Retrograde menstruation is a widely accepted cause of endometriosis. However, not all women who experience retrograde menstruation develop endometriosis, and the mechanisms underlying these observations are not yet understood. Here, we demonstrated a pathogenic role of in the formation of ovarian endometriosis. In a cohort of women, 64% of patients with endometriosis but <10% of controls were found to have infiltration in the endometrium. Immunohistochemical and biochemical analyses revealed that activated transforming growth factor-β (TGF-β) signaling resulting from infection of endometrial cells led to the transition from quiescent fibroblasts to transgelin (TAGLN)-positive myofibroblasts, which gained the ability to proliferate, adhere, and migrate in vitro. inoculation in a syngeneic mouse model of endometriosis resulted in a marked increase in TAGLN-positive myofibroblasts and increased number and weight of endometriotic lesions. Furthermore, antibiotic treatment largely prevented establishment of endometriosis and reduced the number and weight of established endometriotic lesions in the mouse model. Our data support a mechanism for the pathogenesis of endometriosis via infection and suggest that eradication of this bacterium could be an approach to treat endometriosis.

Review
Pelvic inflammatory disease (PID) is an infection of the upper genital tract occurring predominantly in sexually active young women. Chlamydia trachomatis and Neisseria gonorrhoeae are common causes; however, other cervical, enteric, bacterial vaginosis-associated, and respiratory pathogens, including Mycobacterium tuberculosis, may be involved. PID can be acute, chronic, or subclinical and is often underdiagnosed. Untreated PID can lead to chronic pelvic pain, infertility, ectopic pregnancy, and intra-abdominal infections. The diagnosis is made primarily on clinical suspicion, and empiric treatment is recommended in sexually active young women or women at risk for sexually transmitted infections who have unexplained lower abdominal or pelvic pain and cervical motion, uterine, or adnexal tenderness on examination. Mild to moderate disease can be treated in an outpatient setting with a single intramuscular injection of a recommended cephalosporin followed by oral doxycycline for 14 days. Additionally, metronidazole is recommended for 14 days in the setting of bacterial vaginosis, trichomoniasis, or recent uterine instrumentation. Hospitalization for parenteral antibiotics is recommended in patients who are pregnant or severely ill, in whom outpatient treatment has failed, those with tubo-ovarian abscess, or if surgical emergencies cannot be excluded. Treatment does not change in patients with intrauterine devices or those with HIV. Sex partner treatment is recommended; expedited partner treatment is recommended where legal. Prevention of PID includes screening for C. trachomatis and N. gonorrhoeae in all women younger than 25 years and those who are at risk or pregnant, plus intensive behavioral counseling for all adolescents and adults at increased risk of sexually transmitted infections.

Review
Pelvic inflammatory disease (PID) is an ascending polymicrobial infection of the upper female genital tract. The presentation of PID varies from asymptomatic cases to severe sepsis. The diagnosis of PID is often one of exclusion. Primary treatment for PID includes broad-spectrum antibiotics with coverage against gonorrhea, chlamydia, and common anaerobic and aerobic bacteria. If not clinically improved by antibiotics, percutaneous drain placement can promote efficient source control, as is often the case with large tubo-ovarian abscesses. Ultimately, even with treatment, PID can result in long-term morbidity, including chronic pelvic pain, infertility, and ectopic pregnancy.

Review
Abdominal pain is a common reason for emergency department visits, with many patients not receiving a definitive diagnosis for their symptoms. Non-gastrointestinal causes need to be considered in the workup of abdominal pain. A high index of suspicion is needed in order to develop a broad differential, and a thorough history and physical examination is paramount. This article will discuss some of these diagnoses, including can't miss diagnoses, common non-abdominal causes, and rare etiologies of abdominal pain.

