1. Artificial Insemination (AI)
• injecting a sample of sperm from the male partner into the female partner's reproductive tract.
Used by.....- infertile couple (ie man with a low sperm
count)- woman without a partner who wants a child

2. In Vitro Fertilization (IVF)
– fertilization takes place outside the body in a laboratory procedure
– fertilized oocytes are implanted in the uterus
– may be used in conjunction with “in vitro maturation”

• in vitro maturation (IVM) - where primary follicles are removed and induced to mature into secondary follicles.
• IVM is used to produce numerous oocytes for IVF

• Used by....– a woman with damaged or blocked oviducts

3. Superovulation• FSH injections
• HCG (human chorionic gonadotropin) injections mimics effect of LH
Used to....
produce multiple eggs for IVF or to increase the chance of pregnancy

4. Surrogate Motherhood• Either
– a fertilized oocyte from from an infertile couple is placed in the uterus of a surrogate mother
• or– a surrogate undergoes AI using sperm from the
male of an infertile couple
Used by....
a woman who cannot bring a child to term

5. Cryopreservation
• oocytes, semen or embryo are preserved by freezing
Used by....
a male or female cancer patient who may become sterile due to radiation therapy
a sperm bank that supplies semen for AI
