Understanding Reproductive Technologies for Overcoming Conception Challenges

Reproductive technologies play a vital role in addressing conception difficulties, whether due to insufficient sperm production in males, blocked oviducts in females, or hormonal imbalances. Various methods, such as fertility drugs to stimulate egg release, artificial insemination for low sperm counts, and in vitro fertilization (IVF) for creating embryos outside the womb, offer hope to aspiring parents. While these procedures encourage successful pregnancies, misconceptions about their simplicity and success rates linger, highlighting the complexities involved.

  1. Chapter 4: Human Reproduction • 4.7 – Reproductive Technologies

  2. Reasons for conception troubles • Man might not produce enough healthy sperm • Oviducts f woman may be blocked • One ovary might not be properly functioning • Hormones might not be in proper amounts in woman’s body • So, there are technologies to help!

  3. Fertility Drugs • These drugs help woman’s body to release more eggs because of hormones. • More eggs released means a greater likelihood of getting pregnant. • Often results in twins, triplets…

  4. Artificial Insemination • Usually a medical procedure where sperm is introduced into female’s reproductive tract. • Why do this? • If male has low sperm count, sperm can be collected over time and then used. • If male produces no sperm, can use donor sperm from sperm bank

  5. Intrauterine Insemination • Similar to artificial insemination, but sperm placed into uterus, not vagina. • More effective in that more sperm will survive to reach the egg. (shorter distance)

  6. Gamete Intrafallopian Transfer • GIFT • Female’s eggs removed from ovary and reinserted into oviduct with sperm. • Oviduct is the place of fertilization therefore, increased chance of fertilization

  7. In Vitro Fertilization • IVF – fertilization takes place in petri dish in a lab • “test-tube babies” • How? • Follicles of immature eggs removed and allowed to mature • Sperm cells from father added once eggs are mature • Embryos then inserted back into mother at correct time in cycle. Several embryos means possibility of multiple births.

  8. In Vitro Fertilization • If mother cannot accept embryos for whatever reason, a surrogate mother can be used.

  9. Intracytoplasmic Sperm Injection • ICSI • One sperm inserted directly into a mature egg • Used when IVF not effective

  10. Misconception • Test-tube babies are an easy way to have children • These technologies are very successful • Infertility usually fault of female

  11. Misconception • These tests take lots of planning, monitoring (cycles), need to take drugs at certain times, • Only a 15%-20% success rate • Statistically: 50% due to female, 50% due to male

  12. Practice • CYU 4.7 – p136 #8 (may need book) 11, 12, 14, 16