Review
BACKGROUND
In 2020, SARS-CoV-2 and the COVID-19 pandemic had a huge impact on the access to and provision of ART treatments. Gradually, knowledge of the virus and its transmission has become available, allowing ART activities to resume. Still, questions on the impact of the virus on human gametes and fertility remain.
OBJECTIVE AND RATIONALE
This article summarizes published data, aiming to clarify the impact of SARS-CoV-2 and the COVID-19 disease on human fertility and assisted reproduction, as well as the impact of vaccination, and from this, provide answers to questions that are relevant for people contemplating pregnancy and for health care professionals.
SEARCH METHODS
PUBMED/MEDLINE and the WHO COVID-19 database were searched from inception to 5 October 2022 with search terms focusing on 'SARS-CoV-2' and gametes, embryos, reproductive function, fertility and ART. Non-English studies and papers published prior to 2020 were excluded, as well as reviews and non-peer reviewed publications. Full papers were assessed for relevance and quality, where feasible.
OUTCOMES
From the 148 papers included, the following observations were made. The SARS-CoV-2-binding proteins, angiotensin-converting enzyme 2 (ACE2) and type II transmembrane serine protease (TMPRSS2), are expressed in the testis, but co-expression remains to be proven. There is some evidence of SARS-CoV-2 RNA in the ejaculate of COVID-19 patients with severe disease, but not in those with mild/moderate disease. SARS-CoV-2 infection can impair spermatogenesis, but this seems to resolve after one spermatogenic cycle. Testosterone levels seem to be lower during and after COVID-19, but long-term data are lacking; disease severity may be associated with testosterone levels. COVID-19 cannot be considered a sexually transmitted disease. There is no co-expression of ACE2 and TMPRSS2 in the myometrium, uterus, ovaries or fallopian tubes. Oocytes seem to have the receptors and protease machinery to be susceptible to SARS-CoV-2 infection; however, viral RNA in oocytes has not been detected so far. Women contemplating pregnancy following COVID-19 may benefit from screening for thyroid dysfunction. There is a possible (transient) impact of COVID-19 on menstrual patterns. Embryos, and particularly late blastocysts, seem to have the machinery to be susceptible to SARS-CoV-2 infection. Most studies have not reported a significant impact of COVID-19 on ovarian reserve, ovarian function or follicular fluid parameters. Previous asymptomatic or mild SARS-CoV-2 infection in females does not seem to negatively affect laboratory and clinical outcomes of ART. There are no data on the minimum required interval, if any, between COVID-19 recovery and ART. There is no evidence of a negative effect of SARS-CoV-2 vaccination on semen parameters or spermatogenesis, ovarian function, ovarian reserve or folliculogenesis. A transient effect on the menstrual cycle has been documented. Despite concerns, cross reactivity between anti-SARS-CoV-2 spike protein antibodies and Syncytin-1, an essential protein in human implantation, is absent. There is no influence of mRNA SARS-CoV-2 vaccine on patients' performance during their immediate subsequent ART cycle. Pregnancy rates post-vaccination are similar to those in unvaccinated patients.
WIDER IMPLICATIONS
This review highlights existing knowledge on the impact of SARS-CoV-2 infection or COVID-19 on fertility and assisted reproduction, but also identifies gaps and offers suggestions for future research. The knowledge presented should help to provide evidence-based advice for practitioners and couples contemplating pregnancy alike, facilitating informed decision-making in an environment of significant emotional turmoil.

Review
Pelvic inflammatory disease is associated with complications that include infertility, chronic pelvic pain, ruptured tubo-ovarian abscess, and ectopic pregnancy. The diagnosis may be delayed when the presentation has nonspecific signs and symptoms. Even when properly diagnosed, pelvic inflammatory disease is often treated suboptimally. This review provides evidence-based recommendations for the diagnosis, treatment, disposition, and follow-up of patients with pelvic inflammatory disease. Arranging follow-up of patients within 48 to 72 hours and providing clear patient education are fundamental to ensuring good patient outcomes. Emerging issues, including new pathogens and\ evolving resistance patterns among pelvic inflammatory disease pathogens, are reviewed.

