Transabdominal ultrasound involves scanning through your lower abdomen.
Transabdominal ultrasound usually provides an overview of the pelvis rather than detailed images.
However, data show that 6-10% of women who are fertile demonstrate an inadequate luteal phase, which confirms the need for a better understanding of normal variations in the menstrual cycle and in variations that could be pathologic.
This article addresses healthy menstrual physiology, the proposed pathophysiology of LPD, current methods available for diagnosis and treatment, and reasons for the controversy surrounding this subject.
Endometrial function test may be the most efficient way to directly assess endometrial receptivity prior to undergoing expensive ART procedures as it can identify unreceptive endometrium.
Pinopodes, are morphological markers of endometrial receptivity, which persist for 24 to 48 hours between days 19 and 21 of the cycle.
Integrins are the best markers of endometrial receptivity.
Most interest has been focused on the av β 3 integrin since it appears in endometrial glands and luminal surface on D20-21.
The transabdominal assessment is particularly helpful for the examination of large pelvic masses extending into the abdomen, which are not always well viewed with transvaginal ultrasound.
A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel.
The gel helps improve contact between the probe and your skin. It involves scanning with the ultrasound probe lying in the vagina.
Transvaginal ultrasound usually produces better and clearer images of the female pelvic organs, because the ultrasound probe lies closer to these structures.
The endometrium is typically biopsied because of abnormal bleeding.
