Contraception for the year 2020

Area of Science:

• Reproductive biology
• Molecular endocrinology
• Gene regulation

Background:

• The post-HIV era necessitates advanced fertility control methods.
• Current methods like contraception and abortion have limitations.
• Existing hormonal contraceptives have broader health implications.

Purpose of the Study:

• To explore novel molecular targets for human fertility regulation.
• To examine mechanisms for precise and reversible fertility control.
• To predict future trends in reproductive health and contraception.

Main Methods:

• Analysis of regulatory peptides and their genes.
• Targeting gonadotrophin genes and circulating gonadotrophins.
• Neutralizing human chorionic gonadotropin (hCG) and pregnancy recognition signals.
• Interfering with sperm-oocyte recognition and fusion via disintegrin-integrin pathways.
• Considering vaccination and somatic gene therapy.

Main Results:

• Three distinct mechanisms for fertility regulation are proposed, increasing in specificity.
• Potential for molecular interception of sperm-oocyte interactions for reversible sterilization.
• Prediction of a shift from current methods to molecularly targeted approaches by 2020.
• Continued role for contraceptive steroids in targeted healthcare, including breast cancer and osteoporosis management.

Conclusions:

• Molecular interception of key reproductive events offers precise fertility regulation.
• Reversible sterilization based on molecular targets is a future possibility.
• Contraceptive strategies will evolve towards personalized healthcare and enhanced well-being.
