Guideline for gynecological practice in Japan: Japan Society of Obstetrics and Gynecology and Japan Association of Obstetricians and Gynecologists 2023 edition.

Twelve years after the first edition of The Guideline for Gynecological Practice, which was jointly edited by The Japan Society of Obstetrics and Gynecology and The Japan Association of Obstetricians and Gynecologists, the 5th Revised Edition was published in 2023. The 2023 Guidelines includes 5 additional clinical questions (CQs), which brings the total to 103 CQ (12 on infectious disease, 30 on oncology and benign tumors, 29 on endocrinology and infertility and 32 on healthcare for women). Currently, a consensus has been reached on the Guidelines, and therefore, the objective of this report is to present the general policies regarding diagnostic and treatment methods used in standard gynecological outpatient care that are considered appropriate. At the end of each answer, the corresponding Recommendation Level (A, B, C) is indicated.

Exposure to the reproductive endocrinology subspecialty among obstetrics and gynecology residency programs.

PURPOSE: Prior studies found that Ob-gyn trainees believe they have inadequate experience in the REI subspecialty. We evaluated the amount of time devoted to REI within the 4-year rotation schedule of ACGME-accredited Ob-gyn residency programs. METHODS: A list of current Ob-gyn residency programs, both with and without REI fellowships, was created using ACOG and ACGME databases. The programs' websites were reviewed, or the program coordinator was queried to determine the length and year of REI rotation, and the career or fellowships pursued by alumni. Wilcoxon rank sum test was utilized to assess differences in total REI rotation time between REI-affiliated and non-affiliated programs. Spearman's correlation was utilized to assess the association between total REI exposure and the percentage of alumni pursuing REI fellowships. RESULTS: Cumulative length of REI rotations throughout residency ranged from 0 to 20 weeks. Mean cumulative rotation length was greater in non-REI than in REI-affiliated programs (7.4 weeks vs. 6.1 weeks, p = 0.007). However, REI-affiliated programs had greater exposure to REI rotations during the first 2 years of residency (3.9 weeks vs 3.1 weeks, p = 0.042). Among all programs, 24% had the REI rotation in PGY-1, 61% in PGY-2, 50% in PGY-3, and 16% in PGY-4. The proportion of alumni matching in REI fellowship was significantly greater in REI-affiliated programs than non-REI affiliated programs (9.5% vs. 3.1%, p < 0.001). CONCLUSION: Compared to non-REI affiliated programs, Ob-gyn residencies affiliated with REI fellowships spend less time throughout residency training in REI rotations while sending a greater proportion of residents to REI fellowships.

Protective effects of dichloroacetic acid on endometrial injury and ovarian reserve in an experimental rat model of diabetes mellitus.

AIM: To study (1) ovarian and endometrial damage caused by the hyperglycemia and (2) the effects of dichloroacetic acid (DCA) on follicular reserve and endometrial damage in streptozocin induced diabetic rats. METHODS: This study consisted 24 rats randomly separated into three groups. A diabetes model was achieved in 16 rats experimentally, and normoglycemic eight rats were assigned as control group (Group 1). The rats with diabetes were randomly separated to two groups: 1 mL/kg/day intraperitoneal 0.9% NaCl was given to eight rats as diabetic vehicle (Group 2) and 10 mg/kg/day DCA was given to other eight rats as DCA treated group (Group 3). Hysterectomy with bilateral oophorectomy was performed for histopathological evaluation and blood samples were collected after 4 weeks. RESULTS: Diabetes caused ovarian and endometrial damage (p < 0.0001). Pentraxin-3 (PTX-3), lactic acid, and transforming growth factor-beta (TGF-ß) were higher (p < 0.05, p < 0.05, and p < 0.0001, respectively), whereas anti-Mullerian hormone (AMH) was lower in diabetic rats (p < 0.05). These findings reflected the diabetic damage in the genital tract and diminished ovarian reserve occurred via fibrosis, severe inflammation, and oxidative stress. DCA improved the histopathological fibrosis and degeneration in the ovaries and endometrium (p < 0.05). There was a concominant decrease of TGF-ß and lactic acid levels with DCA treatment (p < 0.05). DCA also improved ovarian reserve with higher AMH levels (p < 0.05). CONCLUSIONS: The several unfavored changes in the endometrium and ovaries due to diabetes have been determined in this present study. DCA might provide the continuity of the endometrial cycle, physiological endometrial structure, ovarian follicular growth, oocyte maturation, and physiological ovarian function by decreasing the lactate levels via inhibiting pyruvate dehydrogenase kinase enzyme.

