The patients' role in assessing health care quality is increasingly recognized. Measuring patients' specific experiences and needs generates concrete information for care improvement, whereas satisfaction surveys only give an overoptimistic, undifferentiating picture. Therefore, this study aimed to investigate possible weaknesses, strengths and needs in fertility care by measuring patients' specific experiences. ⋯ Infertile couples experience strengths, but also many weaknesses and needs in current fertility care. Lack of patient centredness seems to be a major cause herein. Using mixed methods is a sensitive means for identifying these weaknesses and needs.

Controlled Clinical Trial
Letrozole combined with norethisterone acetate compared with norethisterone acetate alone in the treatment of pain symptoms caused by endometriosis.
The available data on effectiveness of aromatase inhibitors in treating pain symptoms related to endometriosis is limited. We compared the efficacy and tolerability of the aromatase inhibitor letrozole combined with norethisterone acetate versus norethisterone acetate alone in treating pain symptoms. ⋯ The combination drug regimen was more effective in reducing pain and deep dyspareunia than norethisterone acetate; however, letrozole caused a higher incidence of adverse effects, cost more and did not improve patients' satisfaction or influence recurrence of pain.

Changes in the state of energy balance owing to changes in physical activity may affect the reproductive system. We evaluated the association between physical activity (PA) and fertility and parity in healthy women. ⋯ Increased risk of infertility was only found for the small group of women reporting the highest levels of intensity and frequency of PA. Awareness of the possible risks of infertility should be highlighted among non-athletic women who exercise vigorously.

In 2003, we reported an increased risk of retinoblastoma in children conceived by IVF between 1995 and 2002. However, population-based studies among children conceived by IVF did not find an elevated risk of retinoblastoma. ⋯ We found a significantly increased risk of retinoblastoma in children conceived by IVF in the total study period 1995-2007. However, this increased risk was mostly based on the much stronger risk increase observed previously, for 1995-2002. Caution and awareness on the one hand and avoiding unnecessary worries on the other hand are important at this stage of our knowledge.

Cervical ripening during pregnancy resembles an inflammatory process. Matrix metalloproteinases (MMPs), particularly MMP-8, have been linked to inflammatory processes. We studied the concentrations of, and factors associated with, MMP-8 in the lower genital tract fluids in the first and second trimesters. ⋯ MMP-8 concentrations were lower in vaginal samples than in cervical samples, and no difference was found between the first and second trimesters. Multiparity, BV and an elevated leukocyte count in the vagina were associated with increased MMP-8 concentrations. Sexual intercourse had an opposite effect. The study suggests that MMP-8 is a physiologic constituent in lower genital tract fluids, where it may be involved in host response to inflammatory and infectious processes.
