By targeting specific biological processes such as ovulation, sperm transport, or hormone production various contraceptive methods intervene in the natural sexual reproductive cycle to control fertility. #FamilyPlanning #HumanReproduction #SexualReproductiveHealthRights

Previously, Prof Kimberley Brownlee from The University of British Columbia @UBCPhilosophy delivered a C&C webinar titled “𝐻𝑜𝑤 𝐷𝑜 𝑊𝑒 𝑀𝑖𝑡𝑖𝑔𝑎𝑡𝑒 𝑀𝑒𝑛’𝑠 𝑅𝑒𝑝𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑣𝑒 𝐷𝑒𝑝𝑒𝑛𝑑𝑒𝑛𝑐𝑦?” In the webinar, Prof Brownlee commented that people who cannot gestate face morally significant disadvantages due to radical differences in bodily ability. These people – including all male adults – are profoundly dependent on people who can gestate for reproduction and parenting opportunities. Gestational inability and gestational dependency give rise to claims to mitigation and accommodation. When we appreciate the normative significance of men’s gestational dependency, we might treat men more justly by seeking to mitigate their disadvantages. In doing so, we might better protect the rights of women and rights of girls whose experiences of oppression so often entwine with patriarchal societies’ unacknowledged efforts to counteract men’s dependency. This webinar not only offered valuable perspectives on rethinking reproductive justice and its broader implications, but also sparked interesting and engaging dialogue among participants. @hku_mehu @hkumed #ConversationsAndConnections #Webinar #HumanReproduction #Ethics #ReproductiveRights

⭐ Post (English Urdu Mix) Spermatogenesis – Development of Sperm Today’s post is about how sperm is formed in the male body. Spermatogenesis ایک ایسا نیچرل پروسیس ہے جس میں testis کے اندر sperm بنتے ہیں۔ It usually takes around 64 days, اور روزانہ millions of new sperm پیدا ہوتے ہیں! ✔ What is Spermatogenesis? Process by which sperm cells are produced inside seminiferous tubules. Takes about ~64 days in humans. Body روزانہ millions of sperm بناتی ہے۔ ✔ Functions of Mature Sperm Head: DNA enzymes for fertilization. Midpiece: Energy powerhouse (mitochondria). Tail: Helps sperm swim towards the egg. ✔ Stages of Development Spermatid → nucleus جڑتا ہے، shape بنتی ہے Flagellum develops → tail بنتی ہے Mitochondria midpiece میں arrange ہوتی ہیں → energy Acrosome forms at the head → egg کو penetrate کرنے میں help Final mature sperm → Head, Midpiece, Tail ✔ Real-Life Connection Low sperm count, poor motility, abnormal shape → infertility risks Heat, smoking, stress, alcohol → sperm quality کم کر دیتے ہیں IVF/ICSI میں even one healthy sperm کافی ہوتا ہے fertilization کے لیے ⭐ Fun Fact A healthy male produces 200–300 million sperm daily, مگر fertilization کے لیے صرف 1 sperm کی ضرورت ہوتی ہے! --- 📌 Thumbnail Text (Thumail Idea) "Spermatogenesis Explained – How Sperm Are Made?"

Thank you @UZH_H2R specially @CavazzaLab for two days discussing the science, ethics and history of #HumanReproduction. An impressive and much needed multidisciplinary intiative.

இது ஒரே மாதவிடாய் சுற்றத்தில், 2 முட்டைகள் இரு வேறு ஆண்களின் விந்த**களால் fertilize ஆகும் போது ஏற்படுகிறது எனவும் மனித இனப் பெருக்கத்தின் சிக்கலான தன்மையையும், இயற்கையின் அதிசயங்களையும் இந்நிகழ்வு மீண்டும் வெளிப்படுத்துகிறது என்று நிபுணர்கள் கூறுகின்றனர். #Brazil #HeteropaternalSuperfecundation #TwinBabies #HumanReproduction #Offbeat #Oneindia #OneindiaTamil | Image: AI Generated

