The gender biases and a strong preference for male children are two patriarchal constraints in India which have restrained the growth of full potential in the country. The analysis explores the extent of use of contraceptive according to the sexual preference and its effect on family planning practices as well as it sees the variation in sex preference and contraceptive use in different categories. In this study, it has been observed son preference very strong and pervasive. It is mostly observed that couples having more surviving sons are more likely not to desire additional children. When couples have had one or more sons, they are more likely to accept contraception. Son preference has also been reported to be an important reason for the use of prenatal sex identification tests and sex-specific abortions. From the study above we can infer that there is a strong relation between son preference and contraceptive use. The preference of sons will lead to the less use of contraceptives. When there is a desire for a male baby, and if the first two baby is a girl then the use of contraceptive is low as compared to the couples who have already got their preferred sex .So here we can clearly see that there is strong sex preference and the use of contraception also depends upon people’s choices about the sex of the child they want. When the couples get the desired sex of the child, they start practicing contraceptive use.
