Prognosis of oocyte donation cycles: a prospective comparison of the in vitro fertilization-embryo transfer cycles of recipients who used shared oocytes versus those who used altruistic donors.

Objective: To prospectively compare the prognosis of IVF-ET cycles using oocyte sharing vs. cycles using altruistic donors.

Design: Prospective cohort prognostic study.

Instructions to authors for case reporting are limited: a review of a core journal list.

Background: Case reports are frequently published in the health care literature, however advice on preparing such reports using the "instructions to authors" pages of journals is alleged to be limited. However, to our knowledge, this has not been formally evaluated. As roles of case reports may vary according to the case and the clinical specialities, one might expect the advice to authors to vary according to journal clinical grouping.

Diagnostic and therapeutic value of selective salpingography and tubal catheterization in an unselected infertile population.

Objective: To present diagnostic findings and fertility outcome after selective salpingography and tubal catheterization in an unselected infertile population.

Design: Cohort study.

Setting: Tertiary reproductive medicine unit.

Long-term fertility prognosis following selective salpingography and tubal catheterization in women with proximal tubal blockage.

Background: The possibility of conception following selective salpingography and tubal catheterization is believed to decline sharply a few months after the procedure. This observation may be due to the relatively small number of patients and short follow-up of previous studies. Furthermore, couples with other causes of infertility apart from proximal tubal blockage have usually been excluded.

The effect on pregnancy rates of tubal perfusion pressure reductions achieved by guide-wire tubal catheterization.

Background: Selective salpingography enables us to measure the Fallopian tube perfusion pressure which, when high, can be effectively reduced with the use of transcervical guide-wire tubal catheterization. Whether fertility prognosis improves as a result is currently unknown. Our objective was to clarify the issue.
