Finally, infertility may be of great concern to both male and female patients who desire future childbearing. A study of 42 women in the WGET trial, aged 14 to 46 years (mean age 35 years), found that daily oral cyclophosphamide, even when administered for less than 6 months, was associated with diminished ovarian reserve, as evidenced by decreased anti-Müllerian hormone (AMH). [63] If there is time prior to the initiation of cyclophosphamide therapy, men may wish to pursue sperm banking and women of childbearing age should consider oral contraceptives and gonadotropin-releasing hormone analogues (ie, leuprolide) to help preserve fertility.
