Birth Control Methods

2.3K
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...

Hormonal Regulation of the Menstrual Cycle

678
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...

Hormonal Regulation

33.6K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hormonal Control of the Ovarian Cycle

2.6K
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...

Gonadal and Placental Hormones

1.7K
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...

Hormonal Regulation of Blood Pressure01:17

Hormonal Regulation of Blood Pressure

3.1K
Endocrinal or hormonal intervention in the cardiovascular system is predominantly exerted by the catecholamines - epinephrine and norepinephrine, as well as a slew of hormones that interact with renal function to modulate blood volume.
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction...

Area of Science:

  • Reproductive Health
  • Maternal-Infant Health
  • Contraception Research

Background:

  • Controversy exists regarding concurrent promotion of breastfeeding and immediate postpartum contraception.
  • Understanding women's experiences is crucial for informed decision-making.

Purpose of the Study:

  • To explore postpartum women's perspectives on breastfeeding behaviors.
  • To assess the impact of immediate postpartum contraceptive methods on breastfeeding over six months.

Main Methods:

  • Secondary analysis of a prospective cohort study (N=471) involving three contraceptive groups: long-acting reversible (n=200), depot medroxyprogesterone acetate (n=98), and non-hormonal (n=173).
  • Breastfeeding defined as any human milk provision.
  • Data collected at hospital discharge, 6 weeks, 3 months, and 6 months postpartum, focusing on breastfeeding rates, exclusivity, concerns, and discontinuation reasons.

Main Results:

  • No significant difference in any breastfeeding rates at 6 months postpartum across hormonal and non-hormonal contraceptive groups (20.1% vs. 21.7% vs. 13.9%, p > 0.05).
  • Discontinuation of breastfeeding due to decreased milk supply did not significantly differ between groups at any time point (p > 0.05).

Conclusions:

  • Immediate postpartum contraception choice did not influence breastfeeding perspectives or behaviors within the first six months.
  • Findings suggest that women can utilize various immediate postpartum contraceptive methods without negatively impacting their breastfeeding journey.
