There is insufficient evidence to support the routine use of any particular intervention either for pituitary down regulation, ovarian stimulation or adjuvant therapy in the management of poor responders to controlled ovarian stimulation in IVF. More robust data from good quality RCTs with relevant outcomes are needed.

The cost of a live birth resulting from IVF is not different in underweight, overweight and obese class I when compared with women with normal BMI. However, due to increased obstetric complications weight loss should still be recommended prior to commencing IVF even in overweight or obese (class I) women.

Endometrial thickness and reflectivity were a5sesced by transvaginal ultrasound in both spontaneous and hyperstimulated menstrual cycles. Two groups of women with ovulatory cycles were cxamined; women in group 1 had unexplained infertility anti women in group 2 were having artificial insemination by donor because of reduced spermatogenesis: a third group (group 3) comprised women with tuba1 infertility undergoing hyperstirnulation for in-vitro EcrtiliLation. Thcrc was no ditterence in endometrial thicknesc or reflectivity between the three groups. A basic pattern of endometrial appearance common to all cycles was found, consisting of hypoechoic, isocchoic and hyperechoic images, occurring in the early follicular, late follicular and luted phases, respectively. In all three groups a positive correlation was found between proliferative phase plasma oestradiol concentration and endometrial thickness. Group 1 r = 0403, P

a face-to-face consensus development meeting, which agreed consensus definitions. A standardized approach to reporting was also developed as part of the process. Participants/Materials, Setting, Methods: Healthcare professionals, researchers, and people with fertility problems were brought together in an open and transparent process using formal consensus development methods. Main Results and the Role of Chance: Forty-four potential definitions were inventoried across four definition development initiatives, including the Harbin Consensus Conference Workshop Group and International Committee for Monitoring Assisted Reproductive Technologies, 12 clinical practice guidelines, and Cochrane Gynaecology and Fertility Group guidelines. Twenty-seven participants, from 11 countries, contributed to the consensus development meeting. Consensus definitions were successfully developed for all core outcomes. Specific recommendations were made to improve reporting. Limitations, Reasons for Caution: We used consensus development methods, which have inherent limitations. There was limited representation from low-and middle-income countries. Wider Implications of the Findings: A minimum data set should assist researchers in populating protocols, case report forms, and other data collection tools. The generic reporting table should provide clear guidance to researchers and improve the reporting of their results within journal publications and conference presentations.

Spontaneous activity level was measured in rotifers of the species Asplanchna brightwelli on each day of their 5-day life span. No correlation was seen in group data between activity level and life span. However, data from individuals showed a positive correlation between life span and activity level in the latter half of the life span on 3 days out of 5. This tendency toward greater activity in the longer-lived rotifers is not consistent with the rate of living theory of aging.
