Blocked fallopian tube/thick cervical mucus means sperm can't reach the egg.
No ovulation/hormone imbalance means there are no eggs produced.
Insufficent sperm or poor quality sperm means eggs won't fertilise
Gynaecologists have specialist knowledge of the functions and diseases of the femal reproductive system and treat problems like infertility.
They have a numer of ways to assist conception:
- IVF: You have hormone treatment to stimulate ovulation. Eggs are then surgeically revmoved and penetrated by sperm in a test tube. At 8 cell division, they are placed into the uterus or fallopian tube.
- Egg Donation: The involves eggs being collected from donars then followed by the IVF procedure.
- Doner Insemination: Donated sperm are placced directly into the uterus or used in an IVF procedure.
- Partners sperm can be placed directly in to uterus.
- ICSI (Intra-cytoplamic sperm injection): An individual sperm is injected directly in to the egg/
- Surrogacy: Another women has a child for those who can't have a child.

Length of Pregnancy
Pregnacy is divided in to 3 trimesters: 1 to 3 months, 4 to 6 months and 7 to 9 months.
Weeks 6 to 12
At week 6
- Initial development of legs, brain, spine, internal organs, blood, bines, muscles, ears and eyes.
- The embroyos heart uis beating.
At week 8...
- The foetus is more human
- The arms, legs, ears and eyes can be seen
- The foetus moves in the amniotic sac.
- Heart beat is visible on scan
At week 12, the foetus..
- fully formed with eyes closed
- swims by kicking
- can swallow, cleanth a fist, hiccup and **** its thub
- Has well developed sex organs
- Sensitive to heat, light and sound
Weeks 24 to 36
At week 24, foetus is..
- Weighs approximately 700g
- Has hair, wrinkled skin, fingernails and fingerprints
- Is covered in vernix and lanugo
- Is active, with definate periods of sleeping and waking
After 24 weeks,the baby grows and gets strongrer. If it was born now it would be viable because its development, expect the lungs is complete. If it was born now, it would need special care in NICU or SCBU.
By 32 to 36 weeks, the babys head is usually lying head downwards. This is the cephalic position.
The placenta, umbilical cord and amniotic sac are produced by the fertilised egg.
- is the only disposable organ in the body.
- Attached to the wall of the uterus and expelled after birth as the afterbith.
- Grows 2.5cm thick, 15cm across aqnd weighs 500g.
The placenta maintains and nourishes the baby by letting O2, amino fats, vitamins and minerals pass from the mothers blood. CO2 and waste prodcuts from the baby pass through the placenta to the mother and their blood doesn't mix.
Alcohol, nicotine, viruses, drugs and antibodies pass from the mother to baby through the placenta.
Amniotic Sac and Umbilical Cord
The amnotic sac is filled with animotic fluid which keeps the babys temperature at 37 degrees. Also cushions and protects baby from bangs.
The umbilical cord...
- Is approximately 50cm long and 2cm wide.
- Contains 3 blood vessels, carring blood between mother and baby.
- Is cut and clamped after birth.

Blood tests taken for...
- Hepatitis B
