Step 1: Understanding the Concept: Assisted Reproductive Technologies (ART) are advanced medical procedures used to overcome specific infertility issues in either the male or female partner.
Step 2: Key Formula or Approach: Analyze the specific diagnosis (female is normal, male has low sperm count / inability to inseminate) and match it to the corresponding targeted ART procedure.
Step 3: Detailed Explanation: In this scenario, the female is perfectly normal, meaning she can ovulate, undergo fertilization naturally, and carry a pregnancy.
The core problem lies solely with the male partner, who has a low sperm count (oligospermia) and is unable to inseminate the female naturally.
Such cases are directly treated by the Artificial Insemination (AI) technique.
In AI, the semen is collected from the husband (or a healthy donor) and is artificially introduced into the vagina or uterus of the female.
While Intra Uterine Insemination (IUI) is a specific variant of AI, Artificial Insemination (AI) is the primary overarching category explicitly taught as the direct answer for "inability to inseminate or low sperm counts" in foundational biology texts. Given the general nature of the question's phrasing from the textbook, AI is the intended broader answer.
Step 4: Final Answer: The correct option is (3).
