hMG addition affects the change in progesterone level during IVF stimulation and LBR: a retrospective cohort study.

BACKGROUND: Premature progesterone (P) rise during IVF stimulation reduces endometrial receptivity and is associated with lower pregnancy rates following embryo transfer (ET), which can influence provider recommendation for fresh or frozen ET. This study aimed to determine whether change in P level between in IVF baseline and trigger (𝚫P) is predictive of pregnancy outcome following fresh ET, and whether the ratio of gonadotropins influences P rise and, as a result, clinical pregnancy outcomes: clinical pregnancy rate (CPR) and live birth rates (LBR). METHODS: Retrospective cohort study at a single fertility center at an academic institution. The peak P level and 𝚫P were modeled in relation to prediction of CPR and LBR, and the ratios of hMG:rFSH were also modeled in relation to prediction of peak P level on day of trigger, 𝚫P, and CPR/LBR in a total of 291 patients undergoing fresh embryo transfer after controlled ovarian hyperstimulation-IVF (COH-IVF). RESULTS: 𝚫P correlates with CPR, with the most predictive range for success as 𝚫P 0.7-0.85 ng/mL (p = 0.005, 95% CI 0.635, 3.636; predicting CPR of 88.9%). The optimal range for peak P in regard to pregnancy outcome was 0.15-1.349 ng/mL (p = 0.01; 95% CI for coefficient in model 0.48-3.570). A multivariable logistic model for prediction of CPR and LBR using either peak or 𝚫P supported a stronger association between 𝚫P and CPR/LBR as compared to peak P. Furthermore, an hMG:rFSH ratio of > 0.6 was predictive of lowest peak P (p = 0.010, 95% CI 0.035, 0.256) and smallest 𝚫P (p = 0.012, 95% CI 0.030, 0.243) during COH-IVF cycles. Highest CPRs were observed within hMG:rFSH ratios of 0.3-0.4 [75.6% vs. 62.5% within and outside of the range, respectively, (p = 0.023, 95% CI 0.119, 1.618)]. Highest LBRs were seen within the range of 0.3-0.6 hMG:rFSH, [LBR of 55.4% vs. 41.4% (p = 0.010, 95% CI 0.176, 1.311)]. CONCLUSIONS: Our data supports use of 𝚫P to best predict pregnancy rates and therefore can improve clinical decision making as to when fresh ET is most appropriate. Furthermore, we found optimal gonadotropin ratios can be considered to minimize P rise and to optimize CPR/LBR, emphasizing the importance of luteinizing hormone (LH) activity in COH-IVF cycles.

Intraovarian Platelet-rich Plasma Administration Induced Spontaneous Ovulation in an Anovulatory Woman With PCOS.

The use of platelet-rich plasma (PRP) has become popular as an adjunct to fertility treatment for women with infertility, particularly those with low ovarian reserve and premature ovarian insufficiency. Recent data in a polycystic ovary syndrome (PCOS) animal model demonstrated that intraovarian PRP administration improved folliculogenesis, ovarian antioxidant potential, and serum hormonal imbalance, suggesting that PRP could be considered a novel technique to alleviate PCOS-induced pathogenesis. With injection of PRP into the ovaries, it has been hypothesized that the infusion of cytokines and growth factors may exhibit a local effect that changes the expression of genes important in folliculogenesis and steroidogenesis, decreases inflammation, and partially restores normal ovarian function. This report is the first to present a case of a long-term amenorrheic woman with PCOS who has been trying to conceive, who resumed spontaneous ovulatory cycles, and had improvement in several aspects of her hormonal imbalance following intraovarian PRP administration. The purpose of this case report is to increase awareness regarding the possible benefits of intraovarian PRP injections for women with PCOS. There is a clear need for larger prospective studies to properly elucidate the effect of intraovarian PRP administration on both the reproductive and metabolic dysfunctions observed in women with PCOS.

