Human blastocysts should hatch from the shell and begin to implant 1-2 days after day 5 IVF blastocyst transfer. In a natural situation (not IVF), the blastocyst should hatch and implant at the same time-about 6 to 10 days after ovulation.
Enlargement of the prostate-- benign prostatic hyperplasia or BPH--is a common condition in older men that typically results in a narrowing of the urethra. BPH often makes urination difficult and sometimes painful. In addition, BPH and its associated treatments sometimes results in adverse sexual side effects.
Prostate enlargement (benign prostatic hyperplasia, which is not the same as prostate cancer) often causes pain during erection or ejaculation. Spasms of the pelvic muscles or the pelvic floor can cause post-ejaculatory pain. Kegel exercises can help relieve this problem.
