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.
Medical science has yet to find an exact cause-and-effect relationship between enlarged prostate (BPH) and sexual dysfunction. But a 2003 study 1 shows a significantly higher risk of sexual dysfunction among men with BPH than those without BPH and even greater risk among those men with more severe BPH symptoms.
