It sounds as though you have some very specific questions about the process of sperm collection. In this situation, answering your specific questions in the context of your medical history and the reason for the sperm collection is best done by your treating physician(s). Evaluating a sperm collection can be done for many different reasons, including as part of a fertility workup; as part of assisted reproduction with evaluation for techniques including intrauterine insemination or in vitro fertilization; or as part of the evaluation for personal or for-profit sperm banking. In each of these cases, the testing and evaluation of a sperm sample may be slightly different. In general, sperm can still be viable up to 24 hours after ejaculation, so some sperm will still be viable when evaluated several hours after collection. Morphology (shape) of the sperm is also not something that will change in just a few hours. However, during an infertility evaluation, other variables area also assessed and temperature and ph changes when delaying evaluation of a collected specimen can result in inaccurate results. Furthermore, if sperm are being collected for banking or use in assisted reproduction, minimizing the time between collection and evaluation is likely to be more successful. If you have concerns about a sample you submitted, you should definitely book an appointment with your doctor
to address those concerns.