Role of video self-assessment in laparoscopic simulation training: a randomized pilot trial.

BACKGROUND: Residency programs have implemented simulation training to compensate for reduced operating room exposure. Video recording is an educational tool that can be utilized for coaching, telepresence, and self-assessment during simulation training. Data is limited on the utility of video recording and self-assessment for laparoscopic training in Ob/Gyn residency programs.. OBJECTIVE: This study aimed to determine the role of video self-assessment as an educational tool in laparoscopic simulation training and to establish the feasibility of our study design for a larger randomized controlled trial. STUDY DESIGN: This was a prospective pilot study with a parallel, randomized, trial design that occurred in the Department of Obstetrics and Gynecology at the Mount Sinai Hospital. Subject participation took place in a surgical simulation training room. A total of 23 subjects were recruited (7 medical students, 15 residents, 1 fellow) voluntarily. All participants completed the study. All the subjects completed a pretest survey. The surgical simulation room contained a single Fundamentals of Laparoscopic Surgery box trainer and video-recording station. For session #1, each participant performed 2 Fundamentals of Laparoscopic Surgery tasks (A, peg transfer; B, intracorporeal knot tie). Participants were video recorded during session #1 and were randomized to either receive or not receive their video recording. The video group (n=13) and control group (n=10) repeated the Fundamentals of Laparoscopic Surgery tasks 7 to 10 days later (session #2). The primary outcome was percentage change in completion time between sessions. Secondary outcomes were percentage change in peg and needle drops between sessions. RESULTS: The participant characteristics (video vs control) were as follows: average training level (6.15 vs 4.90 years), self-assessment (1=poor, 10=excellent) of surgical skill (4.8 vs 3.7), and laparoscopic skill (4.4 vs 3.5). Training level was inversely correlated with completion time for tasks A and B (r, -0.79 and -0.87; P<.0001). Less experienced trainees required the maximum time allotted for each task in session #1 (A, 3; B, 13). Regarding the primary outcome, the video group improved less than the control group (A, 16.7% vs 28.3%; B, 14.4% vs 17.3%). After controlling for training level (residents only), the video group improved more in the primary outcome (A, 17% vs 7.4%; B, 20.9% vs 16.5%) and secondary outcomes (A, 0.0% vs -194.1%; B, 41.3% vs 37.6%). CONCLUSION: Video self-assessment has a potential role in simulation training for obstetrics-gynecology residents. With key improvements, the feasibility of our study design was demonstrated in preparation for a future definitive trial.

Does PGT-A affect cumulative live birth rate?

PURPOSE OF REVIEW: Preimplantation genetic testing for the purpose of aneuploidy screening (PGT-A) has increased in use over the last decade. RECENT FINDINGS: Whether PGT-A benefits all of the patients that choose to employ it has been a concern, as recent studies have highlighted a potential decrease in cumulative live birth rate (CLBR) for younger patients undergoing embryo transfer. However, there are limitations to many of these studies and the intended benefit of PGT-A, which is to aid as a selection tool, thus increasing the live birth rate per transfer, must not be ignored. SUMMARY: PGT-A was never intended to increase CLBR. The purpose of PGT-A is to maximize the chance at live birth per transfer while minimizing the risk of clinical miscarriage, ongoing aneuploid pregnancy and futile transfers. However, if it harms CLBR in the process that has to be taken into consideration. This review will discuss PGT-A in terms of its benefits, risks, and how it has been shown to affect the cumulative live birth rate within in-vitro fertilization cycles.

Intraovarian platelet-rich plasma administration could improve blastocyst euploidy rates in women undergoing in vitro fertilization.

