The objective of our study was to review the experience of the fertility preservation programme in a tertiary-assisted reproduction unit in Hong Kong. Methods: This is a retrospective study involving men and women who were seen at a tertiary-assisted reproduction unit for fertility preservation counselling before gonadotoxic treatment from January 2005 to December 2020. Their medical records in paper and electronic forms were reviewed. Results: There were 75 consultations for female fertility preservation from 2010 to 2020 involving 72 women. Twenty women underwent 22 cycles of ovarian stimulation for oocyte or embryo cryopreservation, two of whom subsequently transported their oocytes abroad for further management and another two achieved natural conception. Additional four women who did not have oocyte or embryo cryopreservation achieved natural conception after cancer treatment. Eleven (15.2%) women were followed up at a reproductive endocrinology clinic after their cancer treatment. From 2005 to 2020, 265 men had sperm cryopreserved. Twenty-six (9.8%) came back to use the cryopreserved sperms, the wives of 13 (50.0%) of whom achieved an on-going pregnancy. Six of them transferred out and 40 discarded the cryopreserved sperms. Conclusions: There was generally an increasing number of patient consultations for fertility preservation in our Centre over the past decade but a consistently low rate of utilisation of cryopreserved gametes for both women and men. Post-cancer treatment fertility evaluation and monitoring was a major area of deficiency in Hong Kong. More structured post-cancer treatment fertility follow-up is needed.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74323202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical features of PCOS are heterogeneous and there are four clinical phenotypes: A (OD + HA + PCO); B (HA + OD); C (HA + PCO); and D (OD + PCO). Women with a PCOS phenotype that includes severe HA are at increased risk for pregnancy complications. There are currently no data on impact of PCOS phenotypes on in vitro fertilization (IVF) outcomes in Vietnamese women. This study investigated the association between PCOS phenotypes and IVF outcomes. Methods:This is a secondary analysis of a randomized controlled trial conducted in patients with PCOS undergoing IVF at IVFMD, My Duc Hospital, Ho Chi Minh City, Vietnam between January 2018 and April 2019. The primary outcome was live birth rate. Results:A total of 192 patients were included, of whom 33 patients had phenotype A (17.2%) and 159 had phenotype D (82.8%); no patients had phenotype B or C. Body mass index was significantly higher in patients with phenotype A than D (25.36 ± 4.78 versus 22.08 ± 3.21, [Formula: see text] = 0.001). There were no differences in laboratory and pregnancy outcomes between patients with phenotypes A and D. The live birth rate was lower in patients with phenotype A versus D, but the between-group difference did not reach statistical significance (33.3% vs. 42.8%, [Formula: see text] = 0.419).

Females, therefore, are born with a limited number of primary oocytes. This is in direct contrast to males in whom spermatogenesis continues during the entire lifespan following puberty. Here, we discuss possible evolutionary advantages that this confers and contrast this with age-related decline in oocyte quality that results in diminished fertility with advancing maternal age. We believe that a better understanding of these processes would be helpful in developing strategies to preserve fertility as maternal age increases, especially in the context of the current demographic shift with more and more women seeking fertility treatment at advanced age.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89308406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The subjects were 3,028 singletons who were born after fresh or frozen embryo transfer. The subjects were separated into five groups: C-IVF (n = 855), ICSI (n = 1,869), AOA (n = 42), IVM (n = 32), and TESE (n = 230). We evaluated obstetrical and neonatal outcomes calculating the adjusted odds ratio (AOR) using multivariable logistic regression analyses for fresh and frozen embryos and for cleavage and blastocyst transfer. The C-IVF group was used as a background control for the ICSI group. Moreover, the TESE, AOA, and IVM groups were compared to the ICSI group to evaluate the effects of the ICSI procedure itself. Results: The incidence of perinatal complications was significantly lower in the ICSI-fresh group (AOR = 0.29, 95% CI: 0.10–0.83, p ¡ 0.05). Regarding sex ratio, the IVM was significantly associated with sex ratio imbalance toward female in both fresh and frozen groups (AOR = 0.30, 95% CI: 0.10–0.96, AOR = 0.27, 95% CI: 0.07–0.98, p ¡ 0.05). On the other hand, there were no significant differences in preterm birth rate, low birth weight rate and congenital abnormalities rate between conventional IVF, ICSI, and the other groups. Conclusions: There were no negative effects on obstetrical and neonatal outcomes between conventional IVF and ICSI. Although this was a limited sample size study, advanced ART technologies such as AOA, IVM, and TESE also seem to have a low risk of adverse impact on obstetrical and neonatal outcomes but may have a slight impact on sex ratio.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74120585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared the reproductive outcomes of the euploid blastocysts developed on Day 5 versus Day 6. Methods: This single-center, retrospective observational study analyzed patients aged 25–45 years, who underwent intracytoplasmic sperm injection from December 2014 to November 2018. Depending on the day of trophectoderm biopsy, patients were categorized into Day-5 and Day-6 groups. Percentages of euploid embryos were calculated for both groups, and elective single euploid blastocysts were transferred in a frozen embryo transfer (FET) cycles. The study endpoints were the comparisons of the reproductive outcomes including clinical pregnancy rate (CPR), implantation rate (IR), miscarriage rate (MR), and live birth rate (LBR) between Day-5 and Day-6 euploid FET groups. Results: A total of 801 embryos from 184 patients were evaluated [Day 5 ([Formula: see text]=769); Day 6 ([Formula: see text]=32); 42.45% were euploid] with the rate of euploidy in Day-5 and Day-6 groups at 42.52% and 40.62%, respectively. A total of 126 patients underwent FET with 126 elective single euploid embryos (Day 5: 117; Day 6: 9).

