RESUMEN
INTRODUCTION: Diminished ovarian reserve (DOR) presents a complex challenge in the field of infertility, with factors like age and genetics traditionally under scrutiny. However, the potential influence of adverse childhood experiences on ovarian reserve remains a relatively unexplored area. This research aims to contribute novel insights to the understanding of diminished ovarian reserve etiology, shedding light on previously unexplored risk factors and their potential implications. DESIGN: This case-control study was conducted at an Assisted Reproductive Technology (ART) Center of a university hospital. Infertile patients admitted to the ART center were enrolled in the study. The case group consisted of 102 infertile women diagnosed with diminished ovarian reserve, and the control group consisted of 103 healthy women with male factor infertility. An interview lasting approximately 30 min was held in a separate room with those who volunteered to participate in the study. Due to the sensitivity of the research subject, the data was collected anonymously. The Childhood Trauma Questionnaire was used to measure adverse childhood experiences, and the Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety and depression in the study. The results were compared between the case and the control groups. RESULTS: Overall, the total score of the Childhood Trauma Questionnaire and all subscale scores were higher in the case group (38.28 ± 9.86) than in the control group (35.10 ± 9.52). According to HADS, the total score was 15.92 ± 7.98 in the case group and 14.22 ± 6.87 in the control group. CONCLUSIONS: Our pioneering study is designed to investigate a previously unexplored risk factor in low ovarian reserve. Considering our data and other studies in the literature examining childhood traumas as a risk, it makes us think that the issue is worth examining.
RESUMEN
Dehydroepiandrosterone (DHEA) is frequently integrated as an adjuvant in over a quarter of controlled ovarian hyperstimulation (COH) protocols, despite the ongoing debate regarding its impact. This study aimed to evaluate the efficacy and mechanism of action of DHEA on ovarian follicular development and ovarian response in rats with varying ovarian reserves. The study involved 75 rats categorized into 15 distinct groups. The ovarian tissues of rats in both the normal ovarian reserve group and the premature ovarian insufficiency (POI) group, induced by 4-vinylcyclohexene diepoxide (VCD) injection, were subjected to histomorphological and biochemical analyses following the administration of DHEA, either alone or in combination with COH. Follicle counting was performed on histological sections obtained from various tissues. Serum concentrations of anti-Müllerian hormone (AMH) and the quantification of specific proteins in ovarian tissue, including phosphatase and tensin homolog of chromosome 10 (PTEN), phosphoinositide 3-kinase (PI3K), phosphorylated protein kinase B (pAKT), cyclooxygenase 2 (COX-2), caspase-3, as well as assessments of total antioxidant status and total oxidant status, were conducted employing the ELISA method. The impact of DHEA exhibited variability based on ovarian reserve. In the POI model, DHEA augmented follicular development and ovarian response to the COH protocol by upregulating the PTEN/PI3K/AKT signaling pathway, mitigating apoptosis, inflammation, and oxidative stress, contrary to its effects in the normal ovarian reserve group. In conclusion, it has been determined that DHEA may exert beneficial effects on ovarian stimulation response by enhancing the initiation of primordial follicles and supporting antral follicle populations.

