Fix the passive tense.
for example:
I was able to take -> I took
The paper will read much better.
Also, using a slash is too informal in this sentence:
This paper sparked my interest in neuroendocrinology/sexuality.
A slash doesn't connect the two words. Instead, say something like:
This paper sparked my interest in the intersection between neuroendocrinology and sexuality.
Also, "sparked my interest" is a colloquial term and should probably be avoided in this type of writing:
This paper intrigued me to examine the intersection between neuroendocrinology and sexuality.
You get the idea.
