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...
Hormonal Control of the Ovarian Cycle01:30

Hormonal Control of the Ovarian Cycle

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...
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.
Ovarian Cycle01:27

Ovarian Cycle

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 length...
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...
The Menstrual Cycle01:19

The Menstrual Cycle

The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a uterine...

Area of Science:

  • Reproductive Health
  • Family Planning
  • Maternal Health

Background:

  • The Lactational Amenorrhoea Method (LAM) is a natural family planning method for postpartum women.
  • LAM is effective for up to six months if exclusive breastfeeding, amenorrhoea, and no infant supplementation are maintained.
  • Barriers to LAM understanding and consistent use exist among women and healthcare providers.

Purpose of the Study:

  • To explain the mechanism and practical support strategies for LAM.
  • To present a local initiative for improving LAM uptake and adherence.
  • To address challenges in LAM's understanding and application.

Main Methods:

  • Literature review on LAM's efficacy and support mechanisms.
  • Development of an informational leaflet based on national guidelines and user input.
  • Implementation of brief training for healthcare professionals on LAM counseling.

Main Results:

  • The study outlines the physiological basis of LAM.
  • An information leaflet and training program were created to enhance LAM knowledge.
  • The initiative aimed to ensure consistent and accurate information delivery by health professionals.

Conclusions:

  • Effective LAM use relies on exclusive breastfeeding and sustained amenorrhoea.
  • Information provision and targeted training are crucial for overcoming LAM adoption barriers.
  • Supporting LAM can improve contraceptive choices for breastfeeding mothers.
