A View from the past into our collective future: the oncofertility consortium vision statement.

PURPOSE: Today, male and female adult and pediatric cancer patients, individuals transitioning between gender identities, and other individuals facing health extending but fertility limiting treatments can look forward to a fertile future. This is, in part, due to the work of members associated with the Oncofertility Consortium. METHODS: The Oncofertility Consortium is an international, interdisciplinary initiative originally designed to explore the urgent unmet need associated with the reproductive future of cancer survivors. As the strategies for fertility management were invented, developed or applied, the individuals for who the program offered hope, similarly expanded. As a community of practice, Consortium participants share information in an open and rapid manner to addresses the complex health care and quality-of-life issues of cancer, transgender and other patients. To ensure that the organization remains contemporary to the needs of the community, the field designed a fully inclusive mechanism for strategic planning and here present the findings of this process. RESULTS: This interprofessional network of medical specialists, scientists, and scholars in the law, medical ethics, religious studies and other disciplines associated with human interventions, explore the relationships between health, disease, survivorship, treatment, gender and reproductive longevity. CONCLUSION: The goals are to continually integrate the best science in the service of the needs of patients and build a community of care that is ready for the challenges of the field in the future.

Barriers and Opportunities of Oncofertility Practice in Nine Developing Countries and the Emerging Oncofertility Professional Engagement Network.

PURPOSE: Oncofertility practice continues to grow in developing countries despite the lack of health care services, especially those related to cancer care. The purpose of this study is to further explore oncofertility practice in these countries and identify opportunities for field-wide coalescence. METHODS: We generated a survey to learn more about oncofertility practice in nine developing countries within our Oncofertility Consortium Global Partners Network-Mexico, Colombia, Guatemala, Argentina, Chile, Nigeria, South Africa, Saudi Arabia, and India. Their responses were collected, reviewed, and discussed. RESULTS: Surveyed centers from the nine developing countries continue to experience a similar set of common challenges, including a lack of awareness among providers and patients, cultural and religious constraints, lack of insurance coverage and funding to help to support oncofertility programs, and high out-of-pocket costs for patients. Despite these barriers, many opportunities exist and there is great potential for the future. CONCLUSION: The current need is to unify the new technologies and best practices that emerge from rural communities and developing countries with those in large metropolitan cities, both domestically (US based) and abroad, into a functional unit: the Oncofertility Professional Engagement Network. The Oncofertility Professional Engagement Network will bridge the gap between domestic and international programs to establish a strong global network in which members share resources, methodologies and experiences and further build cultural competency.

Associations of sperm DNA fragmentation with lifestyle factors and semen parameters of Saudi men and its impact on ICSI outcome.

BACKGROUND: Male factor infertility is quite common as 30-50% of infertility cases are due to sperm defects. The high sperm DNA fragmentation is one of the causes of male factor infertility. Many factors cause sperm DNA fragmentation and could be testicular or post-testicular. The purpose of this study was to assess relationships among sperm DNA fragmentation, lifestyle factors and semen values of Saudi men and to determine impact of sperm DNA fragmentation on ICSI cycle outcome. METHODS: The duration of this study was from January 2015 to June 2016. The cases with female factor infertility were excluded. In total 94 couples were selected for investigation. The study parameters were male age, body mass index, smoking, semen values, % sperm DNA fragmentation, fertilization rate and pregnancy outcome. The ICSI procedure was performed in all patients per standard protocol. The semen samples were grouped based on % sperm DNA fragmentation into < 15%, 15-30 and > 30% which corresponded to low, moderate and high sperm DNA fragmentation, respectively. RESULTS: There was no difference in ICSI outcome in low and moderate sperm DNA fragmentation, however, in high sperm DNA fragmentation no patient achieved pregnancy. In this study, 53.19% Saudi men had low, 32.98% moderate and 13.83% high DFI. Semen volume, sperm morphology and fertilization rate did not show any correlation trend with DNA fragmentation, however, sperm concentration and motility were negatively correlated in all DFI categories. The BMI was positively correlated in moderate DFI category and smoking was positively correlated with low DFI category. The age was positively correlated in moderate and high DFI categories. CONCLUSIONS: The results of this study indicated that 14% Saudi men had high DNA fragmentation. The BMI was positively correlated in moderate DFI category and smoking was positively correlated with low DFI category. The age was positively correlated in moderate and high DFI categories.

Dynamics of a Pregnancy When Two Become Four: A Case Report and Literature Review.

The incidence of pregnancies with multiple gestational sacs has increased with the use of assisted reproductive technology because more than one embryo is frequently transferred. The splitting of one or more embryos further complicates the pregnancy. Some of these complications include intrauterine fetal death, growth restriction, discordant birth weight, and preterm delivery. Monozygotic twins suffer from a few unique complications including twin-twin transfusion syndrome, twin reversed arterial perfusion sequence, and twin anemia-polycythemia sequence. Therefore, patients should be informed about the possible obstetric complications regarding monozygotic twinning after embryo transfer as poor obstetric/perinatal outcome is significantly impacted by the presence of an "extra" fetus. The etiology of monozygotic twinning is not fully understood although a few risk factors have been identified. The objective of this communication is to report successful management of a pregnancy resulting in four gestational sacs after transfer of two embryos on day-three post retrieval.

The effect of age on in vitro fertilization outcome: is too young possible?

