A discussion on prenatal diagnostic of gender

Prefertilization Sex selection by sperm sorting or flow cytometry enables the separation of X- from Y-chromosome-bearing sperm due to slight differences in weight whereby X and Y-bearing sperm have a DNA difference in content of approximately 2.

This study is often limited due to the fetus being much larger, with a relative decrease in surrounding amniotic fluid.

This makes imaging more challenging for the clinician. At times the cycle may be irregular or bleeding may become heavy.

This may be due to a temporary hormonal imbalance but it may also signal a problem in the uterus or ovaries such as: An Endometrial Polyp which is a small growth in the lining of the uterus. Polyps can cause heavier periods or unusual bleeding. Most polyps are not cancerous but may become so if not treated.

They can be seen on transvaginal ultrasound but sonohysterography allows easier detection. Fibroids Abdominal Pain Pain may be caused by any organ in the abdomen, and as such is often difficult to determine an exact cause without ultrasound.

Common conditions detected through ultrasound include: Discomfort with the onset of a period is normal, but severe pain may be caused by conditions such as endometriosis and cysts. Each month the ovary produces a cyst as part of the ovulation cycle.

Most disappear by the time of the next period, but sometimes they can become large and tender resulting in abdominal pain.

The bowel can cause pain which presents itself as a dull crampy feeling. It can be related to diet and stress but ultrasound can provide peace of mind of no other underlying problem. Ovarian Cancer Screening Symptoms from ovarian cancer tend to occur quite late in the disease when it is increasingly difficult to treat.

Subjects and Methods

Ultrasound can play a significant role in the detection or exclusion of ovarian cancer through colour doppler ultrasound. The examination will help identify if the ovaries are enlarged or if new blood vessels have appeared to supply a growing tumour.

Regular screening is recommended for those at increased risk: Over 50 years of age There is a history of ovarian cancer in the family Sonohysterography Sonohysterography is a new technique developed to better image the uterine cavity. It uses an infusion of sterile saline through a soft plastic catheter placed in the cervix in conjunction with transvaginal ultrasound.

The saline infusion distends the uterine cavity and provides an excellent contrast to the lining, giving improved visualisation of uterine and endometrial pathology.A Non Invasive Prenatal Test (NIPT) offers pregnant women an early, accurate and personalised option for determining the risk of carrying a fetus with common genetic conditions, including Down syndrome (T21) and Edward syndrome (T18).

Prenatal Diagnosis; Fetal gender assessment by transabdominal ultrasound was performed in singleton pregnancies at 12–14 weeks of gestation. The genital region was examined in the mid‐sagittal plane. Discussion.

INTRODUCTION

According to our results, gender assignment by ultrasound has a high accuracy rate at 12–14 weeks (% for males. Discussion. Prenatal diagnosis of fetal gender by ultrasound generally has a high rate of accuracy and is a well-established part of routine ultrasonography6.

However, when fetal genitalia appear malformed or ambiguous, or gender assigned by ultrasound does not match gender by karyotype, a plethora of syndromes must be considered and the limitations of ultrasound imaging in observing the external .
