In a large Australian study, researchers found that baby boys born with undescended testes had a higher risk of health problems like infertility and cancer, especially if corrective surgery was delayed.

Sanfilippo, Hanna Valli-PulaskiAbstractThe 5-year survival rate for childhood cancer is over 80%, thereby increasing the number of young women facing infertility in the future because of the gonadotoxic effects of chemotherapy and radiation. The gonadotoxic effects of childhood cancer treatment vary by the radiation regimen and the chemotherapeutic drugs utilized. Although the American Society of Clinical Oncology guidelines recommend fertility preservation for all patie...
Many survivors of childhood cancer will experience premature gonadal insufficiency or infertility as a consequence of their medical treatments. Ovarian tissue cryopreservation (OTC) remains an experimental means of fertility preservation with few reports focused on the surgical technique and postoperative outcomes for OTC in children.
ConclusionAlthough this population of women has above average knowledge scores, they still demonstrated a desire for more information on reproduction after cancer therapy. While PedsQL scores fell within a normal range, survivors report infertility would cause negative emotions.Implication for cancer survivorsThis information can be used refine educational programs within survivorship clinics to improve knowledge of post-treatment reproductive health.

AbstractAdult survivors of childhood cancers are more prone to developing poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation during childhood. Chemotherapy drugs exert cytotoxic effects systemically and therefore can damage the ovaries, leading to infertility, premature ovarian failure, and, to a lesser extent, spontaneous abortions. They have very limited or no deleterious effects on the uterus that can be recognized clinically. By contrast, radiation is detrimental to both the ovaries and the uterus, thereby causing a gr...