OBJECTIVE: To demonstrate the surgical approach for Müllerian agenesis with bilateral uterine remnants containing functional endometrium. DESIGN: Stepwise demonstration of the technique with narrated video footage. SETTING: Reproductive surgery unit of a tertiary university hospital. PATIENT: An 18-year-old adolescent was admitted to a tertiary university hospital with complaints of primary amenorrhea and cyclic pelvic pain. Physical examination and magnetic resonance imaging scans suggested a complex Müllerian abnormality. The patient had uterine remnants with bilateral functional endometrium and cervicovaginal agenesis. INTERVENTION: An operation was planned to reconstruct her anatomy by providing a neovagina and anastomosing the uterine remnants. Gonadotropin-releasing hormone analogs were prescribed to suppress her menstruation until the procedure. The operation was performed in the third month after the initial diagnosis. A laparoscopy was conducted, revealing approximately 5 × 6-cm bilateral uterine horns with healthy adnexa. As the first step, a neovagina was created using a modified peritoneal pull-down technique, a standard approach in our clinic. A vaginal incision was made, and a blind vaginal dissection was performed to reach the peritoneum vaginally. Subsequently, an acrylic vaginal mold was inserted. The vaginal orifice was laparoscopically incised using ultrasonic energy with guidance from the inserted vaginal acrylic mold. The orifice was gradually dilated with larger molds. The entire pelvic peritoneum was dissected circularly, and the distal part of the dissected peritoneum was pulled down using four 2.0 Vicryl sutures at 0°, 90°, 180°, and 270° from the opened vaginal orifice. The uterine cavities of both remnants were incised, and two separate Foley catheters were placed in both cavities. A mold with a hole was used to insert the catheters through the vagina. Both catheters were secured in the cavities with Prolene sutures pulled up from the anterior abdominal wall. The next step involved uterine anastomosis. The uterine remnants were unified through continuous suturing, resulting in the formation of a normally shaped uterus. In the final step, the created uterus and neovagina were anastomosed. The patient received instructions on how to perform mold exercises and follow-up care. MAIN OUTCOME MEASURE: Description of laparoscopic management of a rare Müllerian abnormality. RESULTS: The postoperative magnetic resonance imaging scan at 1 month revealed healed unified uterine cavities and vagina. The patient experienced spontaneous menstruation in the second month after surgery and now maintains regular menses with an approximately 9-10 cm functional vagina. Within 3 months after surgery, the visual analogue scale scores for chronic pelvic pain and dysmenorrhea decreased from 9 to 2-3. CONCLUSIONS: Müllerian abnormalities are exceptionally rare, and their spectrum is broad, making it challenging to identify an exact surgical method to restore functional anatomy. Therefore, a customized surgical approach should be designed for each patient on the basis of their unique condition.

BACKGROUND: An unexpected impaired ovarian response pertains to an insufficient reaction to controlled ovarian hyperstimulation. This deficient reaction is identified by a reduced count of mature follicles and retrieved oocytes during an IVF cycle, potentially diminishing the likelihood of a successful pregnancy. This research seeks to examine whether the characteristics of antral follicles can serve as predictive indicators for the unexpected impaired ovarian response to controlled ovarian stimulation (COS). METHODS: This retrospective cohort study was conducted at a tertiary university hospital. The electronic database of the ART (assisted reproductive technologies) center was screened between the years 2012-2022. Infertile women under 35 years, with normal ovarian reserve [anti-Müllerian hormone (AMH) > 1.2 ng/ml, antral follicle count (AFC) > 5] who underwent their first controlled ovarian stimulation (COS) cycle were selected. Women with < 9 oocytes retrieved (group 1 of the Poseidon classification) constituted the group A, whereas those with ≥ 9 oocytes severed as control (normo-responders) one (group B). Demographic, anthropometric and hormonal variables together with COS parameters of the two groups were compared. RESULTS: The number of patients with < 9 oocytes (group A) was 404, and those with ≥ 9 oocytes were 602 (group B). The mean age of the group A was significantly higher (30.1 + 2.9 vs. 29.4 + 2.9, p = 0.01). Group A displayed lower AMH and AFC [with interquartile ranges (IQR); AMH 1.6 ng/ml (1-2.6) vs. 3.5 ng/ml (2.2-5.4) p < 0.01, AFC 8 (6-12) vs. 12 (9-17), p < 0.01]. The number of small antral follicles (2-5 mm) of the group A was significantly lower [6 (4-8) vs. 8 (6-12) p < 0.01), while the larger follicles (5-10 mm) remained similar [3 (1-5) vs. 3(1-6) p = 0.3] between the groups. CONCLUSION: The propensity of low ovarian reserve and higher age are the main risk factors for the impaired ovarian response. The proportion of the small antral follicles may be a predictive factor for ovarian response to prevent unexpected poor results.

