There is currently minimal data on fertility outcomes in premenopausal women undergoing autologous stem cell transplant (ASCT) with carmustine, etoposide, cytarabine and melphalan (BEAM) conditioning. A retrospective analysis of fertility outcomes in premenopausal females aged between 18 and 40 yr who underwent BEAM/ASCT for lymphoma between 1995 and 2011 was performed at four transplant centres. Of 41 premenopausal women who underwent BEAM conditioning, 25 met the inclusion criteria with the main exclusion criterion being inadequate documentation.

Female genital tract graft-versus-host disease (GVHD) is an under-recognized complication of allogeneic stem cell transplantation impacting on quality of life. We describe a prospective surveillance programme for female genital GVHD to better characterize incidence, risk factors and clinical features and the impact of a structured intervention policy. A retrospective audit was conducted on the medical records of all female transplant recipients surviving at least 6 months at a single centre over a 5-year period.

Aims: The major aims of the study were to compare the safety of a continuous low-dose estradiol-releasing vaginal ring (ESTring) to that of a vaginal estradiol tablet (Vagifem) on the endometrium and the relief of subjective symptoms and signs of urogenital estrogen deficiency. Quality of life and acceptability of treatment delivery were also assessed.

Study Design: A prospective, randomized study in which women were assigned in a 2:1 ratio to ESTring and Vagifem and followed for 12 months.

The aim of this study was to test the hypothesis that increased dietary intake of phytoestrogens reduces the health impact of the menopause. To test this hypothesis, a double-blind, randomized, entry-exit, cross-over study was conducted to assess the effects of three dietary manipulations--soy and linseed diets (high in phytoestrogens) and a wheat diet (low in phytoestrogens). Postmenopausal women were recruited and randomly assigned to one of the three dietary regimens.
