Anadrol 50 might affect your testicles and sexual health in some way. It can lead to testicular atrophy (testicles get smaller) and affect your sexual drive.

You took the Levonorgestrel tablet (ifree 72) after having sex without protection. This medication is designed to prevent pregnancy within a certain time frame. It is understandable if you are anxious, but there is no need for another pill; wait until your next period starts.

Nightfall is normal. Your body's dropping off some semen while you're asleep, that’s all. It could be activated by stress, sleeping in a weird position, or thinking sex-related thoughts before bed.

If this doesn’t work after a while (like more than say three months), then maybe see a sexologist about it.

To improve your chances of getting your wife pregnant, you should address both the penis problem and asthenozoospermia. Stress, fear or health issues such as heart disease may cause the penis to malfunction. Asthenozoospermia is when a male’s sperm are not moving well. One might need advice that is tailored to them from a professional on what to do which could involve; talking therapy to reduce anxiety levels, drugs that can help one get an erection, or changing how they live intending to improve their sperm health among others. A sexologist should be consulted for more information on this subject.

It sounds like your friend might be facing some issues with sperm production and fertility. He should see a urologist, who specializes in male reproductive health.
