assignment I’ll be discoursing on the significance of reproductive biology and
what this natural science is all about.
It is a
field of studies in which reproduction in humans, animals and plants are
examined; but I’ll be focusing on what concerns humans.
biology includes the study of a wide number of branches such as:
The set of organs inside an organism which work together to produce
offsprings is called the reproductive system. The sexes of differentiated
species have significant functional structures that allow a combination of
genetic material between two individuals and thus the possibility of greater genetic
fitness of the offspring
Endocrinology is the study of hormones, which are chemical molecules
directly released into the bloodstream whose effect is aimed at particular
cells in particular organs.
Secreted by endocrine glands, they tend to have long-lasting effects;
an example of an endocrine gland is the Pituitary
Gland, commonly known as the “master gland” due to the hormones produced
by it acting on other glands, directing them to release the necessary hormones.
Hormones have an impact and regulate a vast variety of body functions
such as development and growth, sugar regulation, adrenaline etc. and any abnormality/irregularity
in them will result in endocrinologists work to cure these threats to mankind
Sexual development (puberty)
The sexual maturity is the stage in which an organism becomes capable to
reproduce itself and generate offsprings, the period in the life cycle of a
living being in which physical growth has stopped or reached a certain stage of
It’s followed by the appearance of secondary sexual characteristics
which differentiate an immature individual with a mature one (e.g.) the larynx
becomes larger in male adult humans,
which results in a deeper voice; human children, on the other hand, have a more
It’s a process in which organism(s) generate other organism(s) , and it
occurs in two different ways:
Ø In the sexual reproduction the genetic information from 2 organisms (a
father and a mother) is combined to produce offsprings which are genetically
different to either parent but physically similar to both. The mother and the
father produce gametes (sex cells) by meiosis, which only have one copy of each
chromosomes, so that when gamete fusion takes place, the offspring will get the
right amount of chromosomes (two copies of each).
Ø In the asexual reproduction there’s
only one parent. No fusion of gametes, no mixing of chromosomes and no genetic
variation so the offsprings are genetically identical to that parent- they’re
clones. This process happens by mitosis, an ordinary creates a new cell by dividing in two
Is the natural capability to produce offspring, and it depends on
factors like nutrition, sexual behavior, culture, lifestyle etc.
Is controlled by hormones, meaning that knowledge of hormones can be used to
decide to increase, or reduce, the chances of fertilisation and pregnancy.
When there’s a lack of fertility (infertility) biologists
look for solutions to it
contraceptive, ‘the pill’, greatly reduces the chances of mature eggs being
produced. The pill contains oestrogen, or oestrogen and progesterone. These
hormones inhibit the production of FSH, which in turn stops eggs maturing in
understanding of reproductive
