages and expression of nuclear factor‐kappa B increase. Oxidative stress can be associated with many complications of endometriosis. It has been reported that in the peritoneal fluid of endometriosis patients, there are activated macrophages, growth factors, and high concentrations of cytokines. These conditions act as a toxic to embryo survival and sperm function. Implications Novel therapeutic strategies must regulate intracellular ROS signaling to inhibit the adverse effects of ROS‐induced endometriosis‐promoting events. According to features of antioxidants, they may inhibit early events of the development of endometriosis.

Background: Asherman’s syndrome (AS) is a rare reproductive abnormality, resulting in endometrial collapse due to aggressive or recurrent endometritis and/or curettage. Objective: We aimed to assess the effectiveness of using platelet-rich plasma (PRP) to lower the recurrence rate of intrauterine adhesions (IUAs) following postlysis hysteroscopy. Materials and Methods: In a nonrandomized controlled study, women aged 20-45 years with AS diagnosed by sonohysterography, 3D sonography, hysteroscopy, or uterosalpingography between May 2018 and September 2018 were included. Patients (n = 30) were divided into case and control groups. Following hysteroscopic adhesiolysis, a Foley catheter was placed into the uterine cavity in all women. After two days, the catheter was removed, and 1-mL PRP was injected into the uterine cavity of women in the PRP (case) group, while the control received no PRP. All controls and subjects underwent diagnostic hysteroscopy 8-10 weeks following the intervention to assess the IUAs according to the American Society for Reproductive Medicine scoring system. Result: Our results did not reveal any significant difference in the menstrual pattern of either the control or test groups before or after treatment (p = 0.2). Moreover, the IUA stage in both studied groups before and after treatment was similar (p = 0.2). The duration of menstrual bleeding in both studied groups before and after treatment was also similar. Conclusion: PRP cannot decrease the menstrual pattern or development of postsurgical IUAs, as evaluated by follow-up hysteroscopy. Key words: Asherman’s syndrome, Platelet-rich plasma, Pregnancy rate.

Objective Previous studies investigating the association between angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and recurrent pregnancy loss (RPL) risk has provided inconsistent results. The aim of our study was to assess the association between the ACE I/D polymorphism and risk of RPL. Methods All studies published up to January 30, 2018 on the association of ACE I/D polymorphism with RPL were identified by searching the PubMed, Web of Knowledge, and Google scholar databases. Results A total of 26 case-control studies with 3,140 RPL cases and 3,370 controls were included in the meta-analysis. Overall, there was a significant association between ACE I/D polymorphism and RPL risk under the allele model (I versus D: odds ratio [OR] = 0.538, 95% confidence interval [CI] = 0.451–0.643, p ≤ 0.001), the homozygote model (II versus DD: OR = 0.766, 95% CI = 0.598–0.981, p = 0.035) and the recessive model (II versus ID + DD: OR = 0.809, 95% CI = 0.658–0.994, p = 0.044). Subgroup analysis by ethnicity showed that there was a significant association between ACE I/D polymorphism and increased risk of RPL in Caucasian and West-Asian populations, but not in East-Asians. When stratified by number of recurrent miscarriages (RMs), a significant association between ACE I/D polymorphism and increased risk of RPL was detected in the group of studies with ≥ 2 RMs, but not in studies with ≥ 3 RMs. Conclusion The meta-analysis suggests that ACE I/D polymorphism is associated with increased risk of RPL. The ACE I/D polymorphism may be a risk factor for RPL in Caucasian and West-Asian populations, but not in East-Asians.