Review
Abdominal pain is the most common chief complaint in the Emergency Department. Abdominal pain is caused by a variety of gastrointestinal and nongastrointestinal disorders. Some frequently missed conditions include biliary pathology, appendicitis, diverticulitis, and urogenital pathology. The Emergency Medicine clinician must consider all aspects of the patient's presentation including history, physical examination, laboratory testing, and imaging. If no diagnosis is identified, close reassessment of pain, vital signs, and physical examination are necessary to ensure safe discharge. Strict verbal and written return precautions should be provided to the patient.

Human Reproduction (Oxford, England) May 2023Is the total number of oocytes retrieved with dual ovarian stimulation in the same cycle (duostim) higher than with two consecutive antagonist cycles in poor responders? (Randomized Controlled Trial)
Randomized Controlled Trial
The BISTIM study: a randomized controlled trial comparing dual ovarian stimulation (duostim) with two conventional ovarian stimulations in poor ovarian responders undergoing IVF.
STUDY QUESTION
Is the total number of oocytes retrieved with dual ovarian stimulation in the same cycle (duostim) higher than with two consecutive antagonist cycles in poor responders?
SUMMARY ANSWER
Based on the number of total and mature oocytes retrieved in women with poor ovarian response (POR), there is no benefit of duostim versus two consecutive antagonist cycles.
WHAT IS KNOWN ALREADY
Recent studies have shown the ability to obtain oocytes with equivalent quality from the follicular and the luteal phase, and a higher number of oocytes within one cycle when using duostim. If during follicular stimulation smaller follicles are sensitized and recruited, this may increase the number of follicles selected in the consecutive luteal phase stimulation, as shown in non-randomized controlled trials (RCT). This could be particularly relevant for women with POR.
STUDY DESIGN, SIZE, DURATION
This is a multicentre, open-labelled RCT, performed in four IVF centres from September 2018 to March 2021. The primary outcome was the number of oocytes retrieved over the two cycles. The primary objective was to demonstrate in women with POR that two ovarian stimulations within the same cycle (first in the follicular phase, followed by a second in the luteal phase) led to the retrieval of 1.5 (2) more oocytes than the cumulative number of oocytes from two consecutive conventional stimulations with an antagonist protocol. In a superiority hypothesis, with power 0.8 alpha-risk 0.05 and a 35% cancellation rate, 44 patients were needed in each group. Patients were randomized by computer allocation.
PARTICIPANTS/MATERIALS, SETTING, METHODS
Eighty-eight women with POR, defined using adjusted Bologna criteria (antral follicle count ≤5 and/or anti-Müllerian hormone ≤1.2 ng/ml) were randomized, 44 in the duostim group and 44 in the conventional (control) group. HMG 300 IU/day with flexible antagonist protocol was used for ovarian stimulation, except in luteal phase stimulation of the duostim group. In the duostim group, oocytes were pooled and inseminated after the second retrieval, with a freeze-all protocol. Fresh transfers were performed in the control group, frozen embryo transfers were performed in both control and duostim groups in natural cycles. Data underwent intention-to-treat and per-protocol analyses.
MAIN RESULTS AND THE ROLE OF CHANCE
There was no difference between the groups regarding demographics, ovarian reserve markers, and stimulation parameters. The mean (SD) cumulative number of oocytes retrieved from two ovarian stimulations was not statistically different between the control and duostim groups, respectively, 4.6 (3.4) and 5.0 (3.4) [mean difference (MD) [95% CI] +0.4 [-1.1; 1.9], P = 0.56]. The mean cumulative numbersof mature oocytes and total embryos obtained were not significantly different between groups. The total number of embryos transferred by patient was significantly higher in the control group 1.5 (1.1) versus the duostim group 0.9 (1.1) (P = 0.03). After two cumulative cycles, 78% of women in the control group and 53.8% in the duostim group had at least one embryo transfer (P = 0.02). There was no statistical difference in the mean number of total and mature oocytes retrieved per cycle comparing Cycle 1 versus Cycle 2, both in control and duostim groups. The time to the second oocyte retrieval was significantly longer in controls, at 2.8 (1.3) months compared to 0.3 (0.5) months in the duostim group (P < 0.001). The implantation rate was similar between groups. The cumulative live birth rate was not statistically different, comparing controls versus the duostim group, 34.1% versus 17.9%, respectively (P = 0.08). The time to transfer resulting in an ongoing pregnancy did not differ in controls 1.7 (1.5) months versus the duostim group, 3.0 (1.6) (P = 0.08). No serious adverse events were reported.
LIMITATIONS, REASONS FOR CAUTION
The RCT was impacted by the coronavirus disease 2019 pandemic and the halt in IVF activities for 10 weeks. Delays were recalculated to exclude this period; however, one woman in the duostim group could not have the luteal stimulation. We also faced unexpected good ovarian responses and pregnancies after the first oocyte retrieval in both groups, with a higher incidence in the control group. However, our hypothesis was based on 1.5 more oocytes in the luteal than the follicular phase in the duostim group, and the number of patients to treat was reached in this group (N = 28). This study was only powered for cumulative number of oocytes retrieved.
WIDER IMPLICATIONS OF THE FINDINGS
This is the first RCT comparing the outcome of two consecutive cycles, either in the same menstrual cycle or in two consecutive menstrual cycles. In routine practice, the benefit of duostim in patients with POR regarding fresh embryo transfer is not confirmed in this RCT: first, because this study demonstrates no improvement in the number of oocytes retrieved in the luteal phase after follicular phase stimulation, in contrast to previous non-randomized studies, and second, because the freeze-all strategy avoids a pregnancy with fresh embryo transfer after the first cycle. However, duostim appears to be safe for women. In duostim, the two consecutive processes of freezing/thawing are mandatory and increase the risk of wastage of oocytes/embryos. The only benefit of duostim is to shorten the time to a second retrieval by 2 weeks if accumulation of oocytes/embryos is needed.

