### output:

Hallow Dear, Fertyl-M is a Camphene citrate product. It is given to induce ovulation in women who fail to ovulate normally, but have sufficient ovarian reserve of the follicles. You are very rightly taking these tablets for day 5 to day 9 of the cycle. After day 9, you should ideally submit yourself for ovulation monitoring by ultrasonography. It has got two advantages:1. You can locate the day of egg release (ovulation). Thus, you can plan your sexual intercourse accordingly. The egg has a life of 24 hours while the sperms are active for 72 hours. Hence, from just before the day of ovulation daily or alternate days' intercourse is advised. 2. Ultrasonography will reveal at what size did the follicle ruptured to release the egg. Eggs released for the follicles between 18 mm to 21 mm size are the most healthy eggs, and they have high chance of successful pregnancy. 3. Also, ultrasonography measures the thickness of the endometrium (uterine lining) at the time of ovulation. Endometrium of 9 mm to 14 mm thickness is most conducive for implantation of the fertilized ovum. Alternatively you can locate the day of ovulation by home kit. However, it has limited advantages. Considering these facts, you can plan the days of intercourse. In short, utilize the day of ovulation and then have sex at least on alternate days for next 3 days. If you do not want to go for ovulation monitoring at all (which is not advisable), you may start the intercourse 4 days after the last tablet of Ferry and continue to have at least alternate days' intercourse for next week. I hope this helps you.
