Egg sharing or oocyte sharing has different meanings: one is usage of a donor for two recipients that the recipients share the donated oocytes and compensation expenses. But the more popular definition of oocyte sharing is that an infertile woman undergoing assisted reproductive techniques gives half of her own oocytes to a recipient in return for subsidized expenses of fertility treatment. This paper focuses on the later definition and compares this procedure with oocyte donation from ethical religious social and legal perspective. The key results are as follows: oocyte sharing is more acceptable upon Islam ethically it does not put a normal and fertile young woman under risk of fertility drugs anesthesia and operations socially it reduces the danger of “oocyte business” like changing the donor to vender payment brokers arguments advertisements etc… and legally there is no difference between these two procedure and if donation is acceptable so is the sharing program. There are two major concerns about egg sharing which are as follows: 1. maybe there are some psychological effect on donors who do not succeed to have a child but the recipient does. Although this effect was not reported in many researches and donors were always happy about what they did but with complete anonymity it can be reduced. 2. There is a concern about the health of donor who is infertile and can have some health problems and advanced age which can be afforded by definition of some criteria for the suitable egg sharers.
