RESUMEN
Purpose: To investigate factors that obstruct and facilitate the use of the foster parent and special adoption systems (i.e., foster systems) by cancer survivors, and examine how to effectively provide information. Methods: This was a cross-sectional study that compared the results of a questionnaire survey of foster parents and adoptive parents (i.e., foster parents) who were and were not cancer survivors belonging to foster parent associations in 33 locations in Japan. This study was supported by a 2022 Ministry of Health, Labor, and Welfare Grant-in-Aid for Scientific Research (Grant No. 20EA1004). Results: "Lack of information," an obstructive factor and "Sympathetic understanding and cooperation from my partner and family," a facilitative factor were the highest score in both groups. Significant differences between the two groups were found in "Support from government agencies and others for foster parents," a facilitative factor, which was lower in the cancer survivors' group. There were no other significant differences between both the groups. Conclusion: This study found that when considering the use of the foster systems, a lack of information was the biggest obstructive factor and family understanding was the most helpful for both cancer survivors and noncancer groups. It was thought that stronger government support for cancer survivors might encourage cancer survivors to consider becoming foster parents. It would be effective for cancer treatment facilities, reproductive medical facilities, the government, and foster parent associations to work together to provide information carefully to cancer survivors.

BACKGROUND: A couples' psycho-educational program called Oncofertility! Psycho-Education and Couple Enrichment (O!PEACE) therapy was created and its effect when provided before cancer treatment was examined. METHODS: This multicenter randomized controlled trial with nonmasking, parallel two-group comparison enrolled women aged 20 to 39 years with early-stage breast cancer and their partners. They were randomly assigned to receive O!PEACE (37 couples) or usual care (37 couples). Primary end points were cancer-related posttraumatic stress symptoms, symptoms of depression, and anxiety. Secondary end points were stress-coping strategies, resilience, and marital relationship. RESULTS: Women receiving psycho-educational therapy had significantly reduced Impact of Event Scale-revised version for Japanese scores (p = .011, ηp 2 = = .089). For patients with Impact of Event Scale-revised version for Japanese scores at baseline ≥18.27, O!PEACE therapy improved these scores when compared with usual care (U = 172.80, p = .027, r = 0.258). A >5-point reduction was present in 59.3% and 30% of women in the O!PEACE therapy and usual-care groups, respectively. For partners, O!PEACE therapy significantly improved stress-coping strategies (95% CI, -0.60 to -0.05; p = .018, ηp 2 = = .074) and escape-avoidance marital communication (95% CI, -0.33 to -0.08; p = .001, ηp 2 = .136). O!PEACE therapy significantly improved the partners' support (95% CI, 0.10-0.50; p = .001, ηp 2 = .127), the rate of receiving fertility preservation consultations, and knowledge levels. CONCLUSIONS: O!PEACE therapy before cancer treatment can improve posttraumatic stress symptoms, stress-coping behavior, and marital relationships. Larger sample sizes and longer term follow-up are required. PLAIN LANGUAGE SUMMARY: A psycho-educational program, the Oncofertility! Psycho-Education and Couple Enrichment (O!PEACE) therapy program was developed and evaluated for women diagnosed with breast cancer and their partners. A multicenter randomized controlled trial showed that the O!PEACE psycho-educational therapy, with only two precancer treatment sessions, can reduce cancer-related posttraumatic stress symptoms and improve oncofertility knowledge and marital relationships in young adult patients with breast cancer. The therapy could also improve stress-coping strategies in marital communications with their partners. Couples may use O!PEACE psycho-educational therapy to consider fertility preservation and improve their psychosocial aspects.

