The Disappearing Male (Video in Lecture 4)
Number of males (of all species such as male humans, male frogs and even male fish)
decreasing
oChemicals is causing rapid evolution
oCan cause dysfunction among the human population
Something is wrong with sexual health of human males (e.g. sperm counts/ quantity
have been cut in half over the last 50 yrs and 85% of the sperm is abnormal/ not good
quality. Also testicular cancer has doubled over the last 20 yrs)
Man-made chemicals are to be blamed; interfere w/ male hormonal system and
interfering with the sexual development of males
Over 90 million synthetic chemicals and most have not been tested on humans
Some chemicals are causing profound and permanent damage to human bodies and
some of these synthetic chemicals are more damaging to boys but this idea is not
being publicized too much (some may actually find it scary)
3 ways to determine healthy sperm volume (quantity), speed/mobility and
morphology
oIn video the McCaley couple went to many fertility treatments and it took 2
yrs to conceive. Fertility doctor did mention environmental causes could have
been reason for not so healthy sperm
Male crocodile in polluted lakes (filled with pesticides such as DDT) were tested to
discover:
oLow testosterone levels (male crocodiles were having testosterone levels
similar to girls)
Testosterone plays large role in male sexual development
oSmall penis (illustrates abnormality in low testosterone levels)
o*** signals some danger for human males***
Glands produce hormones. Hormones are the body’s messengers
Majority of chemical compounds was derived by petroleum. Many of the chemicals
are used to make plastic

Document Summary

3 ways to determine healthy sperm  volume (quantity), speed/mobility and morphology: in video the mccaley couple went to many fertility treatments and it took 2 yrs to conceive.  testosterone plays large role in male sexual development: small penis (illustrates abnormality in low testosterone levels, *** signals some danger for human males**, glands produce hormones. Hormones are the body"s messengers: majority of chemical compounds was derived by petroleum. In aamjiwnaang, a daycare place in sarnia, on there was very few boys that were there. The daycare centre had more and more girls as the years went on. Sarnia, on is known for its large number of factories (40% of canada"s chemical industry is here); the factories release lots of chemicals out into the air. I t is no longer just smoke coming out of a smoke stack. : phthalates which are used in everything such as cosmetics have caused a decrease in males.
