Review Meta Analysis
Impact of Caesarean section on subsequent fertility: a systematic review and meta-analysis.
Is there an association between a Caesarean section and subsequent fertility? ⋯ Further research is needed to reduce the impact of selection bias by indication through creating more comparable patient groups and applying risk adjustment.

Comparative Study
Endogenous thrombin potential is higher during the luteal phase than during the follicular phase of a normal menstrual cycle.
Do thrombin generation and haemostatic parameters differ during the two phases of the menstrual cycle? ⋯ The associations between progesterone and the haemostatic markers, as shown for both phases of the menstrual cycle, suggest a previously unknown or undefined yet potentially significant role for progesterone in the coagulation system. However, it has been shown that the use of progestogen-only preparations does not affect the coagulation system, which is partly the reason why they are considered safe for women with thrombophilia or previous thrombotic event. Further studies are required in order to demonstrate whether our results can be extrapolated for synthetic progestins, which might have significant implication on the indications for their use.

Comparative Study
Sexual dimorphism in adipose tissue function as evidenced by circulating adipokine concentrations in the fasting state and after an oral glucose challenge.
Do the circulating levels of a panel of adipokines involved in glucose metabolism exhibit sexual dimorphism in the fasting state and after an oral glucose load? ⋯ Sexual dimorphism in adipose tissue function should be considered when studying adiposity and obesity, and also when designing strategies for their diagnosis and management.

Do uric acid levels across the menstrual cycle show associations with endogenous estradiol (E2) and reproductive hormone concentrations in regularly menstruating women? ⋯ These findings demonstrate the importance of taking menstrual cycle phase into account when measuring uric acid in premenopausal women, and confirm the hypothesized beneficial lowering effects of endogenous E2 on uric acid levels. These findings suggest that there could be an underlying association affecting both sporadic anovulation and high uric acid levels among young, regularly menstruating women. Further studies are needed to confirm these findings and elucidate the connection between uric acid and reproductive and later cardiovascular health.

Does embryo biopsy inherent to preimplantation genetic screening (PGS) affect neurological, cognitive and behavioural development of 4-year-old children? ⋯ The need for careful long-term monitoring of children born following embryo biopsy remains, as it is still applied in the form of PGD and it is still unknown whether embryo biopsy affects long-term neurodevelopmental outcome.
