FSH and inhibin in the patient with 1 testicle(Sertoli cells are present within the seminiferous tubules of the testes.)
In patients with 1 testicle, the mass of Sertoli cells is significantly reduced. Therefore, the circulating ☆levels of inhibin B are likely to be low in these patients. Low inhibin B levels will not provide adequate negative feedback on FSH secretion, thus ☆FSH levels will tend to be elevated in males who only have 1 testicle. reproductiveUWorld Feb 24, 2020, 2:16 AM HirotoShishido
thracentesis
locationThoracentesis is typically performed between
①the 6th and 8th ribs along the midclavicular line,
②☆the 8th and 10th ribs along the midaxillary line (above image),
③and the 10th and 12th ribs along the paravertebral line.
This allows pleural fluid to be drained without risking lung injury (which can occur at higher insertion sites). However, insertion of a needle ☆below the 9th rib still risks penetrating abdominal structures. surgeryUWorld Mar 22, 2020, 10:28 AM HirotoShishido