The aim of this study is to clarify the efficacy of ERA leading to personalization of the day of embryo transfer (ET) in RIF patients. Methods: A retrospective study was performed for 94 patients with RIF who underwent ERA between July 2015 and December 2019. Pregnancy outcomes in a previous vitrified-warmed blastocyst transfer (previous VBT) and a personalized vitrified-warmed blastocyst transfer (pVBT) in identical patients were compared. The details of each pVBT were further analyzed between patients in a non-displaced group, which indicated “receptive” cases in ERA results and those who were in the displaced group, which indicated “non-receptive” cases. Results: When the pregnancy rate, both per patient and per transfer cycle, of previous VBT and pVBT were compared, a significant increase in pVBT was observed between the two methods (5.3% vs. 62.8%, 4.4% vs. 47.9%, respectively). The pregnancy rates, implantation rates, and clinical pregnancy rates of the first pVBT were significantly higher in the displaced group than the non-displaced group. The cumulative ongoing pregnancy rate of the displaced group tended to be higher compared to that of the non-displaced group in the first pVBT, although the difference was not statistically significant (51.0% vs. 31.1%, [Formula: see text] = 0.06). Conclusions: Our study demonstrates that pVBT guided by ERA tests may improve pregnancy outcomes in RIF patients whose window of implantation (WOI) is displaced, and its effect may be more pronounced at the first pVBT. The displacement of WOI may be considered to be one of the causes of RIF, and its adjustment may contribute to the improvement of pregnancy outcomes in RIF patients.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91136742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatment with cabergoline suppresses cell proliferation and vascular-endothelial-growth-factor-mediated angiogenesis, thereby promoting regression of endometriotic lesions. Dienogest, a fourth-generation progestin currently in use for the treatment of endometriosis significantly decreases the volume of endometrial implants. Objective: The objective of the study was to see if cabergoline is as effective as dienogest in reducing the size of endometriomas and pelvic pain in women with endometriosis. Methods: The prospective comparative study was carried out on 56 women with endometrioma (diagnosed by ultrasound), divided by odd and even numbers into two groups. Cabergoline, 0.5 mg tablet twice weekly, was given to 28 women for 3 months. Dienogest, 2 mg tablet daily, was given to 28 women for the same duration. Pre- and post-treatment assessment of endometrioma size by transvaginal sonography and pelvic pain using the 10-cm visual analog scale (VAS) were recorded. Results: The percentage reduction in endometrioma size in women given dienogest was twice that compared to the women given cabergoline. Mean VAS score after 3 months was significantly lower in the cabergoline group compared to dienogest ([Formula: see text] ¡ 0.05). The incidence of nausea, vomiting, and headache were similar in cabergoline and dienogest group. There was polymenorrhea in the cabergoline group and irregular spotting in the dienogest group. Conclusions: Reduction of the size of endometrioma is less apparent with cabergoline than dienogest after 3 months of treatment. Cabergoline yields better results in decreasing pelvic pain compared to dienogest.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"280 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75782237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is understood about their attitudes and willingness to provide and support different procedures. Therefore, we examined fertility physicians’ perspectives on support of public funding and willingness to provide care in various scenarios. Methods: We invited fertility physicians attending the 8th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE 2018) to participate in a 10-minute survey. Participants completed the survey anonymously and in private. Results: 78 out of 105 fertility physicians from 12 countries completed the survey (response rate = 74.3%). Mean age was 44.9 years (SD = 11.1). A majority of respondents supported public funding for ART: 76.3% for intrauterine insemination and 80.5% for in vitro fertilization. For controversial procedures, a majority agreed to provide social egg freezing (88.5%) compared to sex selection (25.6%) and gene editing for nonmedical reasons (19.2%), p < 0.001 for both comparisons. Support for public funding was also significantly higher for social egg freezing (51.3%) compared to sex selection (23.1%) and gene editing for nonmedical reasons (20.5%), p < 0.001 for both comparisons. For eligibility criteria, willingness to provide treatment to single women (50.0%) was significantly higher compared to other nontraditional family structures — single men (33.3%), p < 0.001, male homosexual couples (33.3%), p = 0.002, female homosexual couples (32.1%), p = 0.001 and unmarried heterosexual couples (32.1%), p = 0.004.