OBJECTIVE: Platelet-rich plasma (PRP) therapy has received a considerable attention as an adjunct to fertility treatments, especially in women with very low ovarian reserve and premature ovarian insufficiency. Although recent studies have demonstrated that PRP led to improvements in folliculogenesis and biomarkers of ovarian reserve, the effect of intraovarian PRP administration on embryo genetics has not been studied. METHODS: We report a pilot study of patients who had preimplantation genetic testing for aneuploidy (PGT-A) before and then within 3 months following PRP administration. Twelve infertile women with at least one prior failed in vitro fertilization (IVF) cycle underwent ovarian stimulation (cycle 1) with a gentle stimulation protocol and PGT-A performed at the blastocyst stage. Following cycle 1, autologous intraovarian PRP administration was performed. Within 3 months following PRP administration, the patients underwent cycle 2 and produced blastocysts for PGT-A. The percentage of euploid embryos between both cycles was compared. RESULTS: The mean age of all participants was 40.08±1.46 years, and their mean body mass index was 26.18±1.18 kg/m2. The number of good-quality embryos formed at the blastocyst stage was similar between cycle 1 and cycle 2 (3.08±0.88 vs. 2.17±0.49, respectively; p=0.11). Among all patients in cycle 1, 3 of 37 embryos were euploid (8.11%) while in cycle 2, 11 out of 28 embryos were euploid (39.28%, p=0.002). Three clinical pregnancies were noted among this patient group. CONCLUSION: This novel study is the first to present an improvement in the embryo euploidy rate following intraovarian PRP application in infertile women with prior failed IVF cycles. The growth factors present in PRP may exhibit a local paracrine effect that could improve meiotic aberrations in human oocytes and thus improve euploidy rates. Whether PRP improves live birth rates and lowers miscarriage rates remains to be determined in large trials.

A Case of Asthenozoospermia Following COVID-19 Infection.

PURPOSE: Studies pertaining to the effect of COVID-19 infection on male fertility are scarce. This case report describes a case of transient asthenozoospermia, absence of sperm motility, following a moderately severe COVID-19 infection. CASE: A couple presenting for infertility treatment due to low ovarian reserve presented for their second intrauterine insemination (IUI). Their first IUI was performed 1 month earlier when the semen parameters were normal. A couple of weeks before the second IUI, the unvaccinated 48-year-old male partner contracted COVID-19 and was admitted to the hospital for several days. He received IV Remdesivir and continuous oxygen by nasal cannula. His hospitalization did not require intubation or intensive care unit admission. He was discharged after 12 days of hospitalization without home oxygen treatment. On the day of the second IUI, the semen analysis showed a normal sperm count with 0% motility. Three months following his COVID-19 diagnosis, a repeat semen analysis showed restored normal parameters with more than 40% motility. CONCLUSION: This aim of this report is to increase awareness that moderate COVID-19 requiring hospitalization could affect, though temporarily, sperm motility and should be considered in the differential diagnosis when male infertility is encountered.

Isthmocele endometriosis: the relationship between cesarean section and endometriosis.

