Effects of medical therapy, alcohol, smoking, and endocrine disruptors on male infertility.

Rev Hosp Clin Fac Med Sao Paulo 2004 Dec 11;59(6):375-82. Epub 2005 Jan 11.

Department of Urology, Hospital das Clínicas, Faculty of Medicine, University os São PAulo, São Paulo, SP, Brazil.

Infertility affects up to 15% of the sexually active population, and in 50% of cases, a male factor is involved, either as a primary problem or in combination with a problem in the female partner. Because many commonly encountered drugs and medications can have a detrimental effect on male fertility, the medical evaluation should include a discussion regarding the use of recreational and illicit drugs, medications, and other substances that may impair fertility. With the knowledge of which drugs and medications may be detrimental to fertility, it may be possible to modify medication regimens or convince a patient to modify habits to decrease adverse effects on fertility and improve the chances of achieving a successful pregnancy.

The best infertility treatment for vasectomized men: assisted reproduction or vasectomy reversal?

Rev Hosp Clin Fac Med Sao Paulo 2004 Oct 29;59(5):312-5. Epub 2004 Oct 29.

Department of Urology, Hospital das Clínicas, Faculty of Medicine, University of São Paulo - São Paulo/SP, Brazil.

In men with prior vasectomy, microsurgical reconstruction of the reproductive tract is more cost-effective than sperm retrieval with in vitro fertilization and intracytoplasmic sperm injection if the obstructive interval is less than 15 years and no female fertility risk factors are present. If epididymal obstruction is detected or advanced female age is present, the decision to use either microsurgical reconstruction or sperm retrieval with in vitro fertilization and intracytoplasmic sperm injection should be individualized. Sperm retrieval with in vitro fertilization and intracytoplasmic sperm injection is preferred to surgical treatment when female factors requiring in vitro fertilization are present or when the chance for success with sperm retrieval and intracytoplasmic sperm injection exceeds the chance for success with surgical treatment.
