This study hypothesized that oxidative stress in women with diminished ovarian reserve (DOR) can influence in vitro fertilization (IVF) outcomes. Therefore, we investigated the effect of intraovarian platelet-rich plasma (PRP) administration on the oxidative stress state in follicular fluid in DOR patients. Following the follow-up of a retrospective cohort study, follicular fluid was isolated from twenty-five DOR patients. The total antioxidant capacity (TAC), catalase (CAT), and superoxide dismutase (SOD) activities, total oxidant status (TOS), and malondialdehyde (MDA) levels were measured before and after intraovarian PRP administration using colorimetric methods. The levels of estradiol (E2), anti-mullerian hormone (AMH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were measured at baseline and after two menstrual cycles. The quantity and quality of oocytes and embryos were assessed at both stages.Following intraovarian PRP injection, an increase in TAC levels, elevated CAT and SOD activities, and a decline in TOS and MDA content in the follicular fluid of DOR women were observed. AMH and E2 hormone levels also increased post-treatment.Additionally, a relative increase in the number and quality of oocytes and embryos was observed after a single PRP injection. Intraovarian PRP injection improves the oxidative state of follicular fluid and potentially enhances IVF outcomes in DOR women.

Objective: Reactive oxygen species (ROS) are produced during cryopreservation of human sperm and impair sperm function. Antioxidant compounds, such as fennel and purslane, reduce the damaging effects of ROS. This study aimed to evaluate motility parameters, plasma membrane integrity (PMI), mitochondrial membrane potential (MMP), intracellular ROS, and DNA damage to determine the optimum concentrations of hydroalcoholic extracts of fennel and purslane for human spermatozoa cryopreservation. Methods: Twenty human sperm samples were used and divided into seven equal groups consisting of fennel hydroalcoholic extract (5, 10, and 15 mg/L), purslane hydroalcoholic extract (25, 50, and 100 mg/L), and no additive. Results: Supplementation of 25 mg/L and 50 mg/L purslane extract and 10 mg/L fennel extract in cryopreservation extender significantly increased the motility and PMI of sperm with a significant reduction in intracellular ROS compared to control groups (p<0.05). A 50 mg/L concentration of purslane extract elevated progressive motility and MMP compared to the control group (p<0.05). No significant differences were seen for motion patterns and DNA damage of frozen-thawed human sperm in extender containing these extracts. Conclusion The results showed that supplementation of 50 mg/L purslane extract and 10 mg/L fennel extract in semen cryopreservation extender has the potential to decrease intracellular ROS and subsequently elevate the motility and PMI of human sperm.

Polycystic ovary syndrome (PCOS) is one of the most critical disorders, which affects approximately 20% of women of childbearing age and melatonin supplementation in these women can be effective. However, human studies in this area are particularly limited to IVF candidates. The aim of this clinical trial study was to evaluate the effect of melatonin on the in vitro fertilization (IVF) in PCOS involved women. In this clinical trial study, a total of 320 women with PCOS were randomly assigned to the intervention and control groups. Patients in the intervention group (n=160) received a combination of melatonin and metformin (3 mg and 500 mg, respectively) three times a day. The control group (n=160) received metformin 500 mg from the luteal phase of the cycle before the start of gonadotropin. Oocyte and embryo quality, number of oocytes, and pregnancy outcomes were compared in both groups. Our study revealed that the frequency of Metaphase II oocytes (69.9% vs. 57.9%, p＜0.001) and the number of embryos of the top-quality (grade A) were higher in the group treated with melatonin (40.3% vs. 29.9%, p=0.001). The rate of clinical pregnancy and implantation were also higher in the intervention group. The odds of clinical pregnancy in the intervention group was 1.8 times (p=0.039). Moreover, oral melatonin supplementation was effective in patients with PCOS, who were candidates for IVF because of the increased quality of mature oocytes, top-quality embryos, and increased odds of clinical pregnancy.
