With reference to both religious and ethical views, explain the arguments for human surrogacy. 
Surrogacy is when a woman carries a child on behalf of someone else. There are four broad types of surrogacy: partial, full, commercial and voluntary. Partial surrogacy occurs when the surrogate mother provides her egg which is fertilised either in vitro and placed through artificial insemination into the womb or she is artificially inseminated by the intended father’s sperm. Only in very rare cases would sexual intercourse take place. Full surrogacy occurs when the intended parents provide egg and sperm. In some cases a donor sperm/egg may be used. Commercial surrogacy refers to arrangements whereby a woman is contracted and paid to be a surrogate mother and to deliver a baby to the intended parents; in many countries this is illegal. Voluntary or altruistic surrogacy refers to a surrogate arrangement where the surrogate mother voluntarily offers to bear a child for another couple but not for commercial gain. Surrogacy of any kind raises many religious and ethical issues. In examining reasons why people may be in favour of surrogacy, a good place to start is the Christian view.
