Objective: To evaluate whether an unexpected poor response (cases with ≤3 oocytes) leads to a reduction in the pregnancy rate in IVF cycles compared to a suboptimal response (controls with 4-9 oocytes) in women with adequate ovarian reserve.
Methods: A nested case-control study performed in a retrospective cohort of couples undergoing IVF at the Infertility Unit of the ASST Lariana. Cases and controls had adequate ovarian reserve and were matched 1:1 for female age and number of previous cycles.
Background: According to several laboratory protocols and specific conditions, fertilization (IVF) dishes with culture media can be prepared 24 in advance compared to routine protocols. However, it is not clear if this procedure can affect embryological outcomes.
Methods: A nested case-control study was done in a cohort of couples undergoing IVF at the Infertility Unit of the ASST Lariana from August 2016 to July 2018.
