What is the primary purpose of artificial insemination?

1. The extraction of eggs for fertilization

2. The medical procedure of injecting semen into the uterus

3. The assessment of fertility levels

4. The natural mating of animals

The correct answer is: The medical procedure of injecting semen into the uterus

The primary purpose of artificial insemination is to facilitate reproduction by directly introducing semen into the uterus, enhancing the likelihood of fertilization. This technique is particularly valuable in both human and animal breeding as it allows for the selection of high-quality sperm from desirable males and can be used when natural mating is not possible or practical. The method enables various advantages, including the ability to preserve genetic material for future use and improve herd or species quality through selective breeding. Additionally, it can overcome challenges such as low sperm count in males and increase reproductive success rates. Other options refer to different concepts in reproduction. The extraction of eggs is related to in vitro fertilization, rather than artificial insemination. Assessing fertility levels does not involve the act of insemination; it focuses on evaluating reproductive health. Lastly, natural mating encompasses traditional reproduction strategies without the use of medical interventions like artificial insemination.
