Why are there so many different types of oral contraceptives? – The Estrogen Equation

Well, if you’ve read my previous post (which I’m sure you did!) you already know that the two main components of combined OCP’s are estrogen and progesterone.  What makes each type of pill distinct is the way in which these two components are dosed and formulated.  In this post, let’s discuss only the estrogen component.  We can talk about the progesterone later.

Combination OCP’s can be described as low-dose, medium-dose or (rarely) high-dose.  This refers to the dose of estrogen in the tablet.  A low-dose pill usually contains 20 micrograms of estrogen.  Medium dose pills contain between 30 and 35 micrograms.  Higher doses can go up to 50 micrograms.   

Why does it matter?  Well, a low-dose pill is great for somebody who needs the pill for pregnancy prevention, but doesn’t require the higher doses needed to suppress other conditions (like endometriosis or excessive menstrual bleeding).  A low dose of estrogen also minimizes the risk of complications from oral contraceptives (such as an increased risk of blood clots and other potentially life-threatening medical conditions). 

So, why wouldn’t everyone choose to take a low-dose pill?  Some women taking low-dose pills may not have bleeding during the week of placebos (inactive pills) because the low dose of estrogen keeps the lining of the uterus (womb) very thin.  Therefore, little tissue is shed (as menstrual flow) when the body withdraws from the estrogen.  Amenorrhea (absence of a period) can be normal and healthy in this situation and is not a cause for concern in the absence of other symptoms. 

In some women, bleeding between periods (metrorrhagia) may occur when the dose of estrogen is too low to stabilize the lining of the uterus between cycles.  If this occurs, it doesn’t mean the pill isn’t protecting you against pregnancy.  It just means you may need to switch to a different pill in order to reduce inconvenient or unpredictable bleeding

Spotting or mid-cycle bleeding can also be more likely to occur on a low-dose pill if doses are missed or are taken late.  Therefore a low-dose pill may be a poor option for women who can’t manage to take their pill on time every day.  Obviously, back-up contraception (a condom, perhaps?) should be used when necessary.

Oral contraceptives with 30 to 35 micrograms of estrogen may be a better choice for women who need to suppress their menstrual cycles because of endometriosis, pelvic pain, excessive menstrual bleeding (menorrhagia), or who have had irregular bleeding on lower dose oral contraceptives. 

If they dose of estrogen is the same in every pill, the type of pill can be called “monophasic.”  Some oral contraceptives have a dose of estrogen which varies from the first to the third week (triphasic).  These pills are meant to mimic the natural variation in hormones that occurs during a normal menstrual cycle.  Whether a monophasic or a triphasic pill is right for you will depend on a number of factors which you may wish to discuss with your gynecologist.

Demystifying Hysterectomy Part III: Risks and Benefits

Having a hysterectomy means that you will no longer have the ability to bear children.  It also means you should no longer experience menstrual bleeding (although you may experience other cyclic changes depending upon whether you still have ovaries).  Hysterectomy alone (ie without removal of or damage to the ovaries) does not result in menopause.  However, hormonal changes after hysterectomy are possible. 

Many women are concerned that removal of the uterus will adversely affect their sexual functioning and satisfaction.  There are no studies demonstrating that hysterectomy (with or without removal of the cervix) has a negative effect on patients’ sex lives.  Neither the uterus nor cervix itself contributes to vaginal lubrication or orgasmic response. Most patients’ male partners can not detect the presence or absence of a uterus or cervix and among those who can, few feel that it impacts their experience during intercourse.  Therefore, the best predictor of sexual satisfaction and functioning after hysterectomy is your sexual satisfaction and functioning prior to surgery.

You should discuss these concerns with your gynecologist before considering any kind of surgery to remove all or part of your uterus.

Complications from hysterectomy are uncommon but can be serious.  Although it is impossible to predict or list every possible problem, these infrequent complications may include infection, bleeding, thromboembolic events (blood clots), injury to adjacent organs, bladder or bowel dysfunction, nerve injury, postoperative pain, and anesthesia complications.  You should talk to your doctor about the possible complications of any treatment you consider undergoing.

Hysterectomy is permanent.  Even when performed via minimally invasive techniques, it is still a major surgery. 

Other options for managing certain gynecologic conditions may be appropriate.  These options may include expectant management (watchful waiting), therapy with hormonal or other types of medication, the use of interventional radiology (uterine artery embolization), targeted ultrasound ablation, or other fertility-sparing surgical procedures (myomectomy, ablation of endometrium or endometriosis).

The choice of whether hysterectomy is the right option for you depends on a number of factors.  Talk to your doctor about your condition and all of your options when considering hysterectomy as part of a treatment plan.

Demystifying Hysterectomy Part II: “How and why is hysterectomy performed?”

A hysterectomy can be performed in several ways. Minimally invasive surgical techniques include the removal of the uterus (and/or ovaries) through laparoscopy, a surgical technique which involves the insertion of long thin instruments through very small holes in the patient’s abdomen.  Hysterectomy can also be done via the vagina in a procedure called vaginal hysterectomy.  Despite the proven benefits of minimally invasive surgical techniques, the most common method of removing the uterus is still through an open abdominal incision called a laparotomy.  

Hysterectomy is used to treat a number of gynecologic conditions including uterine fibroids, adenomyosis, endometriosis, intractable pelvic pain, pelvic organ prolapse, and certain types of cancer.  It may also be required in certain types of emergencies (such as hemorrhage during childbirth) or electively (in persons undergoing gender reassignment).

Understanding Ovarian Cysts

Ovarian cysts are very common and can affect women of all ages.  Most women will have an ovarian cyst at some time in their reproductive lives.  Although they are less common after a woman stops menstruating, they are present in up to 14.8% of postmenopausal women.

But what is an ovarian cyst?  An ovarian cyst is any collection of fluid, surrounded by a very thin wall, within an ovary (one of a pair of organs in the pelvis responsible for producing female hormones and eggs).  Eggs normally mature within the ovaries in small, fluid filled spaces called follicles.  Any ovarian follicle larger than two centimeters can be called an ovarian cyst.  They vary greatly in size (as big as a cantaloupe or larger!) and in etiology.  Most ovarian cysts are benign (non-cancerous) in nature.  Several common types are

  1. functional (or simple) ovarian cysts, which are related to the menstrual cycle and often resolve on their own
  2. endometrioid cysts, which are due to endometriosis, are often called “chocolate” cysts or endometriomas
  3. dermoid cysts (or teratomas) which can have solid components like hair or teeth

 

Many ovarian cysts are asymptomatic and are discovered only incidentally at the time of an exam or ultrasound.  However, some ovarian cysts cause problems.  Rupture of an ovarian cyst can cause bleeding or pain.  An enlarged ovarian cyst can cause an ovary to twist on the stalk containing its blood supply, a condition called torsion.  Ovarian cysts may also interfere with fertility treatments and goals. 

Surgery may be required to remove large cysts or to make sure a cancer is not present.

If you think you have symptoms consistent with an ovarian cyst, it is important to be evaluated by a physician.  Ultrasound or other imaging as well as simple blood tests may be done to help determine whether treatment is necessary.