The viability of sperm is a crucial factor for achieving a successful pregnancy in intracytoplasmic sperm injection (ICSI) cycles. The aim of this study was to evaluate the accuracy of the hypo-osmotic swelling test (HOST) in fresh and frozen-thawed sperm samples of different origins (ejaculated/testicular). A retrospective analysis was conducted on the outcomes of 2167 oocytes subjected to ICSI using motile and immotile-HOST-positive sperm from 2011 to 2023. We evaluated embryonic development, as well as clinical, obstetric, and neonatal outcomes in four groups based on different sperm origins (ejaculated/testicular) and processing (fresh/frozen). When comparing the results of ICSI between motile and immotile-HOST-positive sperm within each group, it was observed that there were no significant differences in the outcomes for fresh samples. However, for frozen-thawed samples, fertilization rates and blastocyst development rates were significantly lower when ICSI was performed with immotile-HOST-positive sperm compared to motile sperm. Of note, clinical, obstetric, and neonatal outcomes were statistically similar across all groups. Our findings indicate that HOST is more reliable in fresh samples than in those subjected to the freeze-thaw process. Nonetheless, HOST is considered a safe method for selecting viable sperm in all subgroups.

Clinical and histopathological evidence suggest that the male reproductive system may be negatively impacted in patients with coronavirus disease (COVID-19). The objective of this study is to investigate the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on semen parameters by comparing semen analyses before and after COVID-19 diagnosis in the same patient. We retrospectively analyzed 342 semen analyses by reviewing medical records. The study included two groups of patients: (i) those who underwent two consecutive semen analyses within 6 months, one before (n = 114) and one after (n = 114) COVID-19 diagnosis, and (ii) a control group (n = 114) that was age-matched and did not receive a diagnosis of COVID-19. The study results indicated a significant decrease in semen volume, total sperm count per ejaculate, progressive motile sperm count, total motile sperm count, and normal sperm morphology after SARS-CoV-2 infection in comparison to their respective values before the infection. Subgroup analyses showed that the duration of COVID-19 diagnosis (short-term vs. long-term) did not impact the changes in semen parameters. However, fever during the COVID-19 process had a negative effect on semen parameters, particularly sperm concentration, unlike in patients without fever. In conclusion, our findings suggest that SARS-CoV-2 infection is associated with a decline in semen quality, which may potentially impact male fertility. Furthermore, it's important to note that the negative effects on semen parameters may persist in the long-term. Our results also indicate that fever during active infection could be a significant risk factor that negatively affects spermatogenesis.

This study investigates the triple combination of adjuvants (low molecular weight heparin (LMWH)-aspirin-prednisolone) whether it improves the live birth rates of IVF&ICSI patients with previous implantation failure. This retrospective study included 1095 patients with >2 failed either fresh or frozen single embryo transfer cycles between 2014 Jan and 2021 Jan. Patients were divided into two subgroups. Group A consisted of patients with only vaginal progesterone for luteal phase support. Group B consisted of patients with triple (daily subcutaneous LMWH, daily 150 mg aspirin, and daily 16 mg prednisolone) luteal phase supplementation to vaginal progesterone. Demographic parameters, cycle characteristics, embryology, and pregnancy outcomes were compared, and the study's primary outcome was the live birth rate. Demographic parameters were similar between the groups. Positive b-hCG, miscarriage, and live birth rates were similar between groups as Group A vs. Group B, positive b-hCG 30.8% (190/617) vs. 35.4% (169/478), miscarriage rates 4.4% (27/617) vs. 6.7% (32/478), and live birth rates 20.4% (126/617) vs. 23.8% (114/478), respectively. When patients were stratified according to previous failures, live birth rates were still similar. Pregnancy outcomes were significantly improved in only patients with diminished ovarian reserve (Group A vs. Group B, positive b-hCG 24.2% vs. 34.3%, live birth rate 12.1% vs. 21.9%, p < 0.01). Whether the embryo transfer was fresh or frozen-thawed did not affect the results. A combined supplementation of LMWH, aspirin, and prednisolone in the luteal phase does not improve live birth rates of IVF&ICSI patients with previous implantation failure except potentially for patients with diminished ovarian reserve.

