Risks of contracting HIV
- Black
- IVDU
- MSM (anoreceptive especially)
- Vaginal delivery (25%)
In pregnancy with HIV mothers should
- Opt for C-section if high viral load
- Never breastfeed
- Mothers should take HAART indefinitely
- Infants should take PEP for 4 weeks
Acute HIV infection
13 weeks
Viral replication for HIV
6-12 hrs
HIV reduces
CD4+ T cells
through CCRJ surface receptor, this makes the individual more susceptible to infection
Normal CD4+ count is
>500
Anything < 200 = infectinon risk
Treatment for HIV
HAART (Highly Active Antiretroviral Therapy)
- Tenofovir: nucleoside reverse transcriptase inhibitors(NRTI)

Side effects of tenofovir
Nephrotoxic
Side effects of Efavirenz
- Sleep disturbance
- Mood disorders
Post Exposure Prophylaxis should be taken
within 72hrs for 28 days
Cancers that AIDS (acquired immune deficiency syndrome) increases risk of
- NHL (EBV)
- Cervical Cancer (HPV)
- Kaposi’s Sarcoma (HHV8 herpes)
Infections AIDS increased risk of
- Progressive Multifocal Lymphadenopathy (PML)
- Pneumocystis Pneumonia
- Cerebral toxoplasmosis- when <150 CD4+ toxoplasma gondi
- Cytomegalovirus- when < 50 CD4+
- TB
PML is caused by
John Cunningham virus
Pneumocystis Pneumonia is caused by
Pneumocystis jiroveci
Treatment for Pneumocystis pneumonia
Cotrimoxazole
Cerebral toxoplasmosis is caused by
toxoplasma gondi
Treatment for Toxoplasmosis
Pyrimethamine and Sulfadiazine
or cotrimoxazole
TB is caused by
Mycobacterium Tuberculosis
Menstruation lasts
28 days
<21 days = Polymenorrhea
>35 days = Oliomenorrhea
Normal volume of blood per period (cycle)
80ml
Any more than this (and for an extended period of time) is considered menorrhagia
Peak bleeding occurs
1-2 Days in
No periods in > 6 months is
amenorrhoea
Menometrorrhagia
Spotting between periods
Menstrual cycle is split into two phases divided by ovulation
- Follicular phase (starts at day 1)
- Menstrual stage
- Proliferative stage
- Ovulation (day 14)
- Luteal phase (ends at day 28)
- Secretory phase
Oestrogen is responsible for
Follicular phase
Progesterone is responsible for
Luteal phase
At ovulation, there is a
LH spike
Progesterone is secreted by
the corpus luteum
Progesterone peaks
7 days after ovulation
7 days before day 28
Fertility testing tests
Progesterone 7 days before end of period
Hypothalamus produces
GnRH
GnRH then stimulates
Anterior pituitary to produce LH and FSH
LH stimulates
Theca cells to produce androgens
FSH stimulates
granulosa cells to convert androgens to oestrogen
(by aromatase)
Oestrogen then goes on to
proliferate endometrial growth
A women is most fertile on
days 12, 13, 14
In males LH stimulates
Leydig cells to produce testosterone
In males FSH stimulates
sertoli cells to enhace spermatogenesis
Anti-mullerian hormone is used to measure
Ovarian reserve (levels of oocytes)
B-hCG (Human chorionic gonadotrophin)
- Secreted by syncytiotrophoblasts (early placenta structure)
- Is used as a pregnancy test
- Can also be very high in molar pregnancies, and ectopic pregnancies
Oestrogen increases
Breast development
Progesterone increases
breast tissue growth
Prolactin increases
mammary gland growth in breasts
Prolactin is inhibited by
dopamine

Due to testosterone and Mullerian inhibiting factor in males
Wolffian ducts will become the reproductive tract
Mullerian ducts will degenerate
“Wolffian = male alpha like wolf”
In females
Mullerian tracts will become the reproductive tract
Wolffian ducts will degenerate
a condition in which one or both of the testes fail to descend from the abdomen into the scrotum
