Birth Control Methods01:22

Birth Control Methods

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 vasectomy...
Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

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...

Methods Of Healthcare Delivery System

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

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 release.
Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...

Summary

Family planning significantly reduces maternal deaths by lowering birth rates and preventing high-risk births. Increased contraceptive use between 1990-2005 averted over a million maternal deaths globally.

Area of Science:

  • Public Health
  • Demography
  • Reproductive Health

Background:

  • Family planning is known to reduce maternal mortality by decreasing birth frequency.
  • This study investigates family planning's dual role: reducing births and lowering the risk per birth.

Purpose of the Study:

  • To quantify the impact of rising family planning use on maternal mortality reduction from 1990-2005.
  • To assess how preventing high-risk, high-parity births affects the maternal mortality ratio (MMR).

Main Methods:

  • Utilized UN estimates for MMR and total fertility rate (TFR) to calculate averted births and deaths.
  • Analyzed data from 146 Demographic and Health Surveys on contraceptive use and birth risk factors.
  • Examined country-specific data on MMR by parity and age to understand impacts on high-risk births.

Main Results:

  • Over 1 million maternal deaths were averted between 1990-2005 due to declining TFR in developing nations.
  • Family planning indirectly reduced MMR by preventing high-parity and other high-risk births.
  • The indirect effect of family planning use can lower MMR by an estimated 450 points.

Conclusions:

  • Increased modern contraceptive use is crucial for reducing maternal mortality in developing countries.
  • Family planning offers a significant dual benefit in lowering maternal mortality rates.
  • Continued expansion of family planning services can further decrease preventable maternal deaths.
