Birth Control Methods01:22

Birth Control Methods

7.4K
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Intrauterine Drug Delivery Systems

151
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

Hormonal Control of the Ovarian Cycle

7.8K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle.  At puberty, GnRH secretion increases in both frequency and...

Ovarian Cycle01:27

Ovarian Cycle

5.7K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

2.4K
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Oogenesis02:07

Oogenesis

71.6K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Summary
This summary is machine-generated.

Oral contraception (OC) prevents pregnancy and manages menstrual symptoms. OCs with levonorgestrel may offer a lower risk of venous thromboembolism (VTE) compared to other formulations.

Area of Science:

  • Reproductive Health
  • Endocrinology
  • Pharmacology

Background:

  • Oral contraception (OC) is a widely used method for pregnancy prevention.
  • OCs are also prescribed off-label for various gynecological conditions like acne, hirsutism, and menstrual irregularities.
  • Numerous OC formulations are available, including cost-effective generic options with similar efficacy.

Purpose of the Study:

  • To review the applications, contraindications, and safety profiles of oral contraceptives.
  • To highlight the importance of patient screening, particularly for contraindications like hypertension and VTE risk.
  • To compare the risks associated with different OC formulations, focusing on VTE.

Main Methods:

  • Review of existing literature on oral contraception.
  • Analysis of contraindications and necessary pre-prescription evaluations.
  • Comparison of progestin types and their association with venous thromboembolism risk.

Main Results:

  • Blood pressure measurement is the sole required physical examination before prescribing OCs.
  • Specific medical conditions such as hypertension, migraine, breast cancer, and VTE risk are contraindications.
  • Oral contraceptives containing second-generation levonorgestrel demonstrate a reduced risk of VTE compared to those with other progestins.

Conclusions:

  • Oral contraception is a versatile treatment for both pregnancy prevention and menstrual symptom management.
  • Careful patient selection is crucial, with blood pressure monitoring being a key screening step.
  • Levonorgestrel-containing OCs may be preferable due to their lower association with venous thromboembolism.