OBJECTIVE: To assess the effect of the enhanced recovery after surgery (ERAS) protocol for cesarean deliveries (CD) on postoperative outcomes. METHODS: This multicenter prospective cohort study was conducted in six different centers between September 2020 and March 2021 and involved women who underwent either planned or unplanned CD. The primary outcome was time to the first passage of flatus following CD. Secondary outcomes included postoperative pain score, postoperative complications, and patient satisfaction. The protocol included early postoperative oral intake of ice cream and coffee, multimodal analgesia, antiemetic medications, and early ambulation. RESULTS: A total of 448 patients were included. The median time to the first passage of flatus was 10 h in the Hermes group and 18 hours in the control group (P < 0.001). Postoperative visual analog scale scores were significantly higher in the control group. Patient satisfaction scores and the frequency of postoperative complications did not differ between the groups (P = 0.08, P = 0.604, respectively). CONCLUSIONS: The ERAS protocol, including early serving of ice cream and coffee in the early postoperative period, enabled early discharge and a faster return of bowel function. Implementation of the ERAS protocol for patients who underwent planned and unplanned CD appeared to be safe and effective.

The aim of this study was to determine whether Kisspeptin and Kisspeptin receptor in the follicular microenvironment is necessary for human oocyte maturation and fertilisation. The cumulus cell (CC) and follicle fluids (FF) obtained from the first aspirated follicles (n = 52) from 32 patients were divided into three groups considering nuclear maturation and fertilisation results of oocytes: (1) Metaphase I or germinal vesicle stage oocytes (incomplete nuclear maturation, n = 10), (2) unfertilised metaphase II oocytes (incomplete cytoplasmic maturation, n = 16), and (3) fertilised metaphase II oocytes (completed nuclear-cytoplasmic maturation, n = 26). The gene expression levels were assessed by RT-PCR. The levels of Kisspeptin (KISS1) and Kisspeptin receptor (KISS1R) were measured by ELISA. There were no significant efficacy KISS1 and KISS1R gene expressions in cumulus cells in terms of oocyte nuclear maturation stage (Group 1, vs Group 2 + Group 3) (respectively p = .49; p = .45). In terms of the cytoplasmic maturation stage (Group 2, vs Group 3); KISS1 and KISS1R expressions in CCs were comparable (respectively p = .07; p = .08). In FFs, KISS1 and KISS1R concentrations were similar between all groups (respectively p = .86; p = .26). In conclusion, the relative KISS1 and KISS1R expressions in CC and also KISS1 and KISS1R level of FF were independent of oocytes nuclear and/or cytoplasmic maturation. Impact statementWhat is already known on this subject? It has been demonstrated that Kisspeptin is an essential regulator of reproductive function and plays a key role in the modulation of GnRH secretion and gonadotropin release. Still, no information is available about the link between gene expression or concentration in the follicular microenvironment and oocyte development.What do the results of this study add? The study has shown that the relative Kisspeptin (KISS1) and Kisspeptin receptor (KISS1R) and expressions in cumulus cell (CC) and also KISS1 and KISS1R levels of follicle fluids (FF) were independent of oocytes nuclear and/or cytoplasmic maturation.What are the implications of these findings for clinical practice and/or further research? Based on the findings, it is difficult to establish a concept that kisspeptin can directly induce oocyte maturation. Nevertheless, to confirm these findings, further studies with a larger sample size are needed.

