ANATOMY OF FEMALE REPRODUCTIVE SYSTEM

Page 3: A review to Obst & gynae

Limmer et al., Emergency Care, 11th Edition© 2009 by Pearson Education, Inc., Upper Saddle River, NJ

Anatomy

Female reproductive system is divided

into:

External genitalia (vulva)Internal genitalia andAccessory reproductive organs

PHYSIOLOGY (MENSTRUATION CYCLE)

• Length of menstrual cycle is 28 day• 14th day – Ovulation day

PHASES :- • Menstrual phase :- shedding of endometrium with

discharge through vagina. Release of FSH and low level of LH, ovarian estrogen secretion begins

• Proliferative phase:- endometrium regenrates and thickens in preparation for implantation. Single dominant follicle develops to mature follicle, decrease in FSH level (negative feedback), increase in LH (positive feedback), Ovulation occurs

Page 5: A review to Obst & gynae

Limmer et al., Emergency Care, 11th Edition© 2009 by Pearson Education, Inc., Upper Saddle River, NJ

DOT Directory

• Leutal phase:- begins after ovulation and is a relatively finite time period of about 12 to 14 days under LH secretion , Corpus leuteum is formed from ruptured follicle, release of progestrone and estrogen

Progestrone helps preparation of endometrium

If fertilization does not Corpus leuteum becomes non functional after 10 to 12 days after ovulation and menstruation returns

EVENTS FOLLOWING FERTILIZATION

Process of fusion of spermatozoon with mature ovum which occurs in Ampulary part of fallopian tube

• MORULA: two cell stage 30 hrs after fertilization

• BLASTOCYST: It possesses an inner cell mass (ICM), or embryoblast, which subsequently forms the embryo, and an outer layer of cells, or trophoblast, surrounding the inner cell mass and a fluid-filled cavity known as the blastocoele 

Page 7: A review to Obst & gynae

Limmer et al., Emergency Care, 11th Edition© 2009 by Pearson Education, Inc., Upper Saddle River, NJ

DOT Directory

• Blastocyst formation begins at day 5 after fertilization 

• IMPLANTATION: occurs in endometrium between 10-11th day.

• TROPHOBLAST: placenta and fetal membrane develop from trophoblast

• DECIDUA: endometrium of the pregnant uterus

• CHORION: outermost layer of the two fetal membrane

• AMNION: inner layer of the fetal membrane

PLACENTA AND FETAL MEMBRANE

• Placenta is discoid in shape, with two surfaces

Maternal (rough and spongy) Foetal surface (covered by smooth and glistening

amnion with umbilical cord attached) Fetal blood flow through the placenta is 400 ml/mt Fetal membrane has two parts Amnion (inner

smooth layer) and Chorion (outer thick layer)

UMBILICAL CORD (Funis)

• Wharton’s jelly:- a gelatinous substance within the umbilical cord

• There are 2 umbilical arteries (deoxygenated blood) and one umbilical vein (oxygenated blood)

• Length: 50cm

Stages of Pregnancy

1st trimester (first 12 weeks)– Fetus is being formed

2nd trimester (13-28 weeks)– Uterus grows rapidly, reaching the

umbilicus

3rd trimester (29-40 weeks)– Uterus now reaches the epigastrium

DIABETES IN PREGNANCY

• Glucose travels across the placental membrane via facilitated diffusion

• Glucagon is present in the fetal circulation at 8 weeks of gestation

• FIRST TRIMESTER : Maternal fasting blood glucose level decreases slightly to approximately 75mg/ 100ml of blood because of the increased glucose supplied to the fetus

• SECOND TRIMESTER : Placental hormones (human placental lactogen,progesterone, estrogen) have a diabetogenic effect (producing diabetic-like state). HPL breaks down adipose tissue and release glycerol and fatty acid for the use of primary maternal fuel

Page 72: A review to Obst & gynae

Limmer et al., Emergency Care, 11th Edition© 2009 by Pearson Education, Inc., Upper Saddle River, NJ

DOT Directory

• Third trimester: Delivery of placenta brings about an abrupt drop in the levels of circulating placental hormones, insulinase, & cortisol

CRITERIA FOR DIAGNOSIS OF GESTATIONAL DIABETES MELLITUS

Criteria for diagnosis of GDM with 100gm of oral glucose

GTT: Venous plasma (mg/dl) TIME mg/dl Fasting 1 hour 2 hours 3 hours

POST PARTUM HAEMORRHAGE

• Bleeding in excess of 500 ml following delivery is called PPH

TYPES:-

• Primary PPH - occurs in the third stage of labour. It is defined as a loss of blood from the genital tract within the first 24 hours after birth.  

• Secondary PPH - occurs 24h-12 weeks after birth (end of puerperium).