👨‍⚕️ Enrico Sertoli (1842–1910): When Morphology Means Function Long before routine stains, immunohistochemistry, or electron microscopy, a young Italian physician named Enrico Sertoli made a discovery that would only be fully recognized nearly a century later. 🧠 Who Was He? Born in Sondrio, Italy, he graduated in Medicine from the University of Pavia. In 1865, at just 23 years old, he published in Il Morgagni journal his landmark paper: “Dell’esistenza di particolari cellule ramificate nei canalicoli seminiferi del testicolo umano” (On the existence of branched cells in the seminiferous tubules of the human testis). In this pioneering study, he first described the sustentacular cells of the testis, later named Sertoli cells in his honor. 🔬 Microscopy in the 19th Century Using a Belthle microscope with achromatic lenses and corrosive sublimate fixation (no microtome or modern staining), Sertoli identified cellular niches, the organization of the seminiferous epithelium, and proposed a structural and nutritive function for these cells. 🗣️ Famous quote: “Form acquires its real importance when it is acknowledged as a function.” — Enrico Sertoli 🧬 Lasting Scientific Contributions Today, we know that Sertoli cells: 🔸 Nourish and support germ cells. 🔸 Form the blood–testis barrier. 🔸 Regulate the hormonal microenvironment required for spermatogenesis. 🔸 Are involved in phagocytosis of residual bodies. 🔸 Play key roles in immune privilege and male fertility. 📚 Legacy Despite its importance, Sertoli’s discovery was largely ignored during his lifetime. Only in the 1950s–1970s was his work rediscovered and appreciated through the studies of Teilum, Clermont, and Hess. His name is now immortalized in multiple medical entities: 🧪 Examples: • Sertoli cells • Sertoli cell tumor • Sertoli-only cell syndrome • Undifferentiated Sertoli cells in gonadal dysgenesis 📖 Reference: Patriarca C, Colecchia M, Clerici CA.

🚨 Attention: Key updates on ESHRE guidelines! 🚨 One of the most important talks I attended was by Prof Rod Mitchell @RodTMitchell : “ESHRE good practice recommendations on fertility preservation involving testicular tissue cryopreservation in children receiving gonadotoxic therapies.” 🧬 STUDY QUESTION: How should fertility preservation be managed in child and adolescent males undergoing gonadotoxic treatments? ✅ SUMMARY ANSWER: 42 recommendations were developed to guide every step of fertility preservation in boys where traditional methods (like semen cryo or surgical sperm extraction) aren’t possible — from identifying candidates and counselling, to tissue biopsy and cryopreservation logistics. This is a HUGE milestone for clinical practice and research. 📖 Read the official ESHRE good practice recommendations here: 👉 doi.org/10.1093/humrep/deaf1… 🌐 Learn more about fertility preservation in prepubertal and adolescent males: 👉 orchid-net.com/ #ESHRE2025 #FertilityPreservation #TesticularTissue #Cryopreservation #ReproHealth #PediatricOncofertility #Andrology #HumanReproduction @ESHRE @theESHRE5 @SIGFertPreser

"Human reproduction is commonly portrayed as a gigantic marathon swimming event in which the fastest, fittest sperm wins the race and prize of fertilizing the egg. Yet another male dominated fantasy about the creation of life. The notion that human sperm once ejaculated, begin a frantic race to reach the egg has completely overshadowed the real story of reproduction. A 2020 study revealed that in fact there is a communication system between the EGG and sperm. The egg has the ability to repel certain sperm with a molecular mechanism causing them to swim slower and also attract certain sperm by releasing a chemoattractant helping them move faster. Cervical mucus call L- Mucus helps filter out any low quality sperm, Bye Boy! In the study Fitzpatrick is quoted "Follicular fluid from one female was better at attracting sperm from one male, while follicular fluid from another female was better at attracting sperm from a different male…. This shows that interactions between human eggs and sperm depend on the specific identity of the women and men involved." Once SHE makes her choice and the sperm begins to penetrate the egg, the egg then releases a chemical response that causes all of the other sperm's heads to pop off. Yep, mass decapitation. ⠀ And to keep things in perspective, the male sperm is the smallest cell in the human body while the female egg is the largest, who run the world?" #girls *Due to multiple messages I’ve received I feel the need to share that this is a process of the egg discerning for genetic compatibility and NOT a conscious process! ~ via Wildmoon Doula Source: Fitzpatrick, J.

人間の生殖は一般的に、最も速くて適性のある精子がレースで勝ち、卵子と受精するという巨大なマラソン・スイミング・イベントのように描かれている。 生命の誕生に関する男性優位のファンタジーがまたひとつ生まれた。 人間の精子は射精されると、卵子に到達するために必死のレースを始めるという考え方は、生殖の本当の物語を完全に覆い隠してしまっている。 2020年の研究で、実は卵子と精子の間にはコミュニケーション・システムがあることが明らかになった。 卵子には、分子メカニズムによって特定の精子を反発させ、泳ぎを遅くさせる能力があり、また、化学誘引物質を放出して特定の精子を引き寄せ、その動きを速める能力もある。 L-粘液と呼ばれる子宮頸管粘液は、質の低い精子を濾過する働きがあります！ あるメスの卵胞液はあるオスの精子を引き寄せるのに優れていたが、別のメスの卵胞液は別のオスの精子を引き寄せるのに優れていた。 このことは、ヒトの卵子と精子の相互作用が、関与する女性と男性の特定のアイデンティティに依存することを示している。 女性が選択し、精子が卵子に侵入し始めると、卵子は化学反応を起こし、他の精子の頭をすべて弾き飛ばす。 そう、大量首切りだ。 ⠀ 男性の精子は人体で最も小さい細胞で、女性の卵子は最も大きい。 #girls Fitzpatrick, J.
