Birth Control Methods01:22

Birth Control Methods

7.2K
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 Systems01:21

Intrauterine Drug Delivery Systems

123
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...

Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

2.4K
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

5.1K
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

5.0K
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

210.4K
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...

Area of Science:

  • Reproductive Health
  • Contraception Research
  • Public Health Policy

Background:

  • Emergency contraception (EC) is crucial for preventing unintended pregnancies post-unprotected intercourse.
  • Over the last 15 years, US access to and utilization of EC have significantly increased.
  • Current research explores tailoring EC prescriptions based on factors like patient weight and concurrent contraceptive use.

Purpose of the Study:

  • To review the current landscape of emergency contraception access, use, and future directions.
  • To identify existing barriers to effective integration of EC into reproductive healthcare.
  • To highlight the availability of various EC methods and the ideal of cost-free access.

Main Methods:

  • Literature review of EC access, utilization, and prescribing trends.
  • Analysis of emerging data on personalized EC approaches.
  • Examination of policy and practical barriers affecting EC provision.

Main Results:

  • Increased availability and uptake of emergency contraception in the United States.
  • Identification of multiple EC methods: oral levonorgestrel, oral ulipristal acetate, and copper intrauterine devices.
  • Significant barriers persist, including knowledge gaps, cost, stocking issues, and legal exemptions for providers.

Conclusions:

  • While EC access has improved, challenges hinder its seamless integration into routine reproductive health services.
  • Personalized EC prescribing and ensuring low-cost access are key areas for future development.
  • Addressing provider and patient knowledge, cost, and regulatory hurdles is essential for optimizing EC's role.