American Journal of Obstetrics &... Jul 2022Pelvic inflammatory disease during pregnancy is a rare and an understudied occurrence with potential negative outcomes. (Review)
Review
BACKGROUND
Pelvic inflammatory disease during pregnancy is a rare and an understudied occurrence with potential negative outcomes.
OBJECTIVE
This study aimed to evaluate the outcomes of pregnant women with pelvic inflammatory disease with or without pelvic abscesses.
DATA SOURCES
We performed a systematic review of the literature using Ovid MEDLINE, Scopus, CINAHL, and PubMed (including Cochrane) with no time limitations.
STUDY ELIGIBILITY CRITERIA
Relevant studies on pelvic inflammatory disease during pregnancy were identified and considered eligible if they described at least 1 case of pelvic inflammatory disease after conception, defined as infection in one or more of the following: uterus, fallopian tubes, and ovaries; based on clinical findings, physical examination, and imaging with or without pelvic abscesses present. Only studies on pelvic inflammatory disease with or without tubo-ovarian abscesses during pregnancy that evaluated perinatal outcomes were included. Data on the risk factors, delivery methods, and maternal, fetal, and neonatal outcomes were collected.
METHODS
Reviewers screened all relevant titles using the inclusion/exclusion criteria and selected relevant articles for appraisal. A total of 49 cases with reported pelvic inflammatory disease, pelvic abscesses, or both were included.
RESULTS
After exclusion of articles that did not meet the inclusion criteria, 34 manuscripts describing the occurrence of pelvic inflammatory disease in 49 pregnancies were analyzed, focusing primarily on cases reported after 1971. The mean age of patients was 25±6.3 years, the mean gestational age at diagnosis was 19.0±10.3 weeks, and 67.6% of patients were multiparous. Of all included patients, 27 (62.8%) underwent exploratory laparotomies, 14 (32.6%) underwent unilateral salpingo-oophorectomies, and 11 (25.6%) underwent appendectomies. Of all the deliveries, 13 (50%) pregnancies were full term, 14 (53.8%) were cesarean deliveries, 10 (38.5%) were spontaneous vaginal deliveries, and 2 (7.7%) were cesarean hysterectomies. There were 26 (60.5%) cases of viable births (mean gestational age at delivery, 33.8±5.1 weeks) and 17 (39.5%) cases of nonviable births. Sepsis was a complication in 3 (7.0%) cases and caused 3 neonatal deaths.
CONCLUSION
Although rare, pelvic inflammatory disease can have severe health consequences. Risk factors for pelvic inflammatory disease development include maternal pelvic structural anomalies, a history of sexually transmitted infections, recent pelvic surgery, and in vitro fertilization or oocyte retrieval. Pelvic inflammatory disease can coincide with pregnancy and can occur in the second trimester. Making a prompt diagnosis can help to improve the outcomes; therefore, if a high enough suspicion exists, treatment should not be delayed.

