Answer
The secretions of structure A (seminal vesicle) contribute nutrients and make the semen alkaline, which helps neutralize the acidity of the female reproductive tract, thus enhancing sperm viability. Structure B (prostate gland) produces a fluid that contains enzymes and other substances that further nourish the sperm and facilitate their motility, improving the likelihood of successful fertilisation.
