Sildenafil 110 mg troche

Harden et al 15 reported that a marked increase in testosterone levels was observed after 1 month of LEV treatment in 8 male adult patients with epilepsy.

However, Spencer showed that in 26 adult male patients with epilepsy, no statistically significant changes were found in sex hormone levels measured before taking LEV and after taking it for 13.7 weeks.

16 Herzog et al 17, 18 and Gil?Nagel et al 18 observed no change in sex hormone levels in men with epilepsy after LTG administration.

In our study, monotherapy of OXC, LEV, or LTG alone did not cause obvious changes of sex hormones in male adult patients with epilepsy. We speculated that conventional doses of OXC, LEV, or LTG alone or their metabolites do not mainly affect the cytochrome P450 enzyme system.

Semen quality decline is also one of the important factors that causes impaired fertility disorders of male patients with epilepsy. In the maturation of sperm, sex hormone regulation plays a very important role; LH stimulates testicular stromal cells to synthesize testosterone, and FSH acts on supporting cells in the seminiferous tubules, leading to synthesis of androgen?binding globulin (ABP).

Then, ABP and testosterone are combined and carried in spermatogonia and spermatocytes, so that germ cells obtain stable, high concentrations of androgen, and effectively differentiate into mature sperm.

Many studies have shown that epilepsy and a variety of AEDs can adversely affect the quality of semen, particularly older AEDs, most of which can affect the sex hormones and in turn have an impact on the occurrence and maturation of sperm.

19, 20 The epileptic abnormal discharge of brain neurons can also affect the function of the hypothalamic?pituitary?gonadal axis, indirectly affecting the quality of sperm. The effect of the AEDs on semen quality has only been reported by a few authors. Calabro et al 21 reported the case of a male patient with epilepsy who was diagnosed as infertile and had a marked reduction in semen quality. After 3 months of LTG treatment, the sperm count increased 2.7?fold and sperm motility increased 68%, and a pregnancy resulted after 5 months.

Cansu et al 22 found in an animal study that OXC can reduce the number of sildenafil 110 mg troche spermatocytes at all developmental stages, although the difference was not statistically significant. Kose?Ozlece et al 23 observed a significant decrease in sperm count and viability as the dose of VPA was increased, but the semen quality was restored after the VPA dose was tempered by combination with LTG. Baysal et al 24 found that when male rats received oral LEV for 70 days, histological examination of the rat's genital histopathology and semen analysis showed that at 300 mg/kg/d LEV, the male rats had obvious testicular damage, and the effect of LEV on rat semen quality was shown to be dose?dependent. In our study, the semen quality of the patients with epilepsy was significantly decreased compared with the healthy control group, suggesting that the reduction of semen quality may be mainly because of the seizures themselves.

There was a trend toward improvement in all sperm parameters before and after treatment with the 3 different novel AEDs compared with those before treatment, but there was only a statistically significant difference in the OXC treatment group.

In the LEV and LTG treatment groups, although comparison between before and after treatment showed a substantial improvement, no significant difference was observed.

We believe that these 3 AEDs have no significant negative effects on male semen quality at therapeutic doses and may improve the semen quality to some extent; treatment with OXC can improve the survival rate and FFMR of the sperm. It has been reported that men with epilepsy experience sexual dysfunction, including loss of libido, erectile dysfunction, and orgasm disorders. 25 In addition, some studies have reported that in male patients with epilepsy, the degree of sexual dysfunction is negatively correlated with anxiety and depression, not correlated with the frequency of seizures, but closely correlated with the location of epileptic seizures.

This includes temporal lobe epilepsy, in which sexual dysfunction

occurs

26 The possible mechanism is the temporal lobe area, especially the amygdala, which has a direct anatomical relationship with the hypothalamus and can act through repeated epileptiform discharges, leading to sexual dysfunction.

26 There have also been studies reporting that when measuring the genital blood flow in patients with epilepsy, patients with temporal lobe epilepsy had less blood flow to the genitals; this may, to some extent, explain the sexual dysfunction.

27 Newer AEDs (OXC, LEV, or LTG) might affect sexual function less than older AEDs.

4, 5, 28 They can cause sexual dysfunction by affecting the secretion of sex hormones 11 or by increasing the inhibition of GABA, inhibiting nerve conduction and reducing the transmission of sexual stimuli.

29 The effect of these AEDs on sexual function has been less reported, with contrasting results.

Different studies have pointed out that OXC can both improve sexual function in patients with epilepsy and can also cause sexual dysfunction. Luef et al 6 reported that among 228 adult male epilepsy patients with partial seizures and sexual dysfunction, 181 (79.4%) of them improved their sexual function after being treated with OXC monotherapy or by replacing other AEDs with OXC monotherapy for 12 weeks of treatment; moreover, 23 (10.1%) patients did not get worse, and the improvement in sexual function was more obvious in patients who had previously used enzyme?inducing AEDs. Calabro et al 7 reported that treatment with OXC at 1800 mg/d caused retrograde ejaculation in a 35?year?old man with traumatic epilepsy, and the retrograde ejaculation disappeared after switching to other AEDs.

However, Calabro et sildenafil 110 mg troche al 30 also reported that 2 young men with epilepsy had loss of libido and a lack of sex appeal after taking LEV, and recovered sexual function after switching to other AEDs.

In case studies or sample studies, LTG has not been found to have any adverse effects on sexual function, and it has been shown to have a positive effect on sexual function. 18, 31 A clinical study by Gil?Nagel et al 18 followed 141 patients with epilepsy treated with LTG as initial or replacement therapy for 4?8 months; male patients with epilepsy showed significant improvement in their sexual function compared with function before treatment. The authors thought that this was probably a multivariate result of an improvement in seizures, the elimination of adverse effects of other AEDs, and the stabilizing effect of LTG. In this study, the patients with epilepsy had a lower erectile function score than the healthy control group. In patients with epilepsy, premature ejaculation levels have a lower trend, but it was not statistically significant. These results, to some extent, suggest that epilepsy itself can adversely affect the erectile function score. The scores of erectile function and rx coupons sildenafil premature ejaculation sildenafil 110 mg troche were increased in the OXC, LEV, and LTG groups when compared between before and after treatment, but no statistical sildenafil 110 mg troche significance was found. This may be related to the small case number in this study. We also presume that these 3 AEDs may have effects on improvement of erectile function.

In conclusion, this study suggests that seizures may lead to a decrease in semen quality and lower marriage and fertility rates in male adult patients with epilepsy compared to healthy controls, but have no significant effect on erectile function, premature ejaculation, or sex hormones.

Treatment with OXC improved the FFMR and survival rate of sperm; treatment with LEV and LTG showed a notable improvement on semen quality, but this did not reach statistical significance.

Therefore, using these AEDs to treat adult male patients with epilepsy may be a more appropriate choice.