PURPOSE: The negative correlation between fecundity and age in women has been extensively documented although data on reproductive performance in very young women is sparse. The objective of this study was to determine whether age ≤25 years has an impact on reproductive outcome in women undergoing IVF-ET. METHODS: IVF outcome in 85 infertility patients aged 19-25 years was compared to that in 69 infertility patients aged 30-35 years. Primary outcomes included fertilization rates and embryo quality. Secondary outcomes were clinical pregnancy and miscarriage rates. RESULTS: The young patients (≤25 years) demonstrated a lower fertilization rate, and reduced number of top quality embryos. Although clinical pregnancy, and implantation rates were similar to their older counterparts (30-35 years), the young women had a significantly higher miscarriage rate. CONCLUSION: Our results demonstrating poorer reproductive performance in very young patients were surprising and need further investigation.

Failed fertilization after clinical intracytoplasmic sperm injection.

Intracytoplasmic sperm injection (ICSI) has resulted in pregnancy and birth for many couples, including those with severe male factor infertility. However, even after ICSI, complete failure of fertilization occurs in 1-3% of cycles. Most cases occur due to low number of mature oocytes, failure of oocyte activation or non-availability of appropriate spermatozoa for injection. Given the significant emotional and financial involvement in assisted reproductive cycles, failure of fertilization in all mature oocytes is a distressful event. It is not predictable. Since follow-up ICSI cycles result in fertilization in 85% of cases, repeated ICSI attempts are suggested. Physicians should counsel patients experiencing repeated failure of fertilization after ICSI cycles about available options including donated oocytes/embryos, donor sperm insemination, adoption or remaining childless if these choices are not acceptable due to religious or ethical reasons. This review discusses the causes and remedies for failed fertilization after clinical ICSI.

Expression of glycodelin and cyclooxygenase-2 in human endometrial tissue following three-dimensional culture.

PROBLEM: Our previous study showed that in vitro culture of human endometrial tissue in a three-dimensional (3D) fibrin matrix could mimic the early stages of endometriosis with invasion, gland and stroma formation and sprouting of new vessels. The objective of the present study was to evaluate the expression of glycodelin (Gd) and cyclooxygenase-2 (COX-2), two angiogenic factors, to further validate the 3D culture model of endometriosis. METHOD OF STUDY: Human endometrial fragments were obtained from endometrial biopsies and placed in a 3D fibrin matrix culture. Immunohistochemistry with specific antibodies to Gd and COX-2 was used to examine endometrial epithelium and blood vessels, and 4, 6-diamidino-2-phenylindole staining was used for nuclear identification. RESULTS: Three-dimensional culture of human endometrial tissue in the fibrin matrix resulted in the proliferation of endometrial stromal cells, glandular epithelium and angiogenesis. Gd positive glandular epithelium was seen in 85% of wells with developing endometrial glands and COX-2 positive new vessels were seen in 80% of wells with angiogenesis-like structures after 4 weeks of culture. CONCLUSION: Our findings confirm that angiogenesis occurs following the culture of endometrial tissue in the 3D fibrin matrix, and suggests that Gd and COX-2 might play important roles in promoting neovascularization and cell proliferation in the establishment of endometriosis.

Complete failed fertilization after intracytoplasmic sperm injection--analysis of 10 years' data.

OBJECTIVE: To investigate incidence and causes of complete failed fertilization after intracytoplasmic sperm injection (ICSI) in a tertiary care facility. METHODS: A total of 1,779 cycles between February 1994 and December 2003 were analyzed. Study parameters were female age, infertility diagnosis, ovarian stimulation protocol, estradiol level on day of hCG administration, number of follicles, number of oocytes retrieved, number of oocytes injected, and semen parameters. RESULTS: Complete failed fertilization occurred in 23 cycles (1.29%) involving a total of 85 oocytes injected. Infertility causes among patients with failed fertilization included unexplained (43.6%), male factor (26%), presence of more than one factor (17.4%), hysterectomy (4.4%), premature ovarian failure (4.3%), and advanced age (4.3%). In 12 cycles (52%), fewer than 5 follicles were present. In three (13%) cycles, no mature (MII) oocyte was available and in 61% (14/23) fewer than 3 MII oocytes were available for ICSI. Immotile sperm was used for ICSI in 5 cycles (21.7%). The source of sperm in 17 (74%) cycles was from ejaculate, in 4 cycles from testicular aspiration (TESA), one from percutaneous epididymal sperm aspiration (PESA) and one from retrograde ejaculation. CONCLUSIONS: Our data indicate that major contributing factors to failed fertilization after intracytoplasmic sperm injection are number of MII oocytes retrieved and availability of viable sperm for injection. Although the incidence of complete failed fertilization is not remarkable, it may increase with increasing patient age and a lower number of follicles.

Duration of sexual arousal predicts semen parameters for masturbatory ejaculates.

A man's semen parameters may vary considerably from one specimen to the next, partly due to variability in the conditions under which the specimens are produced. In the present study, the relationship between the duration of preejaculatory sexual arousal and the quality of semen produced by masturbation was investigated. Twenty-five regular semen donors aged 22-44 provided a total of 292 semen specimens (median 11 per donor) over a period of 4 months. Each specimen was produced after a minimum of 3 days of ejaculatory abstinence and measures included the time taken to produce the specimen, ejaculate volume, sperm concentration, and percent motility. Linear regression revealed that, controlling for donor identity, there was a significant (t=2.13, P<.05) positive relationship between the time taken to produce a specimen and sperm concentration. We conclude that the duration of preejaculatory sexual arousal is an important predictor of ejaculate quality for specimens produced by masturbation and that variation in the duration of preejaculatory arousal may contribute to within-male fluctuations in semen parameters over time.