IMPORTANCE
SARS-CoV-2 infection has had significant effects on the health of people worldwide. Whether SARS-CoV-2 infection during controlled ovarian stimulation (COS) is associated with laboratory outcomes in assisted reproductive technology remains unclear.
OBJECTIVE
To investigate the association between SARS-CoV-2 infection during COS with oocyte- and embryo-related outcomes.
DESIGN, SETTING, AND PARTICIPANTS
A multicenter cohort study was conducted of couples undergoing assisted reproductive technology treatments in 7 reproductive centers in 4 provinces in China from October 1, 2022, to December 31, 2022. All couples received nucleic acid testing for SARS-CoV-2 during COS. The SARS-CoV-2-positive group included couples in which either partner was infected with SARS-CoV-2. The SARS-CoV-2-negative group comprised couples without infection.
EXPOSURE
In the SARS-CoV-2-positive group, either partner was infected with SARS-CoV-2 during COS, defined as a positive test result for the SARS-CoV-2 antigen.
MAIN OUTCOMES AND MEASURES
Primary outcomes were the available embryo and blastocyst and top-quality embryo and blastocyst rates. Secondary outcomes were the number of oocytes retrieved, the mature oocyte rate, normal fertilization (2 pronuclei observed on day 1 after insemination [2PN]), oocyte degeneration, 2PN cleavage, and blastocyst formation rates.
RESULTS
A total of 585 heterosexual couples with infertility participated in the study (median [IQR] age for female partners, 33 [30-37] years), with 135 couples in the SARS-CoV-2-positive group and 450 in the SARS-CoV-2-negative group. The characteristics of the groups were similar. The SARS-CoV-2-positive group had a significantly lower top-quality embryo rate (odds ratio [OR], 0.83; 95% CI, 0.71-0.96), top-quality blastocyst rate (OR, 0.59; 95% CI, 0.45-0.77), available blastocyst rate (OR, 0.70; 95% CI, 0.59-0.82), and blastocyst formation rate (OR, 0.61; 95% CI, 0.52-0.71) than the SARS-CoV-2-negative group. Analysis of the associations of infection by sex showed that the female positive group had impaired oocyte and embryo quality regarding mature oocyte rate, 2PN cleavage rate, top-quality embryo rate, blastocyst formation rate, available blastocyst rate, and top-quality blastocyst rate compared with the SARS-CoV-2-negative group. Compared with the SARS-CoV-2-negative group, the male positive group and the group of couples with both positive partners had significantly decreased available blastocyst rate, top-quality blastocyst rate, and blastocyst formation rate compared with the SARS-CoV-2 negative group.
CONCLUSIONS AND RELEVANCE
In this cohort study, SARS-CoV-2 infection during COS was negatively associated with embryo and blastocyst quality. Reproductive physicians should be more attentive to patients with SARS-CoV-2 infection during COS and should give couples who have been infected adequate counseling.
