In a gay couple, DNA from both males would be inserted into a "blanked" egg from a female donor and reinserted into surrogate mother to carry out the process of development. This process would eliminate the need of adoption in infertile and homosexual couples, and provide the couple with means to have a child that will physically and genetically resemble the parents.
Human cloning could also prove to be a solution to lengthy wait times and low success rates for patients of organ transplantation. According to GiftOfLife.on.ca "Currently in Ontario, there are over 1500 people on the waiting list for an organ transplant". This number could be largely reduced worldwide through the process of Therapeutic Cloning. Starting out quite similarly to adult DNA cloning, with a nucleus inserted into an empty egg. But rather than allowing the egg carry out the process of development into a child, it's growth would be stopped around the 14th day. From here, scientists would extract stem cells from the embryo and could then be grown into tissue clusters, skin grafts, or entire organs for transplantation. Shortened waiting times aside, there are still numerous benefits to Therapeutic Cloning when compared to a traditional organ transplant. In a traditional transplant, a patient could receive an organ that has already preformed its function for several decades, came from a donor with less than perfect health, or had questionable habits such as smoking or drinking. Through Therapeutic cloning the patient would have a brand new, custom grown organ, specifically for them. There would also be an almost zero percent chance of the patient's body rejecting the transplanted organ, as it would have an exact copy of the patient's DNA.
Finally, human cloning could be used to combat life-altering and life-threatening diseases. People with Parkinson, Alzheimer and cancer could see their illnesses take less and less control over their lives and what they can do.
