[36] [37] In one study, the peak levels after a single 50 mg dose of clomifene were 20.37 nmol/L for clomifene, 0.95 nmol/L for 4-hydroxyclomifene, and 1.15 nmol/L for 4-hydroxy-N-desethylclomiphene.

The twin reversed arterial perfusion, or T.R.A.P. sequence, results in an 'acardiac twin', a parasitic twin that fails to develop a head, arms and a heart.The parasitic twin, little more than a torso with or without legs, receives its blood supply from the host twin by means of an umbilical cord-like structure, much like a fetus in fetu, except the acardiac twin is outside the autosite's body.

Monoamniotic twins are identical or semi-identical twins that share the same amniotic sac within their mother's uterus.
