The follicles usually survive for 24 to 48 hours after discharge, and individual follicles may survive for up to 36 hours, depending on the individual.
After the follicle matures, due to changes in hormone levels in the body and the role of the ovarian surface tension, the follicle will rupture and be discharged. The discharged egg waits for fertilization in the juxtaposition of the fallopian tubes, and generally survives for 24 to 48 hours, and if it is able to encounter sperm at this stage, it will probably form a fertilized egg, and if it is not able to meet the sperm, it will be absorbed on its own.
Women with fertility requirements should arrange intercourse after the mature follicle is discharged. The fertilizing ability is stronger in the 6 to 24 hours after the follicle is discharged, and the chances of getting pregnant after intercourse are also higher.
Women can go to the hospital to have their follicles monitored by ultrasound to see the size of the follicles and how they are being discharged before deciding when to have intercourse.