Guideline for Gynecological Practice in Japan: Japan Society of Obstetrics and Gynecology and Japan Association of Obstetricians and Gynecologists 2020 edition.

Nine years after the first edition of The Guideline for Gynecological Practice, which was jointly edited by The Japan Society of Obstetrics and Gynecology and The Japan Association of Obstetricians and Gynecologists, the 4th Revised Edition was published in 2020. The 2020 Guidelines includes 4 additional clinical questions (CQ), which brings the total to 99 CQ (12 on infectious disease, 29 on oncology and benign tumors, 29 on endocrinology and infertility and 29 on healthcare for women). Currently, a consensus has been reached on the Guidelines, and therefore, the objective of this report is to present the general policies regarding diagnostic and treatment methods used in standard gynecological outpatient care that are considered appropriate. At the end of each answer, the corresponding Recommendation Level (A, B, C) is indicated.

Gender inequality in leadership and academic rank in academic reproductive endocrinology programs.

PURPOSE: To identify gender differences in leadership and academic rank within academic reproductive endocrinology (REI) programs with fellowships in the USA. METHODS: Official institutional websites of the 2017-2018 American Board of Obstetrics and Gynecology (ABOG)-accredited reproductive endocrinology fellowship programs were reviewed, and gender representation at each leadership position and academic rank (Division and Fellowship Director and Full, Associate, and Assistant Professor) was recorded. Univariate comparisons were performed using Chi-square tests, with significance at p < 0.05. RESULTS: Among 49 ABOG-accredited reproductive endocrinology programs, 263 faculty were identified, 129 (49.0%) male and 134 (51.0%) female. Division directors were 69.3% male and 30.7% female (p = 0.006). Similarly, fellowship directors were 65.3% male and 34.6% female (p = 0.03). Full professors (n = 101) were more frequently male (70.3% vs. 29.7%, p < 0.001). There was no difference in gender among associate professors (n = 60, 51.7% male vs. 48.3% female, p = 0.79), while significantly more assistant professors were female than male (n = 102, 73.6% vs. 26.4%, p < 0.001). CONCLUSION: While a majority of residents in obstetrics and gynecology and half of reproductive endocrinology academic faculty are female, women are still underrepresented among leadership positions and full professors in academic reproductive endocrinology programs with fellowship programs.

Guidelines for office gynecology in Japan: Japan Society of Obstetrics and Gynecology (JSOG) and Japan Association of Obstetricians and Gynecologists (JAOG) 2017 edition.

Six years after the first edition of The Guideline for Gynecological Practice, which was jointly edited by The Japan Society of Obstetrics and Gynecology and The Japan Association of Obstetricians and Gynecologists, the third revised edition was published in 2017. The 2017 Guidelines includes 10 additional clinical questions (CQ), which brings the total to 95 CQ (12 on infectious disease, 28 on oncology and benign tumors, 27 on endocrinology and infertility and 28 on healthcare for women). Currently a consensus has been reached on the Guidelines and therefore the objective of this report is to present the general policies regarding diagnostic and treatment methods used in standard gynecological outpatient care that are considered appropriate. At the end of each answer, the corresponding recommendation level (A, B, C) is indicated.

Review of patient decision-making factors and attitudes regarding preimplantation genetic diagnosis.

The increasing technical complexity and evolving options for repro-genetic testing have direct implications for information processing and decision making, yet the research among patients considering preimplantation genetic diagnosis (PGD) is narrowly focused. This review synthesizes the literature regarding patient PGD decision-making factors, and illuminates gaps for future research and clinical translation. Twenty-five articles met the inclusion criteria for evaluating experiences and attitudes of patients directly involved in PGD as an intervention or considering using PGD. Thirteen reports were focused exclusively on a specific disease or condition. Five themes emerged: (1) patients motivated by prospects of a healthy, genetic-variant-free child, (2) PGD requires a commitment of time, money, energy and emotions, (3) patients concerned about logistics and ethics of discarding embryos, (4) some patients feel sense of responsibility to use available technologies, and (5) PGD decisions are complex for individuals and couples. Patient research on PGD decision-making processes has very infrequently used validated instruments, and the data collected through both quantitative and qualitative designs have been inconsistent. Future research for improving clinical counseling is needed to fill many gaps remaining in the literature regarding this decision-making process, and suggestions are offered.

