levetiracetam and Infertility--Male

The aim of the study was to assess whether, male patients with epilepsy, switching from valproic acid (VPA) to levetiracetam (LEV) or lamotrigine (LMG) critically improves sperm counts and parameters, increasing chance of patients' female partners to spontaneously conceive.. This is an observational prospective study recruiting all consecutive infertile male patients with epilepsy followed up at the outpatient Epilepsy Clinic of University Hospital of Ioannina, Northwest Greece. Infertile couples were referred to the Laboratory of Assisted Reproduction and Treatment of the University Hospital of Ioannina to conduct semen analysis. The first sample was collected while the patients were receiving VPA, and the second semen sample was collected after the patients were switched to LEV or LMG.. Seventeen infertile male patients were recruited in the study. Nine patients were switched to LEV, and eight patients were switched to LMG. The mean sperm count increased after VPA withdraw P = .06. Motility was improved with an increase of total motility and non-progressive motility (P = .02 and P = .03, accordingly), whether sperm defects were decreased, mainly head defects (P = .03). Differences between patients switched to LEV or LMG were minimal and showed no significant findings. Spontaneous pregnancies were reported in three of the patients' partners, without any other clinical intervention offered to the couple.. Switching from valproic acid to levetiracetam or lamotrigine improved sperm counts and other sperm parameters in subfertile male patients and increased the chance of spontaneously conceiving in subfertile couples.

The effects of the antiepileptic drugs sodium valproate (VPA) and levetiracetam (LEV) on reproductive endocrine function, sexual function, and spermatozoa were explored, together with their possible etiological mechanisms, in Chinese Han men with epilepsy. Following VPA treatment (n=32), luteinizing hormone and follicle-stimulating hormone levels were significantly lower than in controls (n=30). The bioactive testosterone/luteinizing hormone ratio and the prolactin level were significantly elevated in the VPA treatment group. There were no significant differences in these hormones between the LEV treatment (n=20) and control groups. The rates of sperm morphologic abnormality (head, body, and tail) were significantly higher in the VPA treatment group than the control group but did not differ significantly between the LEV treatment and control groups. The sperm motility rate was significantly lower in the VPA treatment group (grade A sperm motility rate <25%, grade A+B sperm motility rate <50%) than in controls, as well as in the LEV treatment group (grade A sperm motility rate <25%). Patients in the VPA and LEV treatment groups had lower scores on questions 1, 2 and 3 of a simplified International Index of Erectile Function Scale than controls, but no significant difference on questions 4 or 5. The total International Index of Erectile Function Scale scores were significantly lower in the VPA and LEV treatment groups. We conclude that treatment with VPA adversely affects reproductive endocrine function, sperm parameters and sexual function to varying degrees in Chinese men with epilepsy.
