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 is very common as men age. Symptoms of prostate enlargement usually develop around age 50. By age 60, most men have some degree of BPH. At age 85, men have a 90% chance of having urination problems caused by BPH.
