Because the tube is a hollow viscus, Erez and colleagues82 suggested a staging scheme based on the relationship of the tumor to the histologic layers of the tubal wall. The importance of muscularis invasion and extratubal extension brought forth a staging scheme modeled after the Dukes ...
The mature human ovum possesses a number of surrounding layers that must be penetrated by the spermatozoa for normal fertilization to occur. To assist with this task, the spermatozoa has a caplike region called the acrosome covering the anterior 80% of its head. This structure contains a numbe...
In patients in whom no disease exists and medical therapy has been unsuccessful, or when the patient is a poor surgical candidate, endometrial ablation is another alternative therapy.
