The basic reason why unripe fruits have defensive chemicals is that they need to protect the seeds that are not ready to germinate. On the other hand, the seeds of the ripe fruits are ready to germinate and so they need to get spread with the help of animals and birds and so there are no defensive chemicals. These seeds spread to different places and the soils help them to germinate under suitable conditions.
The effect that will occur if the bulbourethral gland in male fails to perform its function is that the sperm will not survive the acidic conditions in the vagina.
The bulbourethral or the Cowper's gland produces watery, slightly mucoid fluid that neutralizes any acidity in the urethra that is left by the urine that passed through it, and therefore sperms are not harmed by this acidity. Additionally, the fluid helps in neutralizing the acidity in the vagina.
