Whether to opt for surrogacy is a personal choice. But often underlying physical and emotional conditions are a determining factor here. Here are some reasons when couples decide to opt for surrogacy-
A lot of women have an inherent fear of losing their body shape or types after having a baby. The entire ordeal of having a baby, the pain of natural birth and other similar reasons could be affecting them mentally. For millions of women this may sound weird, but this is a personal decision and out of this emotional fear, some women do decide to opt for surrogacy.
In some cases, like gay couples, it is not biologically possible to have a baby. But some couples do want to have their offspring. In such cases, surrogacy is a boon because you can give your sperm and have an offspring with your genes. It is a viable option for such couples.
Medical factors of course are the primary reason that couples opt for surrogacy. Due to chronic medical conditions, infertility, unfriendly womb conditions, constant miscarriages, etc. a lot of people prefer option for surrogacy. In particular, if having a baby leads to complications for the mother - couples prefer using their eggs and sperms, which is then injected into the surrogate mother. So, though a third-person is being the host to the baby, the genes of the child comes from the biological parents. This is also known as gestational surrogacy.