OBJECTIVE: To investigate whether the frequency of uterine cavity abnormalities in PCOS patients higher than the normo-ovulatory patients. STUDY DESIGN: This retrospective cohort study was conducted at the ART center of a tertiary university hospital. A total of 103 patients; 51 PCOS, and 52 male factor infertility were enrolled in the study between the years 2011-2019. HSG images of all patients were numbered and evaluated by ten senior reproductive endocrinologists and surgeons whom were blinded to the research and choose the most appropriate figure for each patient's HSG image and marked the shape of cavity according to the ASRM and ESGE/ESHRE classification. Results and demographic parameters were compared between PCOS and male factor infertility groups. RESULTS: The percentage of the normal uterine cavity was significantly lower in the PCOS group than control group as 51 % and 66.7 %, 77 % and 94.2 % according to the ASRM and ESHRE/ESGE classifications, respectively. The frequency of Partial Septate Uterus (ESHRE-ESGE U2a / ASRM Va, 21.6% vs 5.8 % p < 0.05), Complete Septate Uterus (ESHRE-ESGE U2b / ASRM Vb, 7.8% vs 0% p < 0.01) and Dysmorphic Uterus (ESHRE-ESGE U1c) / ASRM VII) 3.9 % vs 0p < 0.05) were significantly higher in PCOS patients than controls. The frequency of arcuate uterus classified as VI in ASRM and considered as normal in ESHRE/ESGE was 16 % and 17.3 % in PCOS and control groups, respectively, without statistically significant difference. CONCLUSIONS: This study provides that, compared to the healthy population, the frequency of uterine cavity abnormality is clearly higher in PCOS patients.

This retrospective study aims to determine the more predictive ovarian reserve marker when there is discordance between anti-Müllerian hormone (AMH) and antral follicle count (AFC) in patients with diminished ovarian reserve (DOR). Patients who underwent ICSI because of DOR were divided into three groups. Group 1: patients with low AMH (<1.1 ng/ml) and AFC (n < 7), group 2: patients with low AMH (<1.1 ng/ml) and normal AFC (n ≥ 7) and group 3: patients with normal AMH (≥1.1 ng/dl) and low AFC (n < 7). Demographic values, follicle output rate (FORT) score and follicle to oocyte index (FOI) score of the groups were compared. Totally, 662 cycles were enrolled in the study. There were 418 cycles in group 1, 167 cycles in group 2 and 77 cycles in group 3. As the primary result, FORT and FOI scores were higher in group 3 than the other two groups. Median FORT Score with quartiles: group 1: 100 (66-150), group 2: 71 (57-100), group 3: 136 (96-200), p<.01 - median FOI score with quartiles: group 1: 83 (50-140), group 2: 71 (40-100), group 3: 116 (66-216), p<.01. In conclusion, serum AMH level has more predictive value for stimulation success if there is discordance with AFC.Impact StatementWhat is already known on this subject? Female age, serum Anti-Müllerian Hormone (AMH) levels, and antral follicle count (AFC) are commonly used to assess ovarian reserve and predict response to ovarian stimulation. AMH and AFC are both positively correlated with ovarian reserve.What do the results of this study add? If there is discordance between AFC and AMH in patients with diminished ovarian reserve (DOR), the ovarian response is better in patients with high AMH and low AFC than the patients with low AMH and high AFC.What are the implications of these findings for clinical practice and/or further research? It is important to assess both AFC and AMH before controlled ovarian hyperstimulation, to predict ovarian response in DOR patients, rather than assessing AFC or AMH alone.

The objective of this study was to assess the effect of rescue in vitro maturation and immediate intracytoplasmic sperm injection (ICSI) application on fertilisation success and early embryonic development of metaphase I (MI) oocytes. This was a retrospective cohort study including 2425 sibling oocytes in 259 ICSI cycles. ICSI was performed on 104 GV (germinal vesicle) oocytes which had reached the metaphase II (MII) stage (Group 1) and 231 MI oocytes which had reached the MII stage (Group 2) following IVM (in vitro maturation). Immediate ICSI was applied following oocyte aspiration on 292 MI stage (Group 3) and 1798 MII stage oocytes (Group 4). Normal fertilisation rates in Groups 1, 2, 3 and 4 were 51.9%, 39%, 30.1% and 59.5%, respectively. The rates of blastocyst development per oocyte and per zygote were calculated as 3.8%, 3.0%, 6.8%, 14.1% and 7.4%, 7.7%, 22.7%, 23.6% for Groups 1, 2, 3 and 4, respectively. The blastocyst development rate was significantly higher in the MI-ICSI group compared with other immature oocytes. Even though performing ICSI on the oocytes at the MI stage on the day of oocyte aspiration resulted in lower fertilisation rates, it was associated with significantly higher rates of blastocyst development.

