D. in-vitro fertilization

In Vitro Fertilization (IVF) is the technique by which the encounter of the two gametes, female and male, occurs to give rise to an embryo. The female female gamete is obtained by follicular puncture, prior ovarian stimulation and the male can be obtained by masturbation or testicular biopsy.
