Subcutaneously administered Menopur(R), a new highly purified human menopausal gonadotropin, causes significantly fewer injection site reactions than Repronex(R) in subjects undergoing in vitro fertilization

BACKGROUND: The safety and tolerability of a new highly purified, urine-derived human menopausal gonadotropin (hMG) preparation [Menopur(R)] was compared with a currently available hMG [Repronex (R)] in women undergoing in vitro fertilization (IVF). METHODS: This was a randomized, open-label, parallel-group, multicenter study conducted in subjects undergoing IVF. Women (N = 125), 18–39 years of age, underwent pituitary down-regulation with leuprolide acetate beginning 7 days prior to onset of menses and continuing up to the day before hCG administration. Subjects were randomized to receive subcutaneous (SC) Menopur (R) (n = 61) or Repronex (R) SC (n = 64) for a maximum of 12 days. All adverse events (AEs) were recorded and subject self-assessments of injection site reactions were recorded in a daily diary. RESULTS: Significantly fewer subjects in the Menopur (R) group reported injection site reactions (P < 0.001) compared to the Repronex (R) group. Overall, there was no statistically significant difference in the incidence of AEs between the two treatment groups. CONCLUSION: Menopur (R) SC offers a greater safety and tolerability profile compared to Repronex (R) SC

A Global Biological Conservation Horizon Scan of Issues for 2023

We present the results of our 14th horizon scan of issues we expect to influence biological conservation in the future. From an initial set of 102 topics, our global panel of 30 scientists and practitioners identified 15 issues we consider most urgent for societies worldwide to address. Issues are novel within biological conservation or represent a substantial positive or negative step-change at global or regional scales. Issues such as submerged artificial-light fisheries and accelerating upper ocean currents could have profound negative impacts on marine or coastal ecosystems. We also identified potentially positive technological advances, including energy production and storage, improved fertilisation methods and expansion of biodegradable materials. If effectively managed, these technologies could realise future benefits for biological diversity.This exercise was coordinated by the Cambridge Conservation Initiative and was funded by the Natural Environment Research Council and the RSPB.