Interactive case-based learning improves resident knowledge and confidence in reproductive endocrinology and infertility.

Resident physicians' scores on the REI section of the CREOG exam are traditionally low, and nearly 40% of house staff nation-wide perceive their REI knowledge to be poor. We aimed to assess whether an interactive case-based group-learning curriculum would narrow the REI knowledge gap by improving understanding and retention of core REI concepts under the time constraints affecting residents. A three-hour case-based workshop was developed to address four primary CREOG objectives. A multiple-choice test was administered immediately before and after the intervention and 7 weeks post-workshop, to evaluate both knowledge and confidence. Following the intervention, residents self-reported increased confidence with counseling and treatment of PCOS, ovulation induction cycle monitoring, counseling and treatment of POI, and breaking bad news related to infertility (p < 0.05). The multiple-choice exam was re-administered 7 weeks post-intervention, and scores remained significantly improved compared to pre-workshop scores (p < 0.05). At that time, all residents either strongly agreed (91.7%) or agreed (8.3%) that the case-based interactive format was preferable to traditional lecture-based teaching. In conclusion, a nontraditional curriculum aimed at teaching core REI concepts to residents through interactive case-based learning can be successfully integrated into a residency curriculum, and significantly improves knowledge and confidence of critical concepts in REI.

Predicting a successful match among applicants to reproductive endocrinology and infertility fellowship.

OBJECTIVE: To identify independent predictors of a successful match to reproductive endocrinology and infertility (REI) fellowships, and to develop and internally validate a prediction model for REI match results. DESIGN: Retrospective cohort study. SETTING: University-based institution. PARTICIPANTS: Reproductive endocrinology and infertility fellowship applications sent to the University of Pennsylvania from 2019 to 2023 (excluding 2020), which represented nearly all REI applicants nationally according to National Resident Matching Program data. INTERVENTION(S): Demographics, education, training, and academic achievements. MAIN OUTCOME MEASURE(S): Match result, confirmed through online search and communication with program administrators. Univariate analyses identified variables associated with match, which were then included in multivariable models to identify independent predictors. Bootstrapping was used to assess model discrimination and calibration. The final model was integrated into a web-based tool. RESULT(S): Of 286 applications (99.0% of REI applications to the National Resident Matching Program), 199 (69.6%) resulted in a successful match. In univariate analyses, variables associated with match were younger age, attendance at an allopathic US medical school, United States Medical Licensing Examination (USMLE) and Council on Resident Education in Obstetrics and Gynecology scores, residency rank, residency affiliation with a fellowship, research experiences, first-author publications, abstracts/articles in progress, and poster presentations. In the adjusted model, independent predictors of match included residency affiliation with an REI fellowship (adjusted odds ratio [aOR], 5.43; 2.02-14.64), residency rank (aOR, 1.77; 1.25-2.50), USMLE score (aOR, 1.05; 1.02-1.08), at least one first-author publication (aOR, 2.32; 1.08-4.96), projects in progress (aOR, 1.26; 1.02-1.55), and poster presentations (aOR, 1.07; 1.00-1.15). Attendance at an international medical school was a negative predictor (aOR, 0.32; 0.11-0.88). The model achieved an area under the curve of 0.883, with 88.5% sensitivity and 65.8% specificity. A refined model without USMLE scores maintained strong performance (C-statistic, 0.85; 0.81-0.91; calibration slope, 0.91; 0.72-1.24). CONCLUSION(S): Affiliation with an REI fellowship, residency reputation, and research output strongly predicted match success. Gender, race, and ethnicity were not major predictors, yet underrepresentation of certain racial and ethnic groups limited the power to detect potential differences. Our prediction model correctly classified >75% of candidates' match results. These findings may help candidates optimize applications and estimate chances of a successful match into REI fellowship, as well as assist programs in critically reviewing their selection criteria for fellowship match.

Which obstetrics-gynecology residency programs are training future reproductive endocrinology and infertility fellows? An observational study.

