STUDY QUESTION: What are the reproductive experiences and outcomes of people who store reproductive material before cancer treatment? SUMMARY ANSWER: Of respondents who had tried to achieve pregnancy since completing cancer treatment almost all had succeeded, in most cases through natural conception. WHAT IS KNOWN ALREADY: People of reproductive age who are diagnosed with cancer can cryopreserve reproductive material to guard against the adverse effects on fertility of gonadotoxic treatment. Little is known about the reproductive outcomes of people who undergo fertility preservation before cancer treatment. STUDY DESIGN, SIZE, DURATION: Cross-sectional survey. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women and men who had stored reproductive material before cancer treatment at two private and one public fertility clinics up to June 2014 and were at least 18 years old at the time were identified from medical records and invited to complete an anonymous questionnaire about their reproductive experiences. MAIN RESULTS AND THE ROLE OF CHANCE: Of the 870 potential respondents 302 (171 female and 131 male) returned completed questionnaires yielding a response rate of 34.5% (39.5% and 29.7% for female and male respondents, respectively). Current age was similar for women and men (37.2 years) but men had been diagnosed with cancer significantly earlier in life than women (28.2 versus 30.3 years, P = 0.03). Almost two-thirds of respondents wished to have a child or another child in the future, some of whom knew that they were unable to. One in ten respondents was a parent before the cancer diagnosis and around one-third had had a child since diagnosis or was pregnant (or a partner in pregnancy) at the time of the survey. Of those who had tried to conceive since completing cancer treatment (N = 119) 84% (79% of women and 90% of men) had had a child or were pregnant (or a partner in pregnancy). Most of the pregnancies since the diagnosis of cancer occurred after natural conce

BACKGROUND: Cancer treatment can diminish fertility in women and men. The need for fertility preservation is growing as increasing numbers of people survive cancer. Cryostorage of reproductive material to preserve potential for conception for cancer survivors has moved from being experimental to being a part of clinical management of women and men who are diagnosed with cancer in their reproductive years. There is little existing evidence about how fertility preservation services can be enhanced to meet the complex needs of patients who are diagnosed with cancer in their reproductive years. The aim of this research was to inform clinical practice development by drawing on the collective experience and knowledge of staff at well-established clinics that offer fertility preservation before cancer treatment. METHODS: A qualitative research model was adopted using semi-structured interviews with professionals involved in the care of people who freeze reproductive material before cancer treatment. In the state of Victoria, Australia, two large assisted reproductive technology (ART) centres have been providing fertility preservation services for more than two decades. An invitation to participate in a semi-structured interview about clinical care in the context of fertility preservation was emailed to past and current staff members. To capture diverse perspectives, informants were sought from all relevant professions: fertility specialists, andrologists, nurses, embryologists/scientists, counsellors, and administrative staff. Transcripts were analysed thematically. RESULTS: Thirteen key informants were interviewed from August 2013 to February 2014. The identified themes relating to enhancing clinical care in a fertility preservation service were communication between oncology and ART specialists; managing urgency; managing patients' expectations; establishing and implementing protocols, systems, and data bases; and maintaining contact with patients. CONCLUSION: The collec

Ovarian tissue cryopreservation and transplantation is a form of fertility preservation offered to young women at high risk of losing ovarian function after cancer treatment. While there have been successful births resulting from orthotopic site grafts, we report the first case of an ongoing pregnancy from a heterotopic graft in a patient who had previously undergone bilateral oopherectomy for a granulosa cell tumour. Frozen-thawed ovarian tissue was transplanted to the anterior abdominal wall. Subsequent ovarian stimulation and transabdominal ultrasound-guided oocyte retrieval from the grafts resulted in two oocytes. These were fertilized with ICSI and two embryos were transferred. Serial ultrasounds have confirmed an ongoing 26-week intrauterine twin pregnancy. Thus, this first demonstration of a pregnancy from a heterotopic graft site provides unequivocal evidence that cryopreservation preserves complete follicle development and that normal ovarian function can occur at a non-ovarian site. This provides optimism for further efforts to assist women who have had oophorectomy and pelvic surgery or radiotherapy, without an appropriate orthotopic site for grafting. © 2013 © The Author 2013.

Ovarian cryopreservation is a promising technique to preserve fertility in women with Hodgkin lymphoma (HL) treated with chemotherapy. Thus, the aim of this study was to examine harvested ovarian tissue for subclinical involvement by HL by morphology/ immunohistochemistry, and to define patient and treatment factors predictive of oocyte yield. This was a retrospective analysis of 26 ovarian tissue samples harvested for cryopreservation from women with HL. Histology, immunohistochemistry and follicle density (number mm-3) was examined. Disease status and preharvest chemotherapy details were obtained on 24 patients. The median age was 22 years (range 13-29). Seven of 24 patients had infradiaphragmatic disease at time of harvest. Nine of 20 patients had received chemotherapy preharvest (ABVD (Adriamycin, Bleomycin, Vinblastine and Dacarbazine) = 7, other regimens = 2). The seven receiving ABVD showed no difference in follicle density compared to patients not receiving treatment (n = 14); (median = 1555 vs 1620 mm3 P = 0.97). Follicle density measurement showed no correlation with patient age (R2 = 0.0001, P = 0.99). There was no evidence of HL involvement in the 26 samples examined (95% CI = 0-11%). In conclusion, subclinical involvement of HL has not been identified in ovarian tissue, even when patients have infradiaphragmatic disease. Furthermore, the quality of tissue harvested does not appear to be adversely affected by patient's age or prior ABVD chemotherapy. © 2006 Cancer Research.
