Recombinat hormones: Molecular biology and biochemistry of human recombinant follicle stimulating hormone (Puregon®)

The follicle-stimulating hormone receptor: biochemistry, molecular biology, physiology, and pathophysiology.

Bioequivalence of subcutaneous injections of recombinant human follicle stimulating hormone (Puregon(R)) by Pen-injector and syringe.

A randomized, single-centre, cross-over study was designed to compare the bioavailability of two pharmaceutical formulations of recombinant human follicle stimulating hormone (recFSH; Puregon(R)): (i) a dissolved cake injected by a normal syringe; and (ii) a ready-for-use solution injected using a device referred to as Puregon(R)Pen. Twenty-two healthy female volunteers underwent one of two adm...

Recombinant follicle stimulating hormone (rFSH; Puregon) in assisted reproduction: more oocytes, more pregnancies. Results from five comparative studies.

The clinical assessment of recombinant follicle stimulating hormone (rFSH; Puregon) in assisted reproduction technologies such as in-vitro fertilization (IVF) has probably been the most extensive clinical trial programme ever performed for the evaluation of a new fertility drug. It started with a pilot study to evaluate the potential of rFSH to stimulate the ovaries in the absence of luteinizin...

Follicle-stimulating hormone and human spermatogenesis.

The role of follicle-stimulating hormone (FSH) in the control of spermatogenesis is not well established in any species, including man. We studied the effect of an experimentally-induced, selective FSH deficiency on sperm production in normal men. After a 3-mo control period, five normal men received testosterone enanthate (T) 200 mg i. m. weekly to suppress luteinizing hormone (LH) and FSH, un...

Overnight radioimmunoassay of human follicle-stimulating hormone.

A radioimmunoassay procedure for follicle-stimulating hormone in serum has been developed in which the assay mixture is incubated at 37#{176}C for a total of 22 h, rather than at 4#{176}C for 4-7 days. The withinassay coefficients of variation for the 37#{176}C and 4#{176}C methods, respectively, are 7.7% and 5.0%, while the between-assay variations are 13.8% and 9.9%. Comparison of values for ...