This study aimed to assess outcomes of microdissection testicular sperm extraction (MD-TESE) and identify predictors for sperm retrieval (SR) in patients with non-mosaic Klinefelter syndrome (NM-KFS). We retrospectively evaluated 37 patients with NM-KFS who underwent MD-TESE. Data of age at operation, body mass index (BMI), testicular volume, serum luteinizing hormone (LH), follicle stimulating hormone (FSH), preoperative and postoperative testosterone levels with reduction ratio between the two values, and FSH/preoperative testosterone ratio were analysed. These patients were divided into two groups according to success or failure of SR: the successful and failure groups. Factors related to SR were evaluated by statistical analyses using the Mann-Whitney U test and logistic regression modelling. Regarding these factors, the cut-off level was specified using the receiver operating characteristics (ROC) curve. Moreover, the percentage of SR at that level was assessed. A simple scoring model was developed based on the multivariate analysis. Fourteen patients underwent successful SR, whereas 23 experienced failure SR. Statistical analysis found preoperative testosterone and FSH levels to be significant factors associated with SR. On the ROC curve, the cut-off levels for preoperative testosterone and FSH were 2.34 ng/ml and 33.2 mIU/ml respectively. A new scoring model was developed, consisting of preoperative testosterone (≥2.34 ng/ml) and FSH (≤33.2 mIU/ml). The sperm retrieval rates (SRRs) were clearly discriminated by stratification according to the scoring model. The SRR of the cases of scores of 2, 1 and 0 were 87.5%, 31.6% and 10% respectively. At our hospital, the SRR of MD-TESE in patients with NM-KFS was 37.8%. The patients with high testosterone and low FSH levels tended to demonstrate successful SR.

Varicocele is a common cause of male infertility. It is reported that low sperm concentration, motility and morphology are indicative of increased sperm DNA fragmentation index (DFI) in men with varicocele. Although research has been conducted into the relationship between varicocele and DFI, little is known about seminal oxidation-reduction potential (ORP) in varicocele patients. We assessed the relationship between varicocele with seminal ORP and sperm DFI in both fertile and infertile men. This prospective case-control study compared the findings from infertile men with varicocele to those of men with normal spermatogenesis without varicocele. Semen samples were collected and assessed using the WHO (2010) guidelines. ORP was measured (mV) and normalized to sperm concentration (mV/106 sperm/mL). DFI was measured using the sperm chromatin structure assay (SCSA) method. For group comparisons, only samples with a concentration >1 × 106 sperm/mL were included. Infertile men with varicocele had significantly lower mean sperm concentration, motility and total sperm count. Conversely, infertile men with varicocele had a significantly higher mean serum FSH level, and higher ORP and DFI values than fertile controls. ORP was higher in patients with varicocele and positively correlated with DFI (p < 0.01). ORP and DFI showed significant negative correlations with semen parameters (sperm concentration, motility and total sperm count) in infertile men with a varicocele.

Semen analysis has long been used to evaluate male fertility. Recently, several sperm function tests have been developed. Of those, the sperm DNA fragmentation index (DFI), which describes the status of the sperm DNA, is thought to be a suitable parameter for evaluating male fertility. However, there have been no large-scale studies on the sperm DFI of Japanese men. Therefore, we investigated the feasibility of using an in-house flow cytometry-based sperm DFI analysis based on the sperm DNA fragmentation test of sperm chromatin structure assay (SCSA) to assess male fertility in Japan. This study enrolled 743 infertile and 20 fertile Japanese men. To evaluate reproducibility, inter- and intraobserver precision was analyzed. A receiver operating characteristic curve analysis was used to set a cutoff value for the sperm DFI to identify men who could father children by timed intercourse or intrauterine insemination. The variability of the sperm DFI among fertile volunteers was determined. The relationship between semen parameters and the sperm DFI was assessed by Spearman's rho test. A precision analysis revealed good reproducibility of the sperm DFI. The cutoff value of sperm DNA fragmentation in infertile men was 24.0%. Semen volume had no relationship with the sperm DFI. Sperm concentration, sperm motility, total motile sperm count, and percentage of normal-shaped sperm were significantly and negatively correlated with the sperm DFI. The median sperm DFI was smaller in fertile volunteers (7.7%) than that in infertile men (19.4%). Sperm DNA fragmentation analysis can be used to assess sperm functions that cannot be evaluated by ordinary semen analysis.

The aim of this study is to evaluate how metallic artifacts in the lumbar spine can affect images obtained from magnetic resonance (MR) sequences. We performed a phantom experiment by scanning an agar containing an orthopedic metallic implant using 64-channel multidetector row computed tomography (CT) and a 3-tesla MR unit. We compared the reproducibility in each measurement, enlargement or reduction ratio of the CT and MR measurements, and signal deviation in each voxel from the control. The reproducibility on CT and multiacquisition variable-resonance image combination selective (MAVRIC SL) was good, but that on the other MR sequences showed either fixed bias or proportional bias. The reduction ratios of the distance between the nails were significantly smaller in MAVRIC SL than in the other MR sequences after CT measurements (p<0.001, respectively). MAVRIC SL was able to reduce the metallic artifact, permitting observation of the tissue surrounding the metal with good reproducibility.

