The word "sterile" can function as both an adjective and a noun. As an adjective, it describes something that is free from bacteria or germs. As a noun, it refers to a person or animal that is unable to produce offspring.
A man may be called "sterile" if he is unable to father children due to a lack of viable sperm or other reproductive issues. This condition can result from various factors, including genetic abnormalities, hormonal imbalances, medical conditions, or environmental influences. Sterility is often diagnosed through semen analysis and can sometimes be treated, depending on the underlying cause.
A sterile organism is unable to reproduce or produce offspring. This can be due to factors such as genetic abnormalities, physical deformities, or other conditions that prevent normal reproduction.

The odds of being sterile vary widely depending on several factors, including age, gender, health conditions, and lifestyle choices. In general, male sterility affects about 7-10% of men, while female infertility ranges from 10-15% of couples trying to conceive. Additionally, factors like environmental exposures, medical history, and genetic predispositions can influence these odds. It's best to consult a healthcare professional for personalized assessments.
Men and women can become sterile due to a variety of factors, including genetic abnormalities, hormonal imbalances, age, and certain medical conditions. In men, issues such as low sperm production, blockages, or hormonal disorders can lead to infertility. For women, conditions like polycystic ovary syndrome (PCOS), endometriosis, or age-related decline in egg quality can result in sterility. Environmental factors, lifestyle choices, and exposure to toxins can also contribute to fertility issues in both genders.
Worker bees are female bees who are sterile. They are sterile because they have no need to breed and are not sexually mature. In order to become a queen bee, a female is selected by the worker bees and fed a special diet to make her sexually mature.

If a sterile field becomes "contaminated" with a sterile solution, the field remains sterile.

No, twin heifers born from a cow are not necessarily sterile. Twinning in cattle can sometimes result in one of the twins being sterile due to fertility issues, but it is not a guarantee for all cases. It would depend on various factors such as genetics, health, and individual development.
Male sterile pollen is primarily used in plant breeding programs to facilitate hybridization without the risk of self-pollination. By utilizing male sterile plants, breeders can ensure that only pollen from a desired male parent fertilizes the female parent, resulting in hybrid offspring with improved traits. This technique is particularly useful in crops like corn and various fruits, enhancing yield, disease resistance, and other desirable characteristics. Additionally, male sterile pollen can help maintain genetic diversity in plant populations.
