Fertility drugs might cause a mild reaction in some patients, and may involve hot flushes, feeling

patients, ovarian torsion could be another observed side-effect. Mild pelvic discomfort arises
because the size of ovaries increases during the stimulation period.
The other side-effects of IVF during pregnancy include ectopic pregnancy and multiple births. When
an embryo develops in the fallopian tube rather than in the womb, the pregnancy is said to be an
ectopic pregnancy. Ectopic pregnancy can cause vaginal bleeding, low pregnancy hormone levels and
miscarriage. Hormone tests and scans are used to detect ectopic pregnancies and patients must call
the doctor immediately when they observe vaginal bleeding or stomach pain.
Multiple births is another risk associated with fertility treatment. Your clinician would discuss this
risk with you before the embryo transfer procedure.