We investigated the feasibility of agarose-gel microcapsules to cryopreserve extremely small numbers of sperm for assisted reproductive technology. Semen samples were collected from 16 patients attending the center for reproductive medicine male infertility clinic at a university hospital. We used agarose microcapsules to cryopreserve extremely small numbers of sperm from 16 patients with male infertility (10 with sperm concentration ≥1 million/mL; 6 with sperm concentration <1 million/mL). Six spermatozoa were injected into agarose-gel microcapsules and cryopreserved in a liquid nitrogen tank for 7 days. The Crytop method was used for cryopreservation as a control. After thawing, spermatozoa were recovered. Sperm recovery rates, motility and viability, and recovery time were compared.The post-thawing recovery rate, motility rate, and viability rate were higher whereas the recovery time was shorter in samples preserved using the agarose-gel microcapsule method compared to samples preserved using the Cryotop method in both the group with sperm concentrations of 1 million/mL or above and the group with sperm concentrations of less than 1 million/mL. This study demonstrated that using the agarose-gel microcapsule method increased post-thawing sperm recovery rate, sperm motility rate, and sperm viability rate, and reduced sperm recovery time compared with the conventional Cryotop method when cryopreserving samples with low sperm count. Although requiring further study, the agarose-gel microcapsule method shows much promise as a new option for freezing sperm.

OBJECTIVES: To evaluate whether the long-term usage of mirabegron, which was reported to have potential side effects on male reproductive organs in animal studies, was harmful to spermatogenesis in human testis. METHODS: Thirty consecutive patients with spinal cord injury (20-48 years old) who performed clean intermittent catheterization were involved in this study. Ten patients were treated with mirabegron (50 mg/d) for more than 2 years and refrained from using an antimuscarinic agent due to the side effects of constipation and dry mouth. Twenty patients were treated with neither anticholinergic agents nor mirabegron. All underwent conventional testicular sperm extraction. The sperm recovery rate and histopathologic findings of the retrieved testicular tissue were compared between both groups. RESULTS: We found no difference in the sperm recovery rate (P = .083) between both groups. Spinal cord injury patients treated with mirabegron had better spermatogenesis than those not treated with mirabegron (P < .05). CONCLUSIONS: From these data, we conclude that the therapeutic dose of mirabegron had no harmful effect on spermatogenesis in spinal cord injury patients of reproductive age.

PURPOSE: Cryptorchidism is one of the most common causes of non-obstructive azoospermia (NOA) in adulthood. Even if early orchidopexy is performed to preserve fertility potential, some patients still suffer from azoospermia. Fertility potential is significantly lower in bilateral than unilateral cryptorchidism. The aims of this study were to identify clinical parameters that predict the likely success of sperm recovery by microscopic testicular sperm extraction (micro-TESE) and also the likely outcome of intracytoplasmic sperm injection using sperm from NOA patients who submitted to bilateral orchidopexy. METHODS: Fifty-two NOA patients with a history of bilateral cryptorchidism underwent micro-TESE. The following clinical parameters were evaluated as predictive factors for successful sperm recovery: age at micro-TESE; age at orchidopexy; period from orchidopexy to micro-TESE; luteinizing hormone (LH); follicle-stimulating hormone (FSH); testosterone; average testicular volume; and body mass index. RESULTS: In the successful sperm retrieval group, average testicular volume was significantly greater, while serum LH and FSH, and body mass index were significantly lower. In a multivariate analysis, average testicular volume was positively correlated with successful sperm recovery. CONCLUSION: Our results indicate that testicular volume in NOA patients with bilateral cryptorchidism is a predictor for successful sperm recovery.
RESUMEN
Purpose: The oncofertility decision tree was developed by the oncofertility consortium as a tool to support healthcare professionals and patients through the complicated process of deciding the most appropriate fertility preservation strategy for patients with cancer. Various strategies include oocyte retrieval, oocyte donation, use of a gestational carrier and adoption. However, differences in the cultural and legal landscape present serious barriers to utilizing some of these strategies in Japan. Patients and Methods: We surveyed Japanese oncofertility stakeholders including 60 cancer survivors, 27 oncology facilities, 78 reproductive medicine facilities and 15 adoption agencies by a questionnaire to characterize awareness among oncofertility stakeholders in Japan about parenting options including adoption to inform work to establish guidelines for decision-making by cancer survivors in an oncofertility. Results: Our results indicate that oncologists and reproductive endocrinologists in Japan have an insufficient understanding of adoption that prevents them from adequately informing their patients. Japanese cancer survivors self-describe a lack in confidence in finding a suitable partner and raising a child. Contrastingly, of the 9 adoption agencies which responded, no agency included being a cancer survivor as a criterion for disqualification and 4 of 9 (44%) adoption agencies reported at least 1 adoption to a cancer survivor in the last year. Conclusion: Our work demonstrates that a cancer survivor's medical history itself is not a hurdle to adoption and investment in patient-provider education could be a viable strategy to improve the utilization of adoption as a fertility preservation strategy in Japan.

