Hernias or surgery
Risk factors for male infertilitiy
Environmental pollutants, marijuana, cocaine, drug alcohol use, old age, impotence,
smoking
Femal infertility:
Clomid (stimulates egg production), Selective estrogen receptor modulator,
abnormalities with fallopian tubes
Mallolectomy, take away baby making area
STDS can cause infertility, important to get treatment
Risk factors for infertility:
Autoimmune disorder, eating disorder, malnutrition, diabetes, excessive exercising
(amenorrhea), obesity.
Types of treatment (fertility)
Artificial insemination put sperm into uterus or cervix with
a catheter
Poor cervical, mucus production, diminished sperm for males, not best
anatomical shape for sperm, decreased motility.
Aspirate sperm from testes:
Take sperm and match with harvested egg, even with vasectomy, artificial
insemination
NO sperm count, low sperm in ejaculate, will still aspirate
IVF: In Vitro Fertilization
Harvest eggs, fertilize them, choose to have eggs frozen, examine eggs and
sperm make sure they are compatible, then take fertilized egg and plant in uterus.
Genetic Diseases:
Figuring out what diseases are, who is most at risk
Sick Cell Anemia:Cell is not round, is crescent shape, does not allow hemoglobin into
the blood, common in African Americans
Cystic Fibrosis: More common in European ancestry, has to do with thick mucus
clogs in bronchial tree, respiratory infections.
Can lead to pulmonary failure.
Tay Sachs: fOiund in jesish ancestry, neuro degenerative disease
Pku: Phenylketonuria, test newborns for it to see if they have it if they do they
cannot breastfeed, lack of enzyme needed to metabolize protein, have to have
special formula, diet while growing up, can lead to mental and physical retardation.
Function of the placenta:
Two main functions metabolic and gas exchange, hormone production
Metabolic and gas exchange: Baby Co2 goes to mom to get rid of it, mom I
transferring oxygen and nutrients to the baby, done through diffusion.
HCG and HPL, estrogen
Progesterone: Decreases uterine contractility, also helps to facilitate
implantation
Estrogen: Stimulate uterine enlargement, and breast enlargement
HCG: Hormone goes up when pregnant, goes up during first trimester, than
rapid decline because of placenta taking over.