The aim of this study was to evaluate whether antral follicle size has any value with respect to antral follicle count (AFC) in predicting ovarian response to controlled ovarian stimulation. Patients who were considered to be normal responders based on their ovarian reserve markers were consecutively recruited. Total AFC was the number of 2-10 mm follicles in both ovaries. Antral follicles were separated into two subgroups according to the size: 2-5 mm and 6-10 mm follicles. Patients were divided into two main groups according to ovarian response to COS. Group 1 (suboptimal response, 4-9 oocytes retrieved, n = 61) and Group 2 (normal responders, ≥10 oocytes retrieved, n = 65). Demographic parameters were comparable between the groups. The number of 2-5 mm follicles was significantly lower in the suboptimal response group (5 [4:7] and 8 [6:10], respectively, p < .001). The ratio of 2-5 mm follicles to total antral follicles was also significantly lower in Group 1 (44.4% and 75%, respectively, p < .001). The ratio of small antral follicles was positively correlated with ovarian response (r = 0.587, p < .001). In conclusion, the ratio of small (2-5 mm) antral follicles could be a more specific predictive marker than AFC for ovarian response.IMPACT STATEMENTWhat is already known on this subject? Prediction of the ovarian response during ovarian stimulation is commonly based on antral follicle count and anti-mullerian hormone. The ovarian response may be inadequate even in patients with normal antral follicle count and anti-mullerian hormone.What do the results of this study add? A high ratio of small-size (2-5 mm) basal antral follicles is a predictive factor for higher ovarian response to ovarian hyperstimulation.What are the implications of these findings for clinical practice and/or further research? To obtain optimal ovarian response, the antral follicles should be evaluated initially in a more detailed and systematic way by taking their sizes into consideration in addition to their counts. Small antral follicle count rather than whole antral follicle count may be beneficial for optimising the ovarian response. Future studies may determine the cut off values of small antral follicle count for high/poor ovarian response.

OBJECTIVE: To determine the predictive value of cryopreserved embryos during single fresh blastocyst transfer. METHODS: This retrospective cohort study was conducted at a tertiary university hospital ART center. Patients who underwent a single fresh blastocyst transfer were selected from the electronic database. Patients with diminished ovarian reserve, uterine pathology, advanced age (>40 years) were excluded from the study. Patients were divided into two groups. Group A consisted of patients with only one available embryo for the fresh transfer. Group B consisted of patients with cryopreserved embryos apart from the fresh transferred embryo. Demographic and embryology parameters, pregnancy results were compared. RESULTS: Demographic values, ovarian reserve parameters were comparable between groups. The number of the picked-up oocyte, metaphase-2 oocyte, and two-pronucleus embryo was lower in Group A. Positive pregnancy rates were two-fold higher in Group B (23.4% vs. 50.9% p < .01). Pregnancy results did not change depending on the number of cryopreserved embryos in Group B. CONCLUSION: According to our results, the presence of cryopreserved embryos results in higher pregnancy rates in patients with fresh blastocyst embryo transfer independent from the woman's age and ovarian reserve. Thus, these results may help us to predict the implantation rate before embryo transfer.