Objective: To identify where reproductive endocrinology and infertility (REI) fellows trained for residency. Design: Observational, cross-sectional study. Setting: Not applicable. Subjects: Reproductive endocrinology and infertility fellows. Interventions: Not applicable. Main Outcome Measures: Percentage of fellows who completed residency training at an institution with an REI fellowship program. Results: A total of 289 fellows were identified among the graduating fellowship classes from 2023-2027. Of those fellows, 69.9% completed residency at an institution that had an associated REI fellowship program, and 19.7% remained at the same institution for residency and fellowship. In the last 5 years, 34.4% of obstetrics and gynecology residency programs have had at least 1 resident enter REI fellowship. Conclusions: Most matriculated REI fellow physicians train at residency programs that have an associated REI fellowship program.

Meeting the demand for fertility services: the present and future of reproductive endocrinology and infertility in the United States.

The field of reproductive endocrinology and infertility (REI) is at a crossroads; there is a mismatch between demand for reproductive endocrinology, infertility and assisted reproductive technology (ART) services, and availability of care. This document's focus is to provide data justifying the critical need for increased provision of fertility services in the United States now and into the future, offer approaches to rectify the developing physician shortage problem, and suggest a framework for the discussion on how to meet that increase in demand. The Society of REI recommend the following: 1. Our field should aggressively explore and implement courses of action to increase the number of qualified, highly trained REI physicians trained annually. We recommend efforts to increase the number of REI fellowships and the size complement of existing fellowships be prioritized where possible. These courses of action include: a. Increase the number of REI fellowship training programs. b. Increase the number of fellows trained at current REI fellowship programs. c. The pros and cons of a 2-year focused clinical fellowship track for fellows interested primarily in ART practice were extensively explored. We do not recommend shortening the REI fellowship to 2 years at this time, because efforts should be focused on increasing the number of fellowship training slots (1a and b). 2. It is recommended that the field aggressively implements courses of action to increase the number of and appropriate usage of non-REI providers to increase clinical efficiency under appropriate board-certified REI physician supervision. 3. Automating processes through technologic improvements can free providers at all levels to practice at the top of their license.

Subspecialty Faculty in Obstetrics and Gynecology: Distribution, Demographics, and Implications for Training and Clinical Practice.

OBJECTIVE: The objective of this study was to quantify the subspecialist workforce involved in the clinical education of Obstetrics and Gynecology (OBGYN) residents and to provide an overview of the subspecialist faculty workforce geographic distribution and demographics. METHODS: This cross-sectional, observational study used public data collected from July 1, 2022, through August 31, 2022. A list of Obstetrics and Gynecology residency programs, their sponsoring institutions/locations, and affiliated locations was compiled from the American Medical Association's Fellowship and Residency Electronic Interactive Database. Faculty subspecialists' names were collected by manually searching each program's website. Demographics were collected from the National Plan and Provider Enumeration System. Subspecialty faculty who had completed an Obstetrics and Gynecology residency, were fellowship trained, and/or had board certification in the subspecialty were included in the study. RESULTS: A total of 4,659 subspecialist faculty were identified from 278 residency programs, representing 81.5% of the total subspecialist workforce in Obstetrics and Gynecology (n=5,716). Of the subspecialists identified, 2,838 were faculty at sponsoring institutions, representing 49.7% of the entire subspecialist workforce; the remainder worked with residents at affiliate locations. Our results showed 59.9% of subspecialists were female and 40.1% were male; 97.0% were allopathic subspecialists. The largest proportion of subspecialists were in the age group of 40-49 years (36.6%). Subspecialists were present in 45 states, with the exception of Alaska, Idaho, Montana, North Dakota, South Dakota, and Wyoming. CONCLUSION: Most of the Obstetrics and Gynecology subspecialty workforce is involved in the clinical education of OBGYN residents, with half of the workforce on faculty at the residency program sponsor site. The subspecialty faculty workforce is primarily female, has an allopathic degree, is mid-career, and is geographically diverse.

Do gender differences exist in letters of recommendation for reproductive endocrinology and infertility fellowship?

