Modern techniques like surrogacy, sperm bank, IVF technique help human beings to have their children.
Techniques are used for having the child in case of those childless couples who suffer problems like less sperm count, obstacles in the oviduct, etc.
- In Vitro Fertilization (IVF) - In this technique, fertilization is brought about in the test-tube and the embryo formed is implanted in uterus of woman at appropriate time.
- Surrogacy - Surrogacy is another method which is used for women who face problem in implantation of embryo in uterus. In this technique the donor of the oocyte is the women itself who has problem in implanting the embryo in the uterus. The collected oocyte is fertilized with the sperm of her husband in a test tube. The embryo which is obtained after fertilization is implanted in the uterus of another female who is called the surrogate mother.
- Sperm bank - It is a new concept which is similar to blood banks. Sperms are collected from the male donors after a thorough medical checkup and stored for future use. These sperms are used to fertilize the ovum of the women and then this fertilised ovum is implanted in the uterus of the same women.
