Inguinal canal of the abdominal wall, thereby bypassing the inguinal canal, is known as a direct inguinal hernia. In males with strong presentation of the cremasteric reflex, the testes can—during supine sexual activity or manual manipulation—partially or fully retract into the inguinal canal for a short period of time. In juveniles and adults with inguinal injury, retraction can be prolonged and potentially lead to overheating-related infertility. ^ Adam Mitchell; Drake, Richard; Gray, Henry David; Wayne Vogl (2010).

Femoral sheath Femoral sheath The femoral sheath (crural sheath) is formed by a prolongation downward, behind the inguinal ligament, of the abdominal fascia, the transverse fascia being continued down in front of the femoral vessels and the iliac fascia behind them. The femoral sheath is contained within the femoral triangle. The sheath assumes the form of a short funnel, the wide end of which is directed upward, while the lower, narrow end fuses with the fascial investment of the vessels, about 4 cm. below the inguinal ligament. It is strengthened in front by a band termed the iliopubic tract. The lateral wall
