ABSTRACT
To determine wheather endometrial sonography in the Late follicular phase could predict the success of AIH in infertile couples. The study included 46 patients with infertility due to poor semen parameters who presented at the infertility clinics of Northern Area Armed forces Hospital and Jubail General Hospital and were monitored for endometrial growth during late follicular phase till timing of AIH during 142 treatment cycles. A significant higher [P < 0.05] endometrial thickness was observed in the 18 women who conceived [9.2 +/- 0.7 mm] compared with 28 women who failed to conceive [7.1 +/- 0.6 mm] after repeated AIH trials. A thickness of more than 8 mm at the day of AIH was reported in 81 treatment cycles with pregnancy achievement in 16 cases while endometrial thickness of 6 to 8 mm was reported in 46 cases with a pregnancy occurrence of 2 cases after AIH. This difference in pregnancy rates was statistically significant No pregnancy reported in cases of AIH with endometrial thickness of 5 mm or less. A significant higher mean endometrial growth rate of 0.8 +/- 0.07 mm / day was reported in the group that achieved pregnancy compared with only 0.3 +/- 0.02 mm / day in the non-conception group. Ultrasonographic monitoring of endometrial thickness is relatively non invasive, and may improve our ability to select women who have a higher chance to conceive, following AIH and others with a less chance who may better to be postponed to another treatment cycle
