צעד גדול לשוורצנגר, צעד קטן למוסר

בשנת 1994 נודע כי לא רחוק היום בו המדע המודרני ימצא דרך להכניס גבר להיריון. הרחם, שהיה מאפיין נשי ייחודי לאורך כל ההיסטוריה, ישתנה ויערער את יסודות הבריאה. ומי יהיה הגבר שייבחר להיות הזכר ההרה הראשון? ארנולד שוורצנגר בכבודו ובעצמו, כך לפחות על פי סרטו של איוון רייטמן – "ג'וניור". שוורצנגר מגלם בסרט מדען המגיע להישג פורץ הדרך יחד עם הקולגה שלו דני דה-ויטו, שאיתו שיתף פעולה גם בסרטם "תאומים" (1988) בו מחקרם עוסק באופן מוזר בהפריית מבחנה מסוג חדש הלוקחת את הזרע ממספר גברים שונים.

בחודש שעבר נודע כי שני מדענים משנגחאי עשו צעד חשוב בדרך להגשמת חזונו של שוורצנגר, כשחצו גבול מוסרי שבעבר איש לא העז לחצות. המדענים השתילו בעכברים זכרים רחם, ואז הזרימו דם מעכברות נקבות אל הרחם שבגוף הזכרים. כך הצליחו הזכרים "להתעבר" וכמה מהם הפכו ל"אימהות". במאמר שפרסמו החוקרים במאגר המחקרים המדעיים BioRXiv הם התרברבו: "לראשונה, הצלחנו לייצר מודל של היריון זכרי ביונקים".

מדוע בכלל לייצר מודל כזה? ייתכן שהמדענים הסינים עושים זאת כדי להיות חלוצים בתחום חדש, או אולי מרצון לקדם אג'נדה טרנסג'נדרית שמטרתה לאפשר לגברים ביולוגיים המזדהים כנשים ללדת. קשה לדעת.
