This is the person who feels stuck.
The brain is sending the signal, urging the o***y to release — but the message doesn’t land. Cycles stall. Ovulation is delayed or absent. Fertility feels held in suspension.
Luteinising Hormone (LH) is the messenger. It carries the brain’s prompt to the o***y, sparking ovulation and keeping the menstrual cycle moving.
When LH is too high, as in PCOS, the message is shouted on repeat until the o***y tunes it out. When LH is too low, the message never rises, and the cycle falls silent.
LH is not only about ovulation. It works in rhythm with FSH, oestradiol, and progesterone — synchronising the hormonal dialogue. When the message is clear, the body responds. When it’s stuck, the cycle waits.
LH matters. It is the signal that bridges brain and o***y, turning possibility into release.
