Reproductive Health Research

Reproductive health research in CDRI focuses on female and male contraception and infertility, spermicides with anti-STI properties, agents for the management of osteoporosis, uterine & prostatic hyperplasia, endometriosis and polycystic ovarian syndrome.

Global population is projected to rise exponentially from the current ~7.3 billion to 9.7 billion in 2050. Indian population, which contributes to 18% of present world population, is expected to touch 1389 million in 2020. According to the World Health Organization, the family planning needs of more than 120 million couples goes unmet every year resulting in an annual abortion rate of ~46 million. On the other hand, curable sexually transmitted infections, which increase the risk of contracting viral STDs and HIV, are a major health problem in developing countries like India. Conversely, infertility affects about 50 million (15%) couples worldwide, and India shares a high percentage of these infertile couples whose population has increased significantly over the last several years. Childlessness has serious demographic, social, personal and emotional issues. In addition, given increased longevity, endocrine disorders including osteoporosis, uterine and prostatic hyperplasia, occur more frequently. In India, 1 out of 8 males and 1 out of 3 females suffers from osteoporosis, making India one of the largest affected countries in the world. The overall objectives of the program are to design and synthesize novel molecules/isolate from natural sources and bio-evaluate them for generating new leads and to develop them as female or male contraceptives, spermicides with anti-STI properties, agents for the management of infertility, osteoporosis, uterine and prostatic hyperplasia, evaluate traditional remedies for infertility management and endocrine disorders, understand mode of action of promising agents and undertake basic research to generate new knowledge on male and female reproductive endocrinology relevant to fertility regulation and endocrine disorders.


Objective: To generate new knowledge on male and female reproductive endocrinology relevant to fertility regulation and endocrine disorders due to menopause and andropause.