Although the efficiency of progesterone in providing luteal phase support has been established, the role of oestradiol supplementation during the luteal phase remains controversial. We evaluated pregnancy outcomes of patients who had a ratio of serum E2 levels on the hCG day to the number of oocytes retrieved (oestradiol/oocyte ratio - EOR) levels of <100 pg/ml by supporting them with additional oestradiol during the luteal phase. In total, 150 patients with an EOR < 100 pg/ml of oestradiol undergoing antagonist intracytoplasmic sperm injection (ICSI) cycles were randomly assigned into two groups to receive either oral oestradiol (4 mg/d) plus vaginal progesterone (90 mg, 2 × 1/day) (group 1) or vaginal progesterone (90 mg, 2 × 1/d) alone (group 2). Implantation rate following transfer of a single embryo did not differ between the two groups (group 1 = 33.3%; group 2 = 34.9%; p = 0.85). Similarly, both groups gave comparable clinical pregnancy rates per embryo transfer with 31.7% in group 1 compared with 28.6% in group 2 (p = 0.69). In conclusion the study suggests that the addition of 4 mg oral E2 to progesterone does not increase the probability of pregnancy.

OBJECTIVES: This study aims to investigate the effects of transcutaneous electrical nerve stimulation (TENS) therapy on the intensity of pain associated with uterine contractions and abdominal incision in patients undergoing cesarean section (C-section) delivery. PATIENTS AND METHODS: This single-blind, prospective, randomized-controlled study included a total of 90 female patients (mean age 30.5 years; range, 25 to 36 years) who had a scheduled C-section delivery between November 2017 and April 2018. Forty-five postpartum patients were randomly assigned into the treatment group (Group 1) and TENS electrodes were placed below and above the abdominal incision. The control group (n=45) consisted of 45 patients who had a scheduled C-section (Group 2) (n=45) and received routine follow-up care. The Visual Numeric Scale (VNS) scores were obtained separately for abdominal, low back, and groin pain at baseline (within 1 h after C-section before the TENS replacement), at postpartum 2, 6, 24, and 48 h. In addition to instant scoring, the percentages of change in pain scores from baseline were also calculated for each time points. RESULTS: Data of a total of 87 patients were analyzed. No statistically significant difference was found in the baseline VNS scores measured in any body regions between the groups (p>0.05). However, there was a statistically significant difference in the instant VNS scores for abdominal pain at 2, 6, 24, and 48 h in favor of Group 1 (p<0.05). No significant differences were found in the instant VNS scores for low back and groin pain (p>0.05). The comparison of changes in pain scores from baseline (% change) over time between the groups revealed a statistically significant difference in favor of Group 1 in all VNS scores for abdominal, low back, and groin pain at 2, 6, 24, and 48 h (p<0.05). CONCLUSION: Our study results suggest that TENS is an effective and safe non-invasive, non-pharmacological treatment modality. It may be preferred as an alternative method in pain control in postpartum women after C-section delivery.
RESUMEN
OBJECTIVE: There has been a heated discussion about mesh materials in urogynecology in recent years. The role of social media in this discussion is critical. This study aims to make a systematic analysis of videos uploaded to YouTube about mesh complications in urogynecology. STUDY DESIGN: YouTube was searched using specific terms about mesh materials. The primary outcome was the relationship between the video characteristics -which were publisher identity, attitude, the main focus of the video country, and year- and the mesh debate in urogynecology. RESULTS: We analyzed 1128 YouTube videos about mesh complications. There was no distinction between stress urinary incontinence and pelvic organ prolapse when referring to the mesh material in 79 % of the videos. 35.2 % of the videos were in the News group, 31.2 % were in the Patients group, 19.6 % were in the Doctors group, and 14.0 % were in the Lawyers group. Videos in the News (75.7 %), Patients (92.6 %), and Lawyers (99.4 %) groups mostly had a negative attitude, while videos in the Doctors (48.9 %) group mostly had an informative attitude. News (43.2 %) and Patients (51.2 %) group videos were predominantly from the United Kingdom. However, Lawyers (81.0 %) and Doctors (44.3 %) videos were predominantly from the USA. In the last three years, the news and patients videos have increased by an average of 40 % each year. CONCLUSION: YouTube has influenced the mesh dilemma with a negative attitude. As long as social media is at the center of this discussion, a healthy outcome cannot be achieved.
