Understanding Female Reproductory System & Pregnancy

I will not be going into the argument whether Ovaries are born with all the eggs or they keep producing new eggs! Female Reproductory System consists of Uterus, Fallopian Tubes & Vagina.

Few Basics on Female Reproductive System Organs:

  1. Vagina could be understood to be simply a Muscular Tube leading all the way to Uterus,
  2. The upper part of Uterus, above the entry point of fallopian tubes, called Fundus, is mostly Muscular,
  3. The lower part is Fibrous (Cervix) & extends into vagina,
  4. Thus, Uterus is partially supported by ligaments which comprise of Lymphatics (Lymph Nodes), Nerves, Blood Vessels, Connective Tissues & Muscular Fibres,
  5. Intravaginal Portion of Cervix (Portio Vaginalis) is laced with Mucous-Secreting Glands,
  6. Uterus is supplied blood from uterine arteries, branches go to Cervix & Vagina,
  7. Fallopian Tubes (Uterine Tubes) carry egg from Ovary to Uterus,
  8. Egg fertilisation generally takes place at Ampulla (Dilated Portion of fallopian Tube-Curves over ovary),
  9. Amniotic Sac is simply a Fluid Filled (Amniotic Fluid) Bag inside the mother’s womb (Uterus) & has a whole lot of role to play in Growth & Development of The Foetus,
  10. Carry on till the end of the post to know the whole

    procedure in very brief.

Pregnancy results from fertilisation of Ovum (Oocyte) & a Sperm (Spermatozoa). The Gestation Period (Pregnancy Cycle) usually lasts 40 Weeks. Healthy weight gain at the end of Gestation Period would be around 13-14 Kgs. Sperms are produced in Testicles, combines with Other Fluids-bio-Chemicals to form Semen & millions of sperms thus enter through the vagina towards Uterus.

Once a month, an ovum (or egg) matures in one of the Ovaries and via Fallopian Tube, travels to Uterus (A Process called Ovulation) (This happens through the menstrual cycle). Within 1-5 days of Ovulation as Fertilisation (i.e. if it takes place!) takes place, a Spermatozoa (Just one of them) unites with Ovum to form a Zygote (in the fallopian tube). The Zygote thereafter gets implanted to the walls of Uterus. Zygote contains half of DNA of each parent & subsequent development of Zygote forms Embryo (Mitosis Cell Division) and Placenta too is formed, which is a connecting organ between Foetus & Uterine Walls (Responsible for Nutrient Uptake (Including Blood) by the Foetus. The fertilisation may happen immediate or within few days (1-5) of ‘The course’ (The Living life of a sperm cell and an egg).  This is the commencement of pregnancy and specific hormones produced during pregnancy prevents uterus lining from shredding and therefore pregnant ladies do not have cycles.

Stepwise development of foetus (Development of Blood Circulatory System, Facial Features, CNS-Spinal Cord, Heart Beat, Body Limbs, Hair Growth, Response to Sound…..) finally resulting in a birth of a Healthy Baby. If all goes well, foetus would naturally align itself for a normal delivery – Head pressing onto the Cervix.
