Institute for Reproductive Health and Contraception (IRHC)

About IRHC

The Institute for Reproductive Health and Contraception (IRHC) is a research institute dedicated to male reproductive health and non-hormonal male contraceptives. We focus on understanding men's fertility at the molecular and cellular level and conducting research to develop safe, effective, and reversible contraceptive solutions.

Our mission extends beyond individual reproductive choice. We aim to promote gender equity in contraception, contribute to sustainable population management, and address global health challenges related to male fertility.

Why Non-hormonal Male Contraception?

Global Unmet Needs in Male Contraception

Currently, male contraceptive options are limited to condoms and vasectomy. Condoms can fail, and vasectomy is often irreversible. There is a pressing need for reversible, non-hormonal male contraceptives that are reliable, safe, and accessible worldwide.

Enhancing Gender Equity

Men have traditionally borne limited responsibility for contraception. Providing effective contraceptive options for men enables shared reproductive responsibility, fostering equality at home and in society.

Impact on Public Health and Fertility Management

Expanding male contraceptive choices improves reproductive autonomy and helps achieve public health goals and Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-being) and SDG 5 (Gender Equality).

Our Research

Fundamental Studies in Male Reproductive Biology

IRHC investigates the molecular mechanisms controlling male fertility and identifies targets for novel contraceptive interventions. This includes studies on spermatogenesis, epididymal function, and hormone-independent regulatory pathways.

Applied Research: Non-hormonal Male Contraceptives

Translating basic science into practical solutions, IRHC develops non-hormonal male contraceptive technologies that offer reversible fertility control for men while minimizing systemic side effects.
