Sexual attraction existed in different cultures is controversial. Pheromones have been determined to play a role in sexual attraction between people. They influence gonadal hormone secretion, for example, follicle maturation in the ovaries in females and testosterone and sperm production in males. Research conducted by Donald G.

A hormone-antioxidant combination may improve sperm count and motility. However, there is only some low quality evidence from few small studies that oral antioxidants given to males in couples undergoing in vitro fertilisation for male factor or unexplained subfertility result in higher live birth rate. It is unclear if there are any adverse effects. Administration of luteinizing hormone (LH) (or human chorionic gonadotropin) and follicle-stimulating hormone (FSH) is very effective in the treatment of male infertility due