RESUMEN
This report examines how negative emotional expressions (NEE) influence the consequences of shared decision making (SDM) in oncofertility treatment among 32 young female cancer patients and 19 family members. Using a cross-sectional observational study, results showed that NEE influence the outcome consequences of SDM related to patients' decisions about desired treatment(s) and that the absence of negative emotional reactions to information from doctors was related to willingness to receive the desired treatment. This suggests that healthcare providers need to be sensitive to NEE of patients and their families, and highlights the need for psychological counseling before oncofertility consultation.

PURPOSE: To determine the optimal follicle localization for ovarian vitrification in adolescent and young adult (AYA)-aged (between 15 and 39 years of age) patients with cancer or primary ovarian insufficiency (POI). METHODS: In total, ovaries from 24 women were included in our study. These include women who received ovariectomy for fertility preservation before gonadotoxic treatments for cancer (n = 4), or for the treatment of POI by the in vitro activation method (n = 8), and other women and infants (0-3 years of age) whose ovaries were autopsied (n = 12). Before cryopreservation, a portion of the ovary sampled from cancer and POI patients was used for histological analysis. Depths of follicles from the surface of ovarian cortices were then measured by using digital imaging software. The locations of the follicles at different developmental stages in the ovarian cortex were noted. RESULTS: The mean depth at which the primordial and primary follicles were located was 271 µm in infants. This was deeper in women in their twenties, thirties, and forties (501, 462, and 493 µm, respectively). The majority of secondary follicles were located <1000 µm from the ovarian surface (mean depth, 639 µm). In regard to patients with POI, the mean depth of primordial and primary follicles was 566 µm, whereas 70% of secondary follicles were located >1000 µm deep. CONCLUSION(S): These findings suggest that <1 mm is a potential optimum thickness of normal ovarian tissue for vitrification and a requirement that thicker ovarian cortices include secondary follicles in POI patients.

PURPOSE: To identify the utility and issues associated with the use of decision trees in oncofertility patient care in Japan. METHODS: A total of 35 women who had been diagnosed with cancer, but had not begun anticancer treatment, were enrolled. We applied the oncofertility decision tree for women published by Gardino et al. to counsel a consecutive series of women on fertility preservation (FP) options following cancer diagnosis. Percentage of women who decided to undergo oocyte retrieval for embryo cryopreservation and the expected live-birth rate for these patients were calculated using the following equation: expected live-birth rate = pregnancy rate at each age per embryo transfer × (1 - miscarriage rate) × No. of cryopreserved embryos. RESULTS: Oocyte retrieval was performed for 17 patients (48.6%; mean ± standard deviation [SD] age, 36.35 ± 3.82 years). The mean ± SD number of cryopreserved embryos was 5.29 ± 4.63. The expected live-birth rate was 0.66. CONCLUSIONS: The expected live-birth rate with FP indicated that one in three oncofertility patients would not expect to have a live birth following oocyte retrieval and embryo cryopreservation. While the decision trees were useful as decision-making tools for women contemplating FP, in the context of the current restrictions on oocyte donation and the extremely small number of adoptions in Japan, the remaining options for fertility after cancer are limited. In order for cancer survivors to feel secure in their decisions, the decision tree may need to be adapted simultaneously with improvements to the social environment, such as greater support for adoption.

