Urinary tract infections (UTIs) are rare in adult males younger than 50 years but increase in incidence thereafter. Causes of adult male UTIs include prostatitis, epididymitis, orchitis, pyelonephritis, cystitis, urethritis, and urinary catheters.
Definition: Gametes are reproductive cells (sex cells) that unite during sexual reproduction to form a new cell called a zygote. Male gametes are sperm and female gametes are ova (eggs). In seed bearing plants, p ollen is the male sperm producing gametophyte. Female gametes are contained within the plant ovary.
A gamete is a reproductive cell such as a sperm or egg cell. When the sperm and egg come together and fertilize, a zygote is formed.Sperm move; eggs do not. The gametes, sperm and egg each contain one set (haploid) of the total number of chromosomes necessary for fertilization and that allows the zygote to grow to maturity.The zygote contains all the chromosomes necessary. It is diploid --having both sets of chromosomes.perm move; eggs do not.
