No. Ovulation typically alternates between the two ovaries each month. However, this process is not strictly predictable, and some variations can occur.  

If a woman has only one ovary—whether due to a congenital condition or surgery—ovulation will always occur from that same ovary. In such cases, the body adapts naturally to preserve the available follicles, meaning that women with a single ovary usually experience little to no impact on their fertility or the age at which menopause occurs.
