In normal men, 50 mg/day clomifene for 8 months has been found to increase testosterone levels by around 870 ng/dL in younger men and by around 490 ng/dL in elderly men. Estradiol levels increased by 62 pg/mL in younger men and by 40 pg/mL in elderly men. These findings suggest that the progonadotropic effects of clomifene are stronger in younger men than in older men. In men with hypogonadism, clomifene has been found to increase testosterone levels by 293 to 362 ng/dL and estradiol levels by 5.5 to 13 pg/mL. In a large clinical study of men with low testosterone levels (<400 ng/dL), 25 mg/day clomifene increased testosterone levels from 309 ng/dL to 642 ng/dL after 3 months of therapy. No significant changes in HDL cholesterol, triglycerides, fasting glucose, or prolactin levels were observed, although total cholesterol levels decreased significantly. Other activities
Clomifene is an inhibitor of the conversion of desmosterol into cholesterol by the enzyme 24-dehydrocholesterol reductase. Concerns about possible induction of desmosterolosis and associated symptoms such as cataracts and ichthyosis with extended exposure precluded the use of clomifene in the treatment of breast cancer. Continuous use of clomifene has been found to increase desmosterol levels by 10% and continuous high doses of clomifene (200 mg/day) have been reported to produce visual disturbances. Pharmacokinetics
Clomifene produces N-desmethylclomifene, clomifenoxide (clomifene N-oxide), 4-hydroxyclomifene, and 4-hydroxy-N-desmethylclomifene as metabolites. Clomifene is a prodrug most importantly of 4-hydroxyclomifene and 4-hydroxy-N-desmethylclomifene, which are the most active of its metabolites.
Although skin ulcers do not seem of great concern at a first glance, they are worrying conditions especially in people with diabetes, as they are at risk of developing diabetic neuropathy. Ulcers may also appear on the cheeks, soft palate, the tongue, and on the inside of the lower lip. These ulcers usually last from 7 to 14 days and can be painful. Discharges
Different types of discharges from ulcer are:
Serous, usually seen in healing ulcer
Purulent, seen in infected ulcer. Yellow creamy discharge is observed in staphylococcal infection; bloody opalescent discharge in streptococcal infection, while greenish discharge is seen in the case of Pseudomonas infection
Bloody (sanguineous), usually seen in malignant ulcers and in healing ulcers with healthy granulation tissue
Seropurulent
Serosanguinous
Serous with sulphur granules, seen in actinomycosis
Yellowish, as seen in tuberculous ulcer

Causes
The wounds from which ulcers arise can be caused by a wide variety of factors, but the main cause is impaired blood circulation. Especially, chronic wounds and ulcers are caused by poor circulation, either through cardiovascular issues or external pressure from a bed or a wheelchair. A very common and dangerous type of skin ulcer is caused by what are called pressure-sensitive sores, more commonly called bed sores, which are frequent in people who are bedridden or who use wheelchairs for long periods.Other causes producing skin ulcers include bacterial and viral infections, fungal infections and cancers. Blood disorders and chronic wounds can result in skin ulcers as well. Venous leg ulcers due to impaired circulation or a blood flow disorder are more common in the elderly.
