Urofollitropin is a purified form of follicle-stimulating hormone (FSH) that is manufactured by extraction from human urine and then purified to remove various proteins and other substances. FSH is important in the development of follicles (eggs) produced by the ovaries. Given by subcutaneous injection, it is used in combination with human chorionic gonadotropin (hCG) to assist in ovulation and fertility. It is also used with in vitro fertilization methods. The dosage is adjusted to each individuals response.The most common side effects are abdominal or pelvic pain, bloating, as well as redness, pain or swelling at the injection site. Follitropin is possibly associated with increased risk of endometrial carcinoma. It is not for use during pregnancy, as there is evidence for birth defects under follitropin treatment.Bravelle sold in the United States from March 2014 through October 2015 is subject to a recall and refund by its maker, Ferring Pharmaceuticals, because certain batches of the medicine had a lower strength than stated.

Lymphocytosis is an increase in the number or proportion of lymphocytes in the blood. Absolute lymphocytosis is the condition where there is an increase in the lymphocyte count beyond the normal range while relative lymphocytosis refers to the condition where the proportion of lymphocytes relative to white blood cell count is above the normal range. In adults, absolute lymphocytosis is present when the lymphocyte count is greater than 5000 per microliter (5.0 x 109/L), in older children greater than 7000 per microliter and in infants greater than 9000 per microliter. Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds 40%, it is recognized as relative lymphocytosis. Causes
Lymphocytosis is a feature of infection, particularly in children. In the elderly, lymphoproliferative disorders, including chronic lymphocytic leukemia and lymphomas, often present with lymphadenopathy and a lymphocytosis.Causes of absolute lymphocytosis include:

acute viral infections, such as infectious mononucleosis (glandular fever), hepatitis and Cytomegalovirus infection
other acute infections such as pertussis
some protozoal infections, such as toxoplasmosis and American trypanosomiasis (Chagas disease)
chronic intracellular bacterial infections such as tuberculosis or brucellosis
chronic lymphocytic leukemia
acute lymphoblastic leukemia
lymphoma
post-splenectomy state
CARD11-related congenital B cell lymphocytosis (rare, also known as BENTA disease)Causes of relative lymphocytosis include:

age less than 2 years;
acute viral infections;
connective tissue diseases,
thyrotoxicosis,
Addisons disease,
splenomegaly with splenic sequestration of granulocytes. Diagnosis
Lymphocytosis is usually detected when a complete blood count is obtained. If not provided the lymphocyte count can be calculated by multiplying the total white blood cell (WBC) count by the percentage of lymphocytes found in the differential count.