OBJECTIVE(S): To determine if gender differences exist in letters of recommendation (LORs) for reproductive endocrinology and infertility fellowship. DESIGN: Cohort study. SETTING: Academic medical center. PATIENTS: A cohort of applicants to a reproductive endocrinology and infertility fellowship program at a single Midwestern academic institution in a single year. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Quantitative measures included linguistics inquiry and word count analysis, with 4 summary variables and 25 word categories, to quantify tone and themes present by gender. Performing qualitative analysis in parallel to linguistic analysis allowed for the exploration of themes not conveyed in quantitative methods alone. Qualitative measures included the frequency of code themes in LOR by applicant gender. RESULTS: There were 272 letters from 72 applicants, 54 (76%) of which were women and 17 (24%) were men. One applicant was excluded because gender information was not specified; 269 letters were included in the quantitative linguistics and qualitative coding analysis. One hundred 10 letters (41%) were written by women and 159 (59%) by men. LOR written for men had a higher mean word count than those written for women (537 vs. 474, P=.04). Linguistics Inquiry and Word Count analysis exhibited more risk words used to describe men applicants (P=.01). When comparing word categories by letter writer gender, women letter writers more frequently used communal, affect, and home word categories whereas men writers more frequently used affiliation-related words. Qualitative analysis revealed that letters for men applicants described leadership, altruism, rapport with patients, and strong endorsements more frequently, whereas women applicants' letters more often mentioned doubt raisers and disclosures of personal life. In addition, letters for women applicants more often described candidates as drama free, not easy to "fluster," and not complainers. Furthermore, letters for women more frequently disclosed parenthood status. CONCLUSIONS: Gender differences exist among both letter writers and applicants. Qualitative analysis revealed that women applicants were more likely to be described with doubt raisers and personal life disclosures, whereas men were more likely to be described by their altruism and with a strong endorsement. Increasing bias awareness and implementing mitigation strategies would improve gender equity in LOR.

Reproducible research practices and transparency in reproductive endocrinology and infertility articles.

OBJECTIVE: To analyse the published literature in reproductive endocrinology and infertility (REI) to examine the transparency and the use of reproducible research practices of the scientific literature and to identify possible avenues for improvement. DESIGN: Meta-epidemiologic study. We examined the first 20 consecutive full-text original articles presenting primary data from five REI-specific journals for 2013 and for 2018, and eligible REI articles published in 2013-2018 in five high-impact general journals. Eligible articles were required to be full-text original articles, presenting primary data. SETTING: Not applicable. PATIENT(S): Not applicable. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Each article was assessed for study type, trial registration, protocol and raw data availability, funding and conflict of interest declarations, inclusion in subsequent systematic reviews and/or meta-analyses, sample size, and whether the work claimed to be novel or replication. Sample sizes and citation counts also were obtained. RESULT(S): A total of 222 articles were deemed eligible; 98 from REI journals published in 2013, 90 from REI journals published in 2018, and 34 from high-impact journals. There were 37 studies registered, 15 contained a protocol, and two stated actively that they were willing to share data. Most studies provided a statement about funding and conflicts of interest. Two articles explicitly described themselves as replications. All randomized controlled trial published in REI journals were registered prospectively; many meta-analyses were not registered. High-impact journal articles had a greater median sample size and more citations and were more likely to be registered, to have a protocol, and to claim novelty explicitly when compared with REI 2013 and 2018 articles. CONCLUSION(S): Research in REI can be improved in prospective registration, routine availability of protocols, wider sharing of raw data whenever feasible, and more emphasis on replication.

Academic pursuits in board-certified reproductive endocrinologists.

OBJECTIVE: To determine research interests of reproductive endocrinology and infertility (REI) physicians and assess their academic productivity. DESIGN: A questionnaire composed by the Society for REI (SREI) board members was e-mailed to members. PubMed was queried to quantify peer-reviewed publications. SETTING: An internal SREI questionnaire to members and online publication search. PATIENT(S): Not applicable. INTERVENTION(S): Questions involving research being performed, funding, relevance to fellow thesis, and important areas of future research. Publications were ascertained in the past 3 years, past 10 years, and total publications for SREI members. MAIN OUTCOME MEASURE(S): Question responses and number of peer-reviewed publications. RESULT(S): Most respondents currently conduct research, which was predominantly clinical. One-third have current research funding and two-thirds were ever funded. One-third had a National Institutes of Health grant and about half were principal investigators. Two-thirds had a basic science fellow thesis and 44% of respondents perform research related to their fellowship thesis. Important research areas included infertility outcomes, implantation, preimplantation genetic testing, and genetics. In the past 3 years, SREI members published 3,408 peer-reviewed articles (mean ± standard deviation [SD], 4.4 ± 9.0). In the past 10 years, SREI members had 10,162 peer-reviewed publications (mean±SD, 13.0 ± 24.3). When all publications were considered, SREI members published 24,088 peer-reviewed articles (mean±SD, 30.9 ± 53.0). CONCLUSION(S): The REI fellows have learned to construct scientific articles, which will help them to better interpret the literature in the care of patients. The SREI members continue to pursue scientific investigation, commonly related to their fellowship thesis. Respondents support SREI funding research; the success of which should be judged by publications. Overall, SREI members have demonstrated significant academic productivity and published about 1,000 articles/year for the past 10 years, affirming the importance of research training.