OBJECTIVE: Higuchi's transverse incision is made at a lower position than the Pfannenstiel transverse incision and is superior in terms of cosmetic outcomes. The purpose of this study was to examine the safety and efficacy of novel forms of reduced port surgery for ovarian cysts and uterine fibroids applying Higuchi's transverse incision. METHODS: In 33 patients with ovarian cysts who underwent low-position single-incision laparoscopic surgery (L-SILS)-modified single-port laparoscopy placed in the 2-3-cm Higuchi's incision above the pubis, patient's characteristics and perioperative outcomes were compared with those of patients who underwent multiport laparoscopy (n = 53). In addition, 18 patients with uterine fibroids who underwent dual-port laparoscopically assisted myomectomy without using power morcellators and conventional four-port laparoscopically assisted myomectomy were investigated. RESULTS: There were no significant differences between L-SILS and multiport laparoscopy in tumor diameter, bleeding, hospital stay, or postoperative pain. However, the L-SILS group demonstrated significantly shorter operative and pneumoperitoneum times (p < 0.01 and p < 0.01). In comparison with cases of uterine fibroids, no significant differences were found in maximum fibroid diameter, operative time, pneumoperitoneum time, or bleeding. However, the dual-port laparoscopically assisted myomectomy group demonstrated a significantly shorter length of hospital stay than the conventional laparoscopically assisted myomectomy group (p < 0.05). CONCLUSION: We reported novel forms of reduced port surgery applying Higuchi's transverse incision. It was suggested that these procedures are relatively simple, but ensure the same safety and efficacy as conventional methods. We intend to increase the number of cases and examine safety, efficacy, and patient satisfaction for these procedures.
RESUMEN
AIM: To evaluate the efficacy and adverse effects of Dienogest (DNG) over 53 weeks for the treatment of endometriosis. METHODS: DNG was administered to 75 patients with endometriosis over a period of 53 weeks. Medical charts were retrospectively examined on the efficacy and side effects. Reduction rates of ovarian chocolate cyst, adenomyosis and changes in serum estradiol and cancer antigen 125 concentration were measured. Adverse effects, patient evaluation of their symptoms and willingness to continue taking DNG were assessed by a questionnaire. RESULTS: The median duration of treatment was 87 weeks, with the longest follow-up duration being 120 weeks. Ovarian chocolate cysts were initially reduced; however, upon cessation of DNG treatment, an increase in size was observed. Adenomyosis lesions were reduced to some extent after 53 weeks of DNG treatment. In terms of adverse events, more than 60% (61.3%, 46/75) of patients experienced atypical genital bleeding. However, this did not prove to be a cause of discontinuation. We ceased DNG treatment in two cases because of lower abdominal pain and shoulder discomfort. CONCLUSIONS: Long term DNG treatment beyond one year for endometriosis proved to be effective and safe. Ovarian chocolate cysts were markedly reduced by short-term use of DNG, while a longer duration was required to reduce the size of adenomyosis. The decision regarding the choice of therapy lies with the individual clinician, considering a balance of efficacy with expense and adverse effects.

Purpose: To investigate potential indicators of in vitro fertilization (IVF) treatment outcome for female infertility patients aged ≥ 40 years based on the clinical course. Methods: We retrospectively examined results of 111 female infertility patients aged ≥ 40 years undergoing IVF treatment. We investigated the relationship between treatment cycle cancellation and the final outcome of IVF treatment in female infertility patients aged ≥ 40 years. Results: A total of 44 pregnancies were achieved. Overall pregnancy rate per initiated treatment cycle was 12.1%, and 24 spontaneous abortions occurred (54.5%). No woman aged ≥ 45 years achieved pregnancy. No patients conceived after 10 treatment cycles while 42 (11.5%) oocyte pick-up cycles and 120 (33.0%) embryo transfer cycles were canceled. Investigation of correlation with treatment cycle cancellation revealed that patients who experienced embryo transfer cancellation had a high spontaneous abortion rate while only a few patients who experienced oocyte pick-up cancellation achieved pregnancy and even fewer achieved a successful outcome. Conclusions: Our study suggests that, in addition to patient age and number of treatment cycles, cancellation of treatment cycle also provides another useful indicator for pregnancy outcome.
