まとめ

授乳だけでは信頼性の高い避妊手段ではありません. 哺乳期アメノレアは,月経が戻った後の他の方法と組み合わせると,6ヶ月間,そして最大12ヶ月間,優れた保護を提供します.

科学分野:

生殖器保健は,生殖器の健康についてです.
母親と子供の健康について
避妊は避妊手段として使います.

背景:

哺乳は,世界中で広く実践されています.
哺乳期アメノレアは,月経のない自然な産後期である.
避妊方法としての乳児期アメノレアの有効性は議論されている.

研究の目的:

オーストラリアの女性における哺乳期アメノレアと無排卵の期間を記録する.
授乳中の女性の受胎確率を比較し,無防備の性交を行った.
避妊手段として乳児期アメノレア法 (LAM) の有効性を評価する.

主な方法:

栄養が充実したオーストラリアの女性で,母乳の授乳を継続した将来的研究.
哺乳期アメノレアと無排卵の記録期間.
異なる性交シナリオの下での概念の理論的累積確率を比較する.

主要な成果:

すべての女性は母乳授乳中に排卵を再開しました;母乳授乳だけでは効果的な避妊ではありません.
哺乳期アメノレアおよび月経後の他の方法でのみ無保護性交の場合:妊娠6ヶ月で1.7%,妊娠12ヶ月で7%,妊娠24ヶ月で13%.
哺乳期アメノレア法 (LAM) は,産後最初の6ヶ月間の優れた避妊保護を提供し,12ヶ月まで良好な保護を提供します.

結論:

ベラージョ・コンセンサスガイドラインは,避妊方法として,授乳期アメノレアに拡張することができます.
LAMは,授乳を継続する女性にとって,産後12ヶ月まで信頼性の高い避妊手段を提供しています.
出産後に月経が再開されると,代替的避妊法は不可欠です.

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Drugs for Treatment of Constipation-Predominant IBS

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

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...

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 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...
