In what cases is ICSI commonly used?
Female factor infertility
Male factor infertility
Both female and male factor infertility
None of the above
ICSI is commonly used in cases of male factor infertility, where the male partner has low sperm counts, poor sperm motility, and poor quality of sperm to penetrate the oocyte. In such cases, conventional IVF may not be effective, and ICSI offers a higher chance of successful fertilization. In ICSI, a single sperm cell is directly injected into the cytoplasm of the ovum, bypassing any barriers to fertilization that may be present in the male partner's sperm. This technique has revolutionized the treatment of male factor infertility and has helped many couples to achieve pregnancy. Hence, option 2 is the correct answer.
