Dr Anand Kumar has to his credit major contribution in the area of neuro-endocrinology of primate reproduction. He has demonstrated the presence of gonadal hormones in the cerebro-spinal fluid (csf) and their transport to the brain. His work on fertility regulation, especially the administration of contraceptive steroids through the nasal route which results in their preferential transfer into the csf, is of distinct advantage in developing newer approaches to contraception.