Gender inequality in salaries among reproductive endocrinology and infertility subspecialists in the United States.

OBJECTIVE: To determine whether and by how much pay among board-certified or -eligible reproductive endocrinology and infertility (REI) subspecialists in the United States differs by gender. DESIGN: Cross-sectional Web-based survey. SETTING: Not applicable. PATIENT(S): None. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): The primary outcome measure was continuous income, which was calculated using the mid-point of salary and bonuses as reported in the survey. Secondary outcomes included income based on type of practice, years in practice, region of the country in practice, and race/ethnicity of survey respondent. RESULT(S): Among 215 responses, 49% were female and 95% were full Society for Reproductive Endocrinology and Infertility members. Fewer women reported being in private practice than men (45% vs. 64%). Female gender was associated with an income gap of 27% in unadjusted comparisons. When adjusted for years in practice and type of practice (private vs. other), the gap diminished to 21% but remained significant, with men reporting higher incomes than women. CONCLUSION(S): The gender pay gap present among physicians and obstetricians and gynecologists more widely persists among REI subspecialists even when accounting for characteristics related to differences in pay. Acknowledging the pay gap among REI subspecialists is the first step in working toward gender-neutral compensation for equivalent work.

Patients' preimplantation genetic testing decision-making experience: an opinion on related psychological frameworks.

The process of deciding whether to pursue preimplantation genetic testing (PGT) of an embryo is highly stressful for individuals and couples and has adverse emotional consequences (e.g. distress and uncertainty). PGT influences patients' lives in both positive and negative ways and is experienced at an individual level, as a dyadic unit, as a family member and as part of the society. Here, we argue that providing a conceptual framework with which to understand the `experience of decision making' about PGT for monogenic disease (PGT-M) testing specifically, as well as the factors contributing to `decisional distress' and `uncertainty' that patients endure as a result-apart from what decision they make-is crucial to optimizing patient counseling, satisfaction and outcomes in the field of ART. Derived from psychological theory, the framework proposed here identifies three categories of contributing factors to decisional distress and uncertainty in considering PGT-M; namely, 'intraindividual', 'interpersonal' and 'situational' factors. We reviewed evidence from the PGT literature to inform our framework. Well-accepted theories of stress and health decision making were also reviewed for their relevance to PGT-M decision making, focusing on potential distress and uncertainty. Our novel conceptual framework can be used to inform clinical practice, to advance research and to aid the development of interventions for individuals and couples who are deciding whether or not to use PGT-M. Alleviating emotional distress and uncertainty can improve patients' well-being during their reproductive journey.

Knowledge gaps in male infertility: a reproductive endocrinology and infertility perspective.

Reproductive research has moved forward at a remarkable pace. Some of these advances are the result of a separation between male and female specialties, allowing focused study in specific areas of the field. However, the different training programs between male and female fertility specialists has created an environment in which some discoveries are not put in the greater context of clinical care. At times, interventions have been measured against surrogate markers of outcome that may not impact the most meaningful outcome for patients-the delivery of a healthy neonate. For example, medical and surgical interventions that use changes in semen parameters may have a limited impact on the likelihood of achieving a live birth due to the limitations inherent in the semen analysis for predicting outcomes. Other commonly used tests, such as sperm DNA fragmentation assays provide promising biological plausibility to account for subfertility of some male partners. However, until well defined thresholds for predicting outcomes in different treatment scenarios are available, changes in sperm DNA fragmentation testing is not an adequate outcome for measuring the utility of interventions. The biggest limitation for these tests remains their analysis of bulk semen. Tests allowing interrogation of the reproductive competence of a given sperm, while allowing that sperm to be used in assisted reproductive technology procedures remain elusive. Progress toward reaching this end (whether by hyaluronic acid binding, IMSI, or Ramen spectroscopy) is underway, but much remains to be learned. Achieving testing and capture of individual sperm would better facilitate studies that measure the most meaningful outcome for patients and providers-the delivery of a healthy baby.
