In infertility management, intrauterine insemination is typically used to deliver sperm when?

• A. To deliver sperm directly into the uterus to coincide with ovulation
• B. To retrieve oocytes
• C. To perform surgical embryo transfer
• D. To perform natural conception without medical assistance

Answer: (A)

Intrauterine insemination places prepared sperm directly into the uterus to align with ovulation, increasing the number of sperm that reach the egg when it is released. By delivering sperm closer to the time of ovulation, this method helps overcome cervical mucus barriers and can boost fertilization chances in mild male-factor or unexplained infertility, often in cycles where ovulation is induced to create a predictable fertilization window. It does not involve retrieving eggs or transferring embryos, which are procedures used in IVF. It is also not a method for natural conception without medical assistance.
