A significant decrease in human fertility has been observed in the last 50 years. Approximately 15% of couples of reproductive age have fertility problems and about half of these cases are because of male factors. A growing body of evidence suggests that environmental factors play an important role in the causes of male infertility.

Besides producing gametes, the gonads also produce sex hormones. Structures of the.

Adults are hermaphrodites, meaning they have both male and female reproductive structures. Monogeneans have a series of hooks which are used to attach onto fish, and as a result, could lead to infections.

The most notable change between this edition and the last is the inclusion of. Big Picture. The female reproductive system consists of the ovaries, uterine tubes, uterus, vagina, and external genitalia. These organs remain underdeveloped for about the first 10 years of life.

During adolescence, sexual development occurs and menses first occur (menarche). Cyclic changes occur throughout the reproductive period. Monogeneans possess a relatively simple, single life cycle compared to other parasitic worms.

It is direct (they have no intermediate hosts), and although they are true hermaphrodites, the male reproductive system becomes functional before the female part. The eggs hatch, releasing a heavily ciliated (fringed) larval stage known as an oncomiracidium. In the Monogenea the principal contributions to phylogeny and evolutionary considerations of spermatological characters were made by Justine (b) and Justine et al.

In these studies, the monopisthocotylean and polyopisthocotylean monogeneans were each defined on the basis of synapomorphies for the spermatozoon. Reproductive Health Epidemiology Series Case Study: Reproductive Tract Infections—Ethiopia T.

Kearn, I. WhittingtonCited by: Human reproductive system, organ system by which humans reproduce and bear live offspring. Provided all organs are present, normally constructed, and functioning properly, the essential features of human reproduction are (1) liberation of an ovum, or egg, at a specific time in the reproductive cycle, (2) internal fertilization of the ovum by spermatozoa, or sperm cells, (3) transport of the.

At fertilization, the chromosomes in one male gamete, called a sperm (or spermatozoon), combine with the chromosomes in one female gamete, called an oocyte. The function of the male reproductive system (Figure 1) is to produce sperm and transfer them to the female reproductive tract.