Hysterosalpingography (HSG) is the radiographic evaluation of the uterus and fallopian tubes, which has been used as a first-line test for tubal assessment since 1920s. Laparoscopy is considered to be the gold standard for the diagnosis and management of tubo-peritoneal pathology. The objective of this study is to evaluate and compare the diagnostic value of both HSG and laparoscopy for assessment of tubal occlusion. Methods: This is a prospective cross-sectional study. Laparoscopic chromopertubation was conducted on 125 consecutive infertile women who attended the “Infertility Management Center” from October 2018 to September 2019. All patients had HSG performed in the radiology department of different hospitals. Laparoscopic findings were used as a reference standard to analyze the findings of HSG for tubal occlusion. Data were analyzed by SPSS software (version 16). Results: Normal HSG findings were seen in 53 patients (42.4%). Unilateral tubal occlusion was present in 38 (30.7%), and bilateral occlusion in 34 (27.2%) patients. Laparoscopy showed normal findings in 85 (68.0%) patients. Unilateral tubal occlusion was demonstrated in laparoscopy in 27 (21.6%) and bilateral tubal occlusion in 13 (10.4%) patients. HSG findings for diagnosis of tubal occlusion was true positive in 30 (24%) cases, false positive in 42 (33.6%) cases, false negative in 10 (8%) cases, and true negative in 43 (34.4%) cases in comparison to laparoscopy findings. Sensitivity of HSG was found to be 75.0%, specificity 50.6%, and accuracy 58.4%. Positive predictive value and negative predictive value were 41.7% and 81.1%, respectively. Conclusion: HSG is widely used for tubal assessment in Bangladesh as it is a relatively inexpensive, low-risk office procedure. But it has a low specificity and positive predictive value with a relatively high negative predictive value. Laparoscopy, on the other hand, is preferable when there is high suspicion of tubal pathology.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83628626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A descriptive analysis was performed on the clinical variables where data were reported. Descriptive statistics (means, frequencies, percentiles) were used to describe the occurrence of adverse gestational outcomes. Odds ratios were also calculated for perinatal outcomes. Infant characteristics and outcomes were evaluated using statistical analysis software IBM SPSS v26. Results: There were 15,417 pregnancies reported by respondents to the MEAO Census Study. Of these, 74% (11,367) resulted in a live delivery, 0.75% in a stillbirth, and 20% in another type of pregnancy loss (ectopic pregnancy, miscarriage, termination). The unadjusted odds of an adverse perinatal outcome were higher in the MEAO Census population than in the general Australian population, notably stillbirth (OR = 3.11, 95% CI 2.56–3.80), perinatal death (OR = 3.80, 95% CI 3.26–4.44), and neonatal death (OR = 5.43, 95% CI 4.27–6.91). There were 499 cases of birth defects reported and 85 cases of childhood cancer in the MEAO population. The unadjusted odds of childhood cancer were slightly higher (OR = 1.7, 95% CI 0.09–3.28) in the MEAO population, and the unadjusted odds of birth defects were lower (OR = 0.52, 95% CI 0.40–0.68). The male:female infant sex ratio of babies born to respondents was 102 (5939 males:5823 females). Conclusions: The MEAO Census Study presents a generally reassuring picture of reproductive health for women serving in the Australian Defence Force with regards to the risk of pregnancy loss and perinatal outcomes. The increased odds of perinatal and neonatal death and stillbirth are worthy of further study and evaluation, as is the increase in likelihood of childhood cancer in the offspring of MEAO veterans.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75391187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
