Birth Control Methods01:22

Birth Control Methods

5.8K
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...

Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

1.4K
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Ovarian Cycle01:27

Ovarian Cycle

3.2K
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...

Infertility in Females01:28

Infertility in Females

3.6K
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of...

Meiosis II01:57

Meiosis II

206.1K
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each...

Hormonal Control of the Ovarian Cycle01:30

Hormonal Control of the Ovarian Cycle

6.3K
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...

Summary

Teen pregnancy remains high in the US despite declines. Emergency contraception (EC) offers a safe and effective way to prevent pregnancy after unprotected sex, reducing overall teen birth rates.

Area of Science:

  • Public Health
  • Adolescent Medicine
  • Reproductive Health

Background:

  • The United States has higher teen birth rates compared to other high-income nations, despite a 2-decade decline.
  • Emergency contraception (EC) is a crucial tool for preventing pregnancy following unprotected or underprotected intercourse.

Purpose of the Study:

  • To update pediatricians and physicians on available emergency contraceptive methods.
  • To present current data on the safety, efficacy, and usage of EC in adolescents.
  • To advocate for routine counseling and advance prescription of EC as a public health strategy.

Main Methods:

  • Review of current emergency contraceptive methods, including FDA-approved oral medications (ulipristal, levonorgestrel), off-label combined oral contraceptives, and copper intrauterine devices.

  • Analysis of indications for EC use, encompassing contraceptive failure, condom issues, missed doses, vomiting, and sexual assault.
  • Policy statement development based on updated scientific evidence and clinical recommendations.
  • Main Results:

    • Emergency contraception is safe and effective when used within 120 hours of unprotected intercourse.
    • Various methods are available, catering to different needs and circumstances.
    • Adolescents can benefit significantly from timely access to and information about EC.

    Conclusions:

    • Educating healthcare providers on EC is essential for effective implementation.
