Ovulation Induction

Ovulation induction can be used for women who have been diagnosed with Hypothatic Pituitary failure or women with Polycystic Ovarian Syndrome (PCO) and consequently may not be ovulating (Annovulatory). Monitoring the response to these drugs can be in the form of a blood or urine test (measuring Luteninizing Hormone). In some cases regular ultrasound scans may be offered. The aim of ovulation induction is to aid in the ovaries to produce a follicle and hopefully a mature egg. Ovulation induction may be offered in the form of the following drugs.

Clomiphene

Clomiphene or Clomid is a tablet that aids the ovaries to produce a follicle and in turn an egg. Clomid is administered on Day 2 of the menstrual cycle and continued for five days. Monitoring in the form of urinary LH testing kits or blood tests may be offered. Ideally, as recommended by the NICE guidelines, the first cycle of Clomid should be tracked and monitored to observe the individuals response to the drug. Clomid can be used in conjunction with follicular tracking to monitor the number of follicles as well as advising timed intercourse around ovulation. The couple will then be advised to start having sexual intercourse 3 times per week to optimise chances of conception.

FSH

FSH or Follicle Stimulating Hormone is used to help the ovaries produce eggs. When using FSH ultra sound scans may be offered to monitor the response and number of follicles developing. In addition FSH also thickens the lining of the uterus to aid implantation. When the follicles are a certain size approximately 16mm or above timed intercourse may be recommended. In addition an additional injection of HCG will be used.

Dominant Follicle

HCG

HCG or Human Chorionic Gonadotrophin is a drug which enables the egg to further mature. It also aids the release of the egg in the follicle. Timed intercourse will be suggested so that sperm will be present when the egg is released from the follicle, in order for fertilization to take place in the fallopian tube.
