REPRODUCTIVE TECHNOLOGIES By Tiffany Crain & Rosemary Hébert
OVERVIEW • Infertility and Subfertility - Male Infertility - Female Infertility - Infertility Tests • Assisted Reproductive Technologies - Donated Sperm – Intrauterine Insemination - A Donated Uterus – Surrogate Motherhood - In Vitro Fertilization - Gamete and Zygote Intrafallopian Transfer - Oocyte Banking and Donation • Extra Embryos - Preimplantation Genetic Diagnosis • Quiz • References
INFERTILITY & SUBFERTILITY • Infertility is the inability to conceive a child after a year of frequent intercourse without contraceptives. • Subfertility means the couple can conceive but it takes longer. • 30% M, 60% F • 1:6 couples has difficulty conceiving children
MALE INFERTILITY • Easier to detect but harder to treat than female infertility. • 1:25 men is infertile. Causes: • <120 million sperm • Hormone imbalance • IgA antibodies cover sperm • Varicose vein on the scrotum • Sperm quality and motility
FEMALE INFERTILITY • Erratic ovulation • Blocked uterine tubes • Endometriosis • Pituitary or ovary tumors • Pelvic inflammatory disease • Antisperm secretions • Age
INFERTILITY TESTS • Males are tested first; sperm are checked for number, motility, and morphology. • Women are examined to see if reproductive structures are functioning.
ASSISTED REPRODUCTIVE TECHNOLOGIES (ARTs) • From non-donor, donor, fresh or frozen • In the US, 1:4 million births are from ARTs • 0.4% of single and 16% of multiple births
DONATED SPERM(INTRAUTERINE INSEMINATION) • Doctor puts donated sperm in woman • $125 or $3,000 if woman needs fertility assistance • Seminal fluid washed from sperm • Donor selection possible
A DONATED UTERUS (SURROGATE MOTHERHOOD) • A surrogate can carry a baby • She can also be the biological mother
IN VITRO FERTILIZATION (IVF) • “Fertilization in a glass” • Intracytoplasmic sperm injection (ICSI) • $6,500-$15,000 per attempt at a 29% success rate • Problems of passing on infertility
IN VITRO FERTILIZATION • IVF embryos can be stored in liquid nitrogen and thawed for later use.
GAMETE INTRAFALLOPIAN TRANSFER (GIFT) • Several oocytes are removed & the man gives a sperm sample • Sperm and oocytes are deposited together in the woman’s body where fertilization will take place • The sperm and the oocytes are deposited past any obstruction that might be blocking traditional methods of fertilization
WHAT TO DO WITH THE EXTRA EMBRYOS • Store them • Discard them • Donate for research • Donate to other infertile couples
QUIZ • What’s the difference between GIFT and ZIFT? • Who is checked first males or females? Why? • What’s the difference between infertility and subfertility? • According to the table provided which form/s of ART has the highest success rate? Why might this be? • Based on the information presented if you had fertility problems which reproductive technology would you choose?
