How ICSI Works: A Guide to In Vitro Fertilization
ICSI involves injecting a single sperm into an egg during IVF to address infertility, particularly low sperm motility or count. Embryos are transferred 5-6 days post-fertilization, with pregnancy results confirmed via blood tests two weeks later.
Key Takeaways
ICSI for Male Infertility Causes
ICSI is recommended for infertility cases involving low sperm motility, count, or morphology. It bypasses natural fertilization barriers by directly injecting sperm into the egg, ensuring fertilization when sperm cannot penetrate the egg independently.
ICSI Procedure Steps Explained
The process begins with ovarian stimulation to produce multiple eggs. Eggs are retrieved under sedation while a semen sample is collected. An embryologist selects and injects the healthiest sperm into each egg in a lab setting.
ICSI Preparation Tips for Success
Patients must follow a fertility medication regimen and abstain from sex 2-3 days before egg retrieval. Consult an andrologist for personalized advice, and expect fertilization results the day after ICSI, with pregnancy confirmed via blood tests 14 days post-transfer.
