The penis is the male EXTERNAL genitalia. NCERT lists the male reproductive system as: a pair of testes, accessory ducts, accessory glands, and the external genitalia (the penis). So testes and ducts are inside, but the penis is the external part. NEET often asks you to sort organs into these groups.
The glans penis is the enlarged end (tip) of the penis. It is covered by a loose fold of skin called the foreskin. Remember the exact NCERT words: 'enlarged end = glans penis', 'loose fold of skin = foreskin'. NEET can swap these two terms to trick you.
The penis is made of special ERECTILE tissue. This tissue fills with blood and causes the erection of the penis, which helps in insemination. If a question says the penis is made of muscle or cartilage, that is wrong the correct word is erectile tissue.
The bulbourethral glands (Cowper's glands) help in the lubrication of the penis. This exact match was tested in NEET 2020. Do not confuse them with the prostate or seminal vesicles those add fructose, calcium and enzymes to seminal plasma, but the bulbourethral glands do the lubrication.
Yes. The urethra starts from the urinary bladder and extends through the penis, opening outside at the urethral meatus. The same urethra carries both urine and semen to the outside, which is why NEET may test its full path.
Match the following columns and select the correct option. Column-I: (a) Placenta (b) Zona pellucida (c) Bulbourethral Glands (d) Leydig cells. Column-II: (i) Androgens (ii) Human Chorionic Gonadotropin (hCG) (iii) Layer of the ovum (iv) Lubrication of the penis.

External. NCERT names the penis as the male external genitalia, separate from the testes, ducts and accessory glands.
The enlarged end is called the glans penis, and it is covered by a loose fold of skin called the foreskin.
The penis contains special erectile tissue. When it fills with blood, the penis becomes erect, which helps in insemination.
Insemination is the act of transferring sperm into the female reproductive tract. Erection of the penis helps this happen.
The bulbourethral glands (Cowper's glands). This was directly asked in NEET 2020.
