Intracytoplasmic Sperm Injection (ICSI): A Review
Abstract: Intracytoplasmic sperm injection (ICSI) is a recently developing technique in the field of developmental biology. The rationale behind artificial insemination is increasing the gamete density at the site of fertilization. Since many centuries diverse pioneers added to the historical backdrop of manual sperm injection, not only in humans but even more pronounced in farm animals. The primary reason for using this technique in farm animals is to speed up the …
