A thorough gynecologic examination should include an
evaluation of hair distribution, clitoris size, Bartholin
glands, labia majora and minora, and any condylomata
acuminatum or other lesions that could indicate the
existence of venereal disease.
Bimanual examination should be performed to establish
the direction of the cervix and the size and position of the
uterus to exclude the presence of uterine fibroids, adnexal
masses, tenderness, or pelvic nodules indicative of infection
The examination of the extremities is important to rule out
malformation, such as shortness of the fourth finger or
cubitus valgus, which can be associated with chromosomal
abnormalities and other congenital defects. Examine the
skin to establish the presence of acne, hypertrichosis, and
Postcoital test (PCT), Sims-Huhner test
Saline infusion sonography
Progesterone greater than 4 ng/mL
Sonographic confirmation of follicle rupture with
serial ultrasonography can also be performed.
Basal body temperature charts prefer to use
urinary ovulation predictor kits as they are more
accurate and easier to administer
Late menstrual endometrium
The uterine lining changes throughout the normal menstrual cycle
Volume - 2-5 mL
pH level - 7.2-7.8
Sperm concentration - 20 million or greater
Motility - 50%, forward progression
Morphology - Normal sperm (>4%)
White blood cells - Fewer than 1 million cells/µL

Collection condoms are sterile and made
from silicone or polyurethane, as latex is
somewhat harmful to sperm. Semen can also
be collected by masturbation into a sterile
container, such as a specimen cup.
In vitro fertilisation (IVF)
1. Retrieval of pre-ovulatory oocytes from the woman.
2. In vitro fertilization by sperm.
3. Culture to 8 or 16 cell stage.
4. Transfer to the uterus.
1. Ovarian follicles stimulated
2. Mature oocytes aspirated at laproscopy
3. Oocytes placed in a petri dish to culture with
4. Cleavage monitored in fertilized egg till 6-8 cell
5. Embryo transferred into vagina and cervical canal
•In vivo fertilization occur within 12 hours
•In vitro fertilization is not possible after
•Most human sperms do not survive for
more than 48 hours in the female genital

Prior to any GIFT, IVF, or ICSI procedure, the woman
receives hormones to stimulate development of the
The fluid containing the ova is placed in a laboratory
dish and observed under a microscope.
The ovum is located and its stage of maturity noted.
It is then carefully cultured in a special nutrient.
Approximately three hours before the procedure, a semen sample from the
husband is obtained.
The sperm is washed and prepared for loading into the same catheter into which
several of the wife's ova will be placed.
The ova are obtained by transvaginal needle aspiration (no surgical incision) via
an ultrasound guide.
Sperm and ova are sequentially loaded into the catheter, which is then introduced
into the patient's fallopian tube through a tiny incision in her abdomen.