OBJECTIVE: To present a case of endometriosis within an isthmocele membrane and concomitant diffuse peritoneal endometriosis after cesarean sections. In addition, we describe a unique, color-contrasted surgical repair technique and propose a possible correlation between isthmocele formation and endometriosis. DESIGN: Narrated video article featuring the diagnosis, unique surgical management, and pathological findings of a case of isthmocele endometriosis. Informed consent was obtained from the patient, and all identifiers were removed. SETTING: University-affiliated hospital. PATIENT(S): A 44-year-old patient with three prior cesarean sections and a laparoscopic appendectomy, in none of which endometriosis was visualized. She presented with progressive pelvic pain, dysmenorrhea, dyspareunia, and secondary infertility with recurrent embryo transfer failures. The progressively debilitating symptoms started 14 years ago, shortly after her last cesarean section. Magnetic resonance imaging and ultrasound demonstrated a retroverted uterus and a prominent, thin, fluid-filled cesarean scar defect with a residual myometrial thickness of 1.1 mm. INTERVENTION(S): A combined hysteroscopic and laparoscopic approach was performed to allow for complete resection of the defect and reconstruction of the myometrium. The bladder was backfilled with indocyanine green dye to help identify its borders. Methylene blue was added to the hysteroscopy irrigation solution to create contrast and assist with the isthmocele identification. Wide excision of the isthmocele was performed, followed by a three-layer closure and excision of all apparent peritoneal lesions using the Aqua Blue Contrast Technique. MAIN OUTCOME MEASURE(S): Restoration of normal anatomy, resection of isthmocele, and resolution of the symptoms. RESULT(S): In the pathological assessment, multiple foci of endometriosis were identified within the isthmocele membrane, clearly differentiated from intrauterine endometrial tissue. Additionally, all seven excised peritoneal specimens contained peritoneal endometriosis. Two weeks after the procedure, a transvaginal sonographic scan confirmed a thick anterior uterine wall with a myometrial thickness of 9.2 mm, and the patient reported almost complete resolution of her symptoms. CONCLUSION(S): This case demonstrates endometriosis within the isthmocele membrane, with concomitant symptomatic peritoneal endometriosis. We propose a laparoscopic isthmocele excision technique and a three-layer reconstruction, followed by peritoneal endometriosis excision using methylene blue contrast. We suggest a possible link between isthmocele and endometriosis and emphasize the need for wide excision of the isthmocele margins and maintaining clean borders, given the possibility of endometriosis within the isthmocele, which may be a cause or a contributor to the tissue weakness and isthmocele formation.

Ovarian response to intraovarian platelet-rich plasma (PRP) administration: hypotheses and potential mechanisms of action.

PURPOSE: Platelet-rich plasma (PRP) therapy has been used as an adjunct to fertility treatments in women with very low ovarian reserve and premature ovarian insufficiency. Recent literature in both humans and animals suggest that intraovarian PRP administration in the setting of poor ovarian reserve may help ovarian function and increase the chances of pregnancy. METHODS: A comprehensive literature search through PubMed, MEDLINE databases, and recent abstracts published at relevant society meetings was performed and resulted in 25 articles and 2 abstracts published that studied effect of PRP on the ovaries for the purpose of reproduction. RESULTS: This review article presents all the data published to date pertaining to intraovarian PRP injection and pregnancy, both naturally and after in vitro fertilization. It also presents the most recent data on the use of ovarian PRP in in vitro and animal model studies highlighting the possible mechanisms by which PRP could impact ovarian function. CONCLUSIONS: Even though recent commentaries questioned the use of PRP as an "add-on" therapy in fertility treatment because it has not been thoroughly studied, the recent basic science studies presented here could increase awareness for considering more serious research into the efficacy of PRP as an adjunct for women with poor ovarian reserve, premature ovarian insufficiency, and even early menopause who are trying to conceive using their own oocytes. Given its low-risk profile, the hypothetical benefit of PRP treatment needs to be studied with larger randomized controlled trials.

Intraovarian PRP Injection Improved Hot Flashes in a Woman With Very Low Ovarian Reserve.

PRP, rich in growth factors and cytokines, has been gaining considerable attention as an adjunct therapy to fertility treatment for women with very low ovarian reserve and premature ovarian insufficiency. To date, most prior studies have focused on the effect of PRP on ovarian response pertaining to oocyte production and pregnancy outcome following assisted reproductive technology. This report presents a patient with very low ovarian reserve, with medical problems that preclude her from taking hormone replacement therapy, who presented for fertility treatment with PRP and then accidentally reported significant improvement of menopausal symptoms including her hot flashes for 14 weeks following PRP intra-ovarian injection. The purpose of this case report is to increase awareness of clinicians about the use of PRP as a potential alternative therapy for hot flashes in women who have contraindications for hormone replacement therapy.

Use of Intra-uterine Injection of Platelet-rich Plasma (PRP) for Endometrial Receptivity and Thickness: a Literature Review of the Mechanisms of Action.

