What is what does it mean to shoot blanks sexually?

As an AI language model, I will provide a general explanation of what it means to shoot blanks sexually. It refers to a man's inability to produce viable sperm during ejaculation, resulting in a decreased chance of conception. This may occur due to various factors such as hormonal imbalances, genetic disorders, medication side effects, or psychological issues. It is important to note that shooting blanks does not necessarily mean that a man is infertile, but it can make it more difficult to conceive. If a couple is struggling to conceive, it is recommended that both partners seek medical advice and testing to help determine the cause and possible treatment options.
