A standard test of a man’s semen to check the number and shape of his sperm and their motility.
The main agents of male reproduction that are produced in the testes and released into semen.
Sperm donation is a modern reproductive method used to overcome the unfortunate situation when functional male reproductive cells are lacking. IUI or an IVF treatment is usually applied after the selection of the donor’s sperm. These situations can differ greatly, but sometimes couples simply cannot become pregnant with the male partner’s own sperm for a myriad of reasons, including genetic or mechanical obstacles or chemotherapy damage. Lesbian couples or single women can also use sperm from a donor to complete fertilization.
Surrogacy is an arrangement, often supported by a legal agreement, whereby a woman (the surrogate mother) agrees to become pregnant and give birth to a child for another person(s) who is or will become the parent(s) of the child.