Endometrial receptivity and thickness play an important role in achieving a pregnancy. Intrauterine autologous platelet-rich plasma (PRP) infusion has been used in infertile women with recurrent implantation failure (RIF) and thin endometrial lining thickness (EMT). Literature search was performed in PubMed for studies including in vitro, animal, and human studies as well as in abstracts presented at national conferences. Animal studies demonstrated a decrease in the expression of inflammatory markers and fibrosis, and increased endometrial proliferation rate, increased expression of proliferative genes, and increased pregnancy rates. The in vitro studies showed that PRP was associated with increased stromal and mesenchymal cell proliferation, increased expression of regenerative enzymes, and enhancement in cell migration. In infertile women undergoing assisted reproductive technology, one randomized clinical trial showed that PRP intrauterine infusion improved EMT, implantation rate, and clinical pregnancy rate (CPR) in patients with thin EMT, while 3 other trials involving subjects with RIF showed conflicting results related to CPR. Case series and cohort studies showed conflicting results pertaining to CPR. Data to date suggest that PRP may be beneficial in improving endometrial thickness and endometrial receptivity. However, further large prospective and high-quality trials are needed to assert its effect and to identify the population of patients that would benefit the most.

Naringenin inhibits neointimal hyperplasia following arterial reconstruction with interpositional vein graft.

Vessels respond to injury by a healing process that includes the development of neointima. Stenosis secondary to neointima formation is the main cause of failure following arterial reconstructions. Vessel wall homeostasis is regulated by proinflammatory cytokines that affect smooth muscle cell proliferation, growth, migration, and death. We assessed the hypothesis that naringenin, a flavinoid possessing anti-inflammatory, antioxidant, and antiproliferative activities, reduces neointimal hyperplasia (NIH) following vascular injury.Arterial injury was created by interposition grafting of autologous right superficial epigastric vein graft into the right femoral artery (FA) in 48 male Sprague-Dawley rats. Following injury, the rats were divided into 4 groups (n = 12). Two groups were treated with naringenin (100 mg/kg intraperitoneal q daily) for 2 and 4 weeks each while 2 control groups received normal saline for the same durations. For Sham group (n = 10), the FA and vein were isolated without any additional procedure. Rats were killed at the end of treatment regimen in all groups, and FAs were harvested. Thickness of intima was measured in histologic sections, and levels of platelet derived growth factor (PDGF)-BB, TNFalpha, and Ki67 labeling index (Ki67 LI) were quantified in immunohistochemical analyses to assess the amount of NIH and mechanisms underlying its formation.Although there was no significant difference between the groups at 2 weeks, neointima thickness was lower in the naringenin treated group at 4 weeks (23.7 +/- 2.3 vs. 35.6 +/- 2.6 microm in control group; P < 0.001). The levels of PDGF-BB, and TNFalpha were lower in naringenin treated groups at both 2 weeks (PDGF-BB [0.21% +/- 0.03% versus 0.39% +/- 0.05% in control group, P < 0.001), TNFalpha (21.2% +/- 0.8% vs. 36.1% +/- 1.9% in control group, P < 0.001]) and 4 weeks (PDGF-BB [0.25% +/- 0.03% vs. 0.57% +/- 0.09% in control group, P < 0.001], TNFalpha [25.5% +/- 1.8% vs. 45.0% +/- 2.9% in control group, P < 0.001]). Ki67 LI was lower in naringenin treated groups at 2 weeks (13.9% +/- 2.8% vs. 18.7% +/- 3.7% in control group, P < 0.05), and at 4 weeks (17.5% +/- 2.6% vs. 31.1% +/- 4.7% in control group, P < 0.001), indicating a lower level of cellular proliferation.Naringenin reduces NIH following arterial reconstruction. This may be mediated by a decrease in PDGF-BB and TNFalpha levels and the resulting down-regulation of smooth muscle cells' migration and proliferation.
