Manipulating Reproduction 1: Fertility Control
Current Capacity for Manipulating Reproduction:
• Fertility - contraception
• Infertility - increase in age increases infertility
• Pregnancy - monitoring foetal and maternal health
• Birth - inducing labour
• Menopause/andropause - using hormones to alleviate symptoms
• Other life processes
o Skin - acne
o Bones - osteoporosis
o Wellbeing - steroids
o Athletic performance
o Cancer
Importance of Fertility Control:
• 2/3 out of pregnancies are unintended
• Pregnancies that are too early, too late or too closely spaced have a negative
impact on maternal and child health
• Slows population growth
• Impacts on environment, resources, health, conflict
Maternal Health:
• 20% of maternal deaths attributed to unsafe abortions in 2000
• Significant decrease from 1990 and 2015 - 44% reduction
• 830 women die each day due to complications in pregnancy and childbirth
• 99% of these deaths occur in developing countries
Infant and Child Health:
• 20% of infant deaths would be avoided if all births were spaced at least 2 years
• More prominent in developing countries
• Comes down to breastfeeding - compromised nutrition
• Maternal condition has not gone back to optimum if births occur less than 2
years
• Results in low birth rate, pre-term births
Fertility Control - Population Growth:
• More people being born than are dying
• Exponential population growth
• Total fertility rate decreases if more contraception is prevalence
