Does Judaism allow egg and sperm donations?

Judaism's stance on egg and sperm donations can vary among different denominations and communities. Generally, Orthodox Judaism may have more restrictions due to concerns about lineage and the sanctity of procreation, while Conservative and Reform Judaism tend to be more accepting of such practices. Many Jewish authorities emphasize the importance of fulfilling the commandment to be fruitful and multiply, which can lead to support for assisted reproductive technologies, including donations. However, specific guidance often depends on individual circumstances and rabbinic interpretation.
