Final answer:
The claim that all preantral follicles will ovulate is False. Most follicles undergo atresia and only one dominant follicle usually reaches maturity and is released during ovulation.
Step-by-step explanation:
The statement that 'All preantral follicles formed will go on to ovulate' is False. During a woman's menstrual cycle, multiple follicles begin the process of development, but not all of these follicles will reach full maturity and ovulate. A select number of follicles reach the tertiary, or antral stage, but most of these will undergo a process known as atresia, which is the degeneration and reabsorption of immature ovarian follicles. Typically, one dominant follicle will proceed to full maturity and be released during ovulation, while the rest are reabsorbed.
