Infertility
Explores the causes of inability to conceive or produce children and various assisted reproductive technologies (ART) to overcome it.
What is Infertility?
The inability of a sexually active, non-contracepting couple to achieve pregnancy within one year.
Key points
- Define infertility and its prevalence.
- Identify common causes of infertility in males and females.
- Describe the diagnostic approaches for infertility.
- Explain the principles and procedures of various ARTs like IVF, GIFT, ZIFT, and IUI.
Common exam trap
Confusing infertility with sterility (complete inability to reproduce).
Definitions
- Term
Infertility
- Meaning
The inability of a sexually active, non-contracepting couple to achieve pregnancy within one year.
- Term
Assisted Reproductive Technologies (ART)
- Meaning
A group of medical procedures used to treat infertility, involving the handling of human gametes or embryos.
- Term
In Vitro Fertilization (IVF)
- Meaning
A process where an egg is combined with sperm outside the body, in a laboratory dish ('in vitro'). The resulting embryo is then transferred to the woman's uterus.
- Term
Gamete Intrafallopian Transfer (GIFT)
- Meaning
A procedure where eggs and sperm are collected and then immediately transferred into the woman's fallopian tube, allowing fertilization to occur naturally within the body.
- Term
Zygote Intrafallopian Transfer (ZIFT)
- Meaning
A procedure where eggs are fertilized by sperm in a laboratory, and the resulting zygote (early embryo) is then transferred into the woman's fallopian tube.
- Term
Intrauterine Insemination (IUI)
- Meaning
A procedure where specially prepared sperm are placed directly into a woman's uterus around the time of ovulation.
